Currently the TopMind Team is expanding and we are looking for enthusiastic, entrepreneurial team-players (psychologists and marketeers). Interested to join our virtual and buzzing team? Please send us an email: marcia@topmind.com.


The founder of TopMind is Anne-Johan Willemsen. He is a leadership fitness trainer for executives, professional athletes and entrepreneurs.

Having worked for 10 years as a manager at Procter & Gamble and Shell, he is well aware of the challenges entrepreneurs and managers have to face each day. Since 2006 he started as a meditation teacher and over time developed a training method which allows you to train and improve your mental fitness with practical do-it-yourself training.

The effectiveness of the TopMind method has recently been researched by the University of Amsterdam / Amsterdam Medical Centre (AMC 2015) and showed a significant improvement in stress reduction, work engagement and empathy after a 100 days TopMind program. The results were published in a renown academic international medical Journal (Int. Journal of Surgery Nov 15).

Anne-Johan is married and father of three boys and lives in Haarlem-The Netherlands.
