Essentials That Touch the Heart

Attune was founded in 2004 by Sonja Vlaar. Attune is English for "tuning in". We tune in to resilience, brainpower and essentials that touch the heart. 

Attune's goal is to contribute to change and transformation: of the individual, of the team and of the organisation/company. We do that with coaching. We embrace open dialogue from a systemic approach. We are constantly working on our own programs and Conversations with Impact®.

We integrate best practices and tools from professional coaching with insights from positive psychology, the neuroscience and systems approaches. We are experienced and certified in these domains. We use online assessments to measure the initial situation and progress in building resilience and capacity for high performance.

Conversations with Impact

When was the last time you had a really good conversation? A conversation that does not just consist of two serial monologues, as it often happens. In that really good conversation you hear yourself saying things that you did not know about yourself before, you hear how the words that the other says resonate within you. Words you thought you had lost and words that make the conversation so lively that the two of you reach a different wavelength together. To your experience, that good conversation still has an impact on you today.

"The coaching sessions with Sonja are action-oriented. I developed new habits to better understand myself. I left every session having learned something new, whether it was about myself or a new technique to reflect or to use in reflection. I would recommend Sonja as a coach to anyone who is interested in growing as a leader. Her coaching allowed me to improve my way of showing up every day and in crucial situations, so I could make better choices. I cannot thank her enough for her coaching over the past 6 months - it was always the highlight of my week ”  -  Signed: Maria Selde, M&E Consultant. guide house (from December 2020) and M&E Officer @Search for Common Ground (May-Nov 2020) -

February 2021: Sonja's age is a plus because she understands what is going on with senior managers with personal questions in their work. I gained insight into how an important core value has a positive but also negative effect. Sonja acts on what is happening in the moment. Ze substantiates this with reference to theory, her experience and practical exercises. It was an eye opener that I can influence my brain in simple ways and that it also makes me feel different. I can still go back to the Neurozone report that gave me new insights and has brought useful tips. - Mabel Bross, Manager Youth Protection Brabant -

“The coaching solidified me as a leader to deal with managerial issues, coping with difficult circumstances and getting the best from my team. My ability to confidently lead the conversations with my superiors and colleagues increased significantly. I learned to review issues form various angles. I transformed to be calmer in resolving problems and looking for alternative approaches. There has been no session which I left without learning and with fun! Not tiring at all. ” - Prudence Masako, EngenderHealth Tanzania
