  • 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.

  • 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.

  • 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.

    VP, HR Europe and Central Asia, Metso

  • 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.

  • 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.

Leadership team development

  • 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.

  • 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

  • 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

  • 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.

    Henrietta Moon

    CEO & Co-founder, Carbo Culture

  • 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.

    Miimu Airaksinen

    Suomen Unicef ry., hallituksen puheenjohtaja

  • 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.

Executive Coaching

  • 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

    CEO, Finnish Forest Industries Federation (Metsäteollisuus ry)

  • 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

  • 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

  • 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

    Company

  • 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.

    Executive

    International company

  • 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

    International company

  • 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.

    Elli Mäkilä

    CEO, Storybound Oy; Chair of the Board, Tanssin Talo (Dance House Helsinki)

  • 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.

    Senior Executive

    International company

  • 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.

    Merja Kannisto

    Senior Vice President, Nordea.

  • 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

  • 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 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

    Chief Information Officer, Ministry of the Interior

  • 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.

    Satu Mäkelä

    Director-General, Centre for Economic Development, Transport and the Environment for Southeast Finland (ELY Centre)

  • 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

  • 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.

    Senior Executive

    Public sector

  • 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.

    Senior Executive

    Public Sector

  • 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.

Coach Development

  • 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

  • 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.
