In our global business unit, we’ve been working with Sari Vuohtoniemi of True Potential on leadership development since 2019 – more than six years now.
During that time, Sari has played a central role in shaping our leadership culture and supporting the growth of 120+ leaders across Europe, Asia, and the Americas.
Stephanie Reithofer
Global Business HR Partner, ANDRITZ Pulp & Power
Her work has been instrumental in helping our leaders navigate a complex, fast-changing environment. The programs Sari has designed and delivered, four rounds in total, for all of our global leaders, have consistently addressed timely, meaningful themes, with a strong focus on coaching-based leadership, emotional intelligence, self-awareness, resilience, psychological safety, building high-performing teams, and purpose-driven leadership.
One of the most impactful aspects of our partnership has been Sari’s ability to strengthen our leaders’ sense of empowerment and ownership. Her programs aren’t just well-received, they drive genuine, lasting change. She has also coached numerous leadership teams, including our senior executive team, with excellent results.
Sari’s professionalism, deep experience, and ability to connect with diverse audiences make her an exceptional partner in leadership development. She’s inspiring and creates an atmosphere of open dialogue with ease. She’s genuinely willing to understand business needs beyond the surface. We look forward to continuing our collaboration and expanding these initiatives further, as we consider them vital to our business success.Stephanie Reithofer

Sari Vuohtoniemi of True Potential brought her professional expertise to help us support our managers – both through organizational change and in building a stronger coaching-based leadership approach at VTT.
We ran eight groups in total, with around 100 leaders and managers completing a fully virtual training program.
Sari Ek-Petroff
HR Business Partner, Learning & Development, Talent and Culture, VTT
The program gave us an excellent foundation for building a coaching-based leadership culture and a stronger feedback culture at VTT. Feedback from the managers who took part in the Coaching & Feedback program was highly positive; the training was seen as offering genuinely useful tools and approaches for everyday leadership and for developing staff capabilities. We’ve found our collaboration with True Potential rewarding and productive, and our work with Sari continues.

In 2021, I took part in Sari Vuohtoniemi’s Coaching & Feedback program, delivered virtually for VTT, in which Sari challenged conventional, one-dimensional management practices in a way that was at once simple, inventive, and deeply thoughtful.
Genuinely refreshing, interactive coaching, paired with a real depth of understanding in building coaching skills. Inspiring, useful, shared learning.
Sonja Martikainen
Head of Business Intelligence, Strategy and Business Intelligence, VTT
Coaching as part of leadership is, above all, a mindset. You don’t know what you’re capable of until you try it. For me, coaching is a way of thinking – one where I guide the person I’m coaching to clarify the milestones and goals that actually matter for success at work. We also prepare for setbacks and think through who can help and support us along the way. At the same time, it guides me toward achieving team-level goals and toward finding solutions rather than dwelling on problems. It’s also, in its own way, a path toward a better life.
Coaching has been a rewarding journey for me in developing my own thinking, particularly in learning to shift perspective. I think about myself in new ways now, having stepped away from the rigid, externally imposed identity of traditional management. In its place has come real skill in emotional awareness, patience, compassion, and empathy, and, through that, better, more lasting results.Sonja Martikainen

Sari of True Potential got the employees taking part in the training talking, questioning their own ways of working and actively putting new approaches into practice.
She facilitated the sessions skillfully, made sure everyone had a chance to participate, answered even the difficult questions with real expertise, and created space for both discussion and live practice.

As a coach, Sari is engaging and inspiring. She built an atmosphere of trust in the training, and it was easy for people to fully commit to the exercises.
Our goal was to develop our IT employees’ coaching skills and give them concrete tools for the coaching situations they encounter in consulting work. We felt Sari succeeded at this extremely well.
Our Talent Project model, which relies heavily on coaching skills, is unique in the IT industry. It requires our software developers not only to have strong interpersonal skills, but also the ability to work through varied challenges using a coaching-based approach, so that the person being coached learns to solve the situation themselves going forward. This model works especially well alongside onboarding for junior talent.
We believe the learning from this training will show up concretely in the productivity and engagement of our client companies’ employees.Matti Lehtinen

The Self-Awareness and Growth as a Leader retreat was a powerful experience, both for personal growth and leadership development.
It helped me deepen my self-awareness and find new perspectives on leading people – insights that have been a real support in everyday work.
Susanna Mäkelä
VP, HR Europe and Central Asia, Metso
Sari brought strong expertise and experience to the process. Her way of combining theory, practical exercises, and personal guidance created a safe, inspiring atmosphere where it was easy to pause, reflect, and grow. The retreat strengthened my belief that leadership isn’t just a set of skills – above all, it’s the ability to understand yourself and others.

Taking part in the Self-Awareness and Growth as a Leader program was a truly valuable experience – it deepened both my self-awareness and my understanding of the different ways people operate.
Building the Enneagram profile, and working through it together, made visible my own natural patterns and the very different logic other people work from.
Leader
It built understanding and compassion, both for myself and for others, and brought concrete insights into how I lead and interact with people. It was valuable to reflect on my own behavior against others’ profiles and to see where different behavioral patterns actually come from. Altogether, the program was both inspiring and deeply meaningful. The reflection, discussions, and practical exercises created space to pause and gain insights that continue to support my work.
Sari is an outstanding coach. Her expertise in the Enneagram runs exceptionally deep, and her way of guiding the process is at once clear, gentle, and powerful. She created a space where it was easy to explore yourself and learn from others. I left the program with a lighter mind and a much more concrete understanding of my own leadership.Leader

Sari Vuohtoniemi of True Potential Oy trained our managers on using coaching as a tool in day-to-day management conversations.
This hands-on program deepened our managers’ ability to bring coaching into their own work. As a trainer, Sari is attentive and conversational, and her insight-driving questions drew participants naturally into dialogue, prompting real reflection on their own approach to managing people.

It’s always a genuine pleasure working with Sari. Her positive energy and her ability to focus on what matters most are what drive real change. She’s also masterful at helping people discover their potential, drawing on tools like coaching and the Enneagram. I can warmly recommend Sari as a professional coach and leadership consultant.

I have had the opportunity to collaborate closely with Sari Vuohtoniemi both at the leadership team level and through individual coaching, and I can strongly recommend her as a leadership and leadership team coach.
At the team level, Sari played a key role in strengthening how we work together in our global leadership team.
Simone Tiberti
Vice President, Global Delivery Operations, KONE
She helped us build trust, increase openness, and create more direct and constructive interactions. The impact was tangible: dialogue improved, barriers came down, and the team operates today with greater effectiveness. What differentiates Sari is her ability to combine insight with pragmatism; she does not stop at awareness but ensures real behavioral change and measurable impact. Our collaboration continues, and I see her as a trusted partner in strengthening leadership performance.

Sari has successfully coached several global leadership teams at Kone.
I am also a member of a global leadership team, that was just appointed and met for the first time as a whole team when Sari coached us.
Minna Rouru
Vice President, People & Communications for Global Functions, KONE
The open and safe environment during Sari’s coaching, as well as the transparent feeling during the team session, allowed for genuine sharing of enneagram profiles and insights, fostering a culture of trust and collaboration within the team.
This helped to get a view of the collective strengths and development areas of the group, facilitating better alignment and utilization of resources and skills.Minna Rouru

Thanks to the development process, we’ve stepped up as a management team.
Nowadays our purpose and role as a management team is clear, we talk less about our functions and departments, and people are more aligned and committed to working as a team.
Henrik Albrektson
General Manager, ParkerHannifin Sales Company Nordic
We have open discussions about sensitive topics. We got to know ourselves and team mates better and have strengthened our working relationships and team dynamics. Our trust, spirit and commitment in the team have developed a lot by going through the process.
Sari Vuohtoniemi and Elina Ämmälä were very professional and knowledgeable of coaching our team to grow. The journey never stops and new team members who are joining along the way are adding new perspectives and energy. We will continue to work on our development and follow through on the ideas developed together with Sari and Elina!Henrik Albrektson

It was incredibly valuable for our global extended leadership team to spend a day with Sari and the Enneagram.
Getting to know each other’s personality strengths, and blind spots, has enabled much clearer, stronger communication, and ultimately a better way of doing business together.

The composition of UNICEF Finland’s board was new, and we wanted to build a strong foundation for the new board to work from.
Sari Vuohtoniemi of True Potential brought her professional expertise and coached us specifically on clarifying our goals and how we wanted to work together as a board.

The benefits of working with Sari have been clear for us.
Our leadership team’s way of working has developed enormously, and the Enneagram model has become an internal ‘language’ for us.
Tuomas Salusjärvi
Senior Vice President, Valio
We’ve used the Enneagram model to build our emotional intelligence and self-awareness, and our ability to lead both ourselves and different kinds of people. We use it to strengthen collaboration, work through internal issues, and keep improving in our roles, especially in how we lead across multiple levels of the organization, both as individuals and as a leadership team.

I’ve worked with Sari across three different leadership roles since 2018, more than seven years now.
What matters most to me is her ability to challenge my thinking through difficult questions, pulling it out of its familiar grooves in a way that often leads to something simple yet essential, the kind of insight that actually stays with you in everyday work. Our conversations carry a spirit of openness and respect, and Sari’s warm presence makes even the toughest topics feel approachable. I’ve found our collaboration both valuable and genuinely enjoyable.
Paula Lehtomäki

We started working together at a point when my role was going through some really significant changes, and I needed deeper reflection and sparring on which direction to take.
Over the course of the process, we didn’t just talk through my thinking, in many cases we also identified what things physically felt like, and experimented with looking at situations from different perspectives, using space and different roles.
HR Director
International publicly listed company
I learned, in a completely new way, to recognize my own reactions to things and situations, and to anticipate and manage them. Sari is an incredibly calm and safe coach, and her range of methods always offered new ways to work through difficult, even thorny issues. I’d recommend Sari to anyone with the willingness, readiness, and courage to discover genuinely new sides of themselves, and find surprising resources for their own leadership in the process.

Sari has an incredible ability to create an atmosphere of trust. What’s more, her knack for asking exactly the right question at exactly the right moment helps your self-awareness genuinely develop.
I’ve learned to become more aware of my own limiting thought patterns and to understand what’s behind them. That’s helped me grow into a more present, calmer leader, even in challenging situations.
Henna Rundgren
Director of Digital Marketing, Benemen
For me, Sari has been a truly valuable guide toward connecting with my authentic self and inner wisdom. I recommend Sari as a coach to anyone who wants to grow as a leader, a person, a friend, or a parent, and to learn to recognize their own limiting beliefs.
Henna Rundgren
Director of Digital Marketing, Benemen

Sari is a fantastic coach, even remotely, we built a trusting, immediate rapport within moments.
She guided me beautifully on a journey of discovery into myself, and I came away with some genuinely surprising insights. Understanding your own strengths and challenges supports personal development and builds confidence. Warmly recommended!
Sirpa Soini
Director, THL (Finnish Institute for Health and Welfare)

I needed support and guidance to work through a complex situation at work and to lead myself forward in a constructive, dynamic way through a challenging period.
The most valuable thing about Sari’s coaching was that it let me arrive at real insight – into situations, events, and emotions – and see them as they actually were, becoming aware of my own thoughts, observations, and attitudes.
Senior Executive

As long as you’re not aware of them, it’s impossible to act, solve problems, or create change. In the safe, understanding environment Sari created, and the connection that formed between us, it became easy to take new, dynamic approaches to things I’d been “stuck” on for a long time. Thank you, Sari! I recommend this to everyone.

Going into the coaching process, my goal was to clarify my own direction for development and build a clearer understanding of the skills and ways of working I need to move toward both my own goals and my organization’s.
Starting the process gave me the chance to frame my goals in a new way and identify tools that support leadership development and remove obstacles from its path.

Sari Vuohtoniemi created an atmosphere of trust that made open, constructive dialogue possible. I valued her ability to listen and to help me structure my goals at the start of every session. Reviewing my goals helped clarify my own aims while also giving me the chance to reassess them. The sessions combined theory and practice, offering concrete models that supported my growth as a leader. I recommend Sari’s coaching to anyone in a leadership role.

When we started the program, I reacted to things emotionally, too quickly, and got “blinded” by things that ultimately weren’t as significant as I thought.
Working with Sari, I’ve come to understand my personality and my reactions much more clearly.
Leader

I feel I’m now able to direct my energy in a more productive way. Sari and I built a clear picture of what I do effectively today and what I do less effectively, and what I should keep doing – or change – to achieve the reason I came in the first place: reaching my goals going forward. I also got well-grounded, fact-based feedback and suggestions, instead of the vague statements that can be typical in this kind of work.
I recommend Sari’s coaching to anyone ready to look deeply at themselves and challenge how they work. Sari has a gift for asking questions that get you thinking – really examining your own behavior and asking yourself “why.” Why do I behave the way I do? Why do I care as much as I do?”Leader

True Potential and coach Sari Vuohtoniemi offered a rare combination of business acumen and human understanding, paired with dynamic ways of working.
I particularly recommend Sari’s coaching for senior executive and board-level needs, where the questions go beyond the operational and the routine. Working with Sari is a journey into your own deepest resources – exactly as the name True Potential suggests.

As a leader, I found the personal coaching process with Sari Vuohtoniemi genuinely helpful – in clarifying my own role, developing my self-reflection, and sharpening how I present myself.
The work has been enjoyable and focused precisely on the right things, agreed in advance. It also helped that we tracked agreed metrics from the start of the process and could follow the results achieved in concrete, numerical terms. I believe the benefits of this coaching will show up in business results going forward.

The personal coaching process with Sari was, without question, the best leadership development program I’ve taken part in across my twenty-year international leadership career.
Sari helped me discover entirely new sides of myself and develop my patterns of thinking and behavior. The finishing touch was the Enneagram training Sari ran for my international leadership team.

Sari Vuohtoniemi served as coach for the “Reforming the Public Sector – Enabling Leadership” training program from 2018 to 2021, personally coaching more than fifty leaders from ministries, government agencies, municipalities, and cities.
With her outstanding, strong professional expertise, Sari has moved the public sector’s cultural shift forward – toward coaching-based, enabling leadership – by strengthening leaders’ own capacity for reflection, making an important contribution to the program’s goals.
Tero Vuorinen
Program Director, HAUS Finnish Institute of Public Management
Her solution-focused approach in particular has drawn a great deal of praise. Sample feedback: “She was an excellent coach – every session got us into a solution-seeking mindset, and I got real, practical help with my leadership from her,” and “Sari was simply an outstanding coach, and I had a few significant ‘aha’ moments through the coaching.” Thank you, Sari, for your fantastic contribution to this program!

Sari Vuohtoniemi was my coach as part of the Finnish central government’s senior executive “Uudistuja” (Renewer) program. From our very first session, I was struck by Sari’s ability to build a springboard straight into the deep end of the pool.
I realized this was a chance to explore how my own rules and boundaries shape my thinking and my actions.
Minna Karvonen
Director, Ministry of Education and Culture
I decided to open myself up to coaching and dive into the dimensions of thought and experience that shape my work as a manager. It was worth it. Sari’s approach – empathetic, gently persistent, trusting, and trust-building. is genuinely unique. Her deep grounding in coaching methodology combines with a quick read of what the person she’s coaching actually needs.
That combination of situational awareness and skill guides you to discover new resources within yourself, let go of unnecessary weight, and clarify what really matters. I was struck by how Sari’s coaching opened up perspectives that support my everyday growth as a director, while also reminding me what a meaningful life is actually aimed at.Minna Karvonen

I took part in a leadership program for senior central government executives, and one of its best elements was the coaching with Sari!
Sari’s skill at drawing the answers to my own nagging questions out of me was impressively effective and professional. Highly recommended!
Tapio Aaltonen

I was in a situation involving a lot of change, along with a range of people-management challenges and development needs.
The most valuable part was the forward-moving reflection, which gave me a number of real insights, both personally and professionally. I also picked up new tips and theoretical frameworks for moving things forward. I’d particularly recommend this to leaders going through a change process or working through difficult management situations.

I was in a situation where my area of leadership responsibility had grown, and I felt I was leading it in a fairly fragmented way. On top of that, a lot of the strain came from my own ideas about what a “perfect leader” should be.
I got to genuinely focus on myself and my own work, and to reflect on my own attitude. The coaching was true individual coaching – not training, and not general discussion. This kind of coaching should be available to every leader, regularly. Right now, I feel more confident, calmer, and better able to direct my energy toward the things that actually matter.
Johanna Nevala
Director, City of Kerava
-
Sari is an inspiring, positive coach with a genuinely broad range of skills!
The coaching began as part of Sitra’s program for senior government leaders, at a time when I was also going through major change in my own work. With Sari, I can always trust that the process works and that results follow.
Mia Nykopp
Development Director, Traficom
As a coach, Sari knows how to guide and encourage you toward finding what truly matters. Working with Sari, I gained important insights about myself and got the support I needed in the middle of a turbulent period.
The coaching always led to concrete action, ideas never stayed just ideas. Coaching is absolutely essential for every leader and manager, but also for experts and specialists. I recommend it to anyone who wants to grow and develop, both in their career and as a person. It’s worth challenging yourself, no matter how long you’ve been in working life.Mia Nykopp
Development Director, Traficom

The coaching process was genuinely valuable for my professional development. It was constructive, enjoyable, eye-opening, and at times even a bit unsettling.
Just three sessions were enough to set a conscious process of change in motion in me, grounded in improved self-awareness. As a coach, Sari is reliable, knowledgeable, and genuine. She managed to get me thinking through difficult things about myself in a solution-focused way.

It was easy to talk with Sari, and she helped me see things from a new angle. Among other things, we worked through self-awareness using the mind-body bridging technique.
I also did exercises between sessions. I noticed that things aren’t necessarily as big a problem as you imagine them to be. I got a lot out of the sessions and realized that, in some areas, I was a prisoner of my own thinking.

Working with Sari has given me valuable insights into my own patterns of thinking and behavior, and helped me recognize my strengths and areas for growth as a leader.
The coaching has provided genuinely useful, practical tools for managing energy and for facing and handling a range of leadership situations. The insights and tools that came out of the coaching are easy to keep using independently, even after the coaching process itself has ended.

I work as an executive coach and leadership developer. Growth and continuous development as a coaching professional matter deeply to me.
I wanted to strengthen the impact of my own coaching work. I chose Sari as my coaching supervisor because I already knew her as a colleague and valued her broad expertise, experience, and compelling presence.
Riitta Salminen
ICF PCC
Coaching supervision turned out to be a remarkable journey into myself, into my own mental models and beliefs. We built a trusting, open working relationship that made real insight and learning possible. Working through my own coaching cases anonymously gave me fresh perspectives on my work as a coach.
I learned a great deal about the interaction between coach and client. I became aware of my own patterns and reached deep into my own core. In coaching work, it’s essential to pause and give yourself time to reflect. It was powerful to experience firsthand what it actually feels like to unlock hidden potential. I’m grateful, and I warmly recommend Sari as a coaching supervisor.Riitta Salminen

In her development work, Sari brings three gifts to the table: her tremendous experience, a rich and deeply developed portfolio of transformational tools for drawing out human potential, and a big heart.
She genuinely makes sure her clients feel safe, seen, and supported throughout the work together.
Cristina Muntean
Founder, Coach, Consultant, Media Education CEE, Prague
I had the privilege of being coached and mentored by Sari. When I began the process, I was looking for help seeing the hidden layers of my own personality – ones you can only really face with the support of someone more mature. Sari earned my trust, helped me relax, and was my partner in reaching my goals. She drew on a wide range of methods and approaches, and was fully present throughout.
She never pushed anything on me – instead, she held space carefully, reflected back with genuine appreciation, and, at the same time, knew how to help me find the essential keys to my own transformation. Every session helped me reach a deeper, more multidimensional view of myself. Of course, everyone is ultimately responsible for their own growth – but having a coach like Sari alongside you on that journey makes it far more powerful.
I don’t hesitate for a moment to recommend Sari to any organization or individual for a potential development initiative. You’re in good hands – by the time your process is over, real growth will have happened.Cristina Muntean
