David Sammel is a world renowned tennis coach with two players competing in Tokyo. He wrote the best selling book Locker Room Power and founded the online mindset programme to help declutter the minds of competitors in sport and business. 

He specialises in leadership skills in competitive environments using surprisingly non-combatitive techniques, favouring the power of vulnerability, the strength of humbleness and the persuasiveness of soft skills. Enjoyment and environments enthused with the curiosity of possibilities are his answer to rules. “If there is a need to increase discipline and rules then the philosophy and culture are failing”.
