My name is Bill Foran and I am the Strength and Conditioning Coach for the Miami Heat of the NBA. I have known Doug for over 15 years. He has served as a nutritional consultant to me for all of these years.

   I am also friends with other strength coaches around the NBA that use Doug for his formulations and nutritional/training expertise. He was the Phoenix Suns Nutritionist for 10 years alongside my friend and fellow strength coach Robin Pound.

   I have heard Doug speak and have read his books along with other great research papers. I highly recommend him and his training staff for anyone wanting to improve their health or the health of their clients/patients.
