Claude Keller

'To inspire, to develop, and to unfold', all pertaining to human potential; these are the three key notions around which Claude Keller's successful coaching and  training practice has been revolving for more than ten years. With a degree in physics from ETH Zurich, Switzerland, and an MBA from Cornell University, Ithaca, USA, he beautifully connects intrinsic interest in people and the human mind with a personal, realistic approach, in support of  individuals, teams and corporations. 
Because of his degree in acting from the American Academy of Dramatic Arts, Los Angeles, USA, he feels very comfortable working in more cultural settings too. Due to all these different perspectives and international experiences he has developed a keen insight into people and characterizes them with astuteness.
Claude has expanded his knowledge with a lot of continuing education.  After having trained at the Solution Surfers school for brief coaching in Basel, Switzerland, he became a professional certified coach (PCC), acknowledged by the International Coach Federation (ICF).
