I’ve been playing basketball for over 30 years. And have been coaching and training for more than 18 years. Basketball, in my opinion, is the greatest sport on the planet. Not only are you challenged to perform as an individual player, but also challenged to perform as a team player. The lessons I’ve learned on the basketball court have often times effectively guided me in my off-the-court challenges. It is for those reasons that I have come to truly appreciate what the game has afforded me. Through training, I hope to help others not only become great players, but also experience the same benefits and opportunities I have come to enjoy.
