Coach David is husband of 8 years, a father for 1, a software architect for 15, an endurance athlete for 13, and a USAT Cetified Level I Coach for 4 years. He has coached athletes at all levels, including leading a Rookies program that guided multiple people to complete their very first triathlon. In the following years, he has built multi-year relationships with his athletes by helping them intelligently progress from Olympic to 70.3 to Ironman events. He has even inspired a couple of athletes to follow his progression into coaching.

By coaching many athletes of various backgrounds and time availability, David has gained valuable experience integrating training into their weekly schedule so as to minimize friction with family and work. His journey started with humble beginnings.

It’s difficult to believe that when he started, he could barely run 2 minutes without walking breaks when he worked to complete his first marathon. Despite this accomplishment, David let himself become a 250-lb coach potato before a high-blood pressure epiphany caused him to start devouring endurance literature instead of burgers. Two years later and 80 pounds lighter, Coach David embarked on a very successful progression, first completing sprint triathlons until he moved on to iron-distance triathlons. Throughout this adventure, David has thoroughly enjoyed educating himself on all aspects of triathlon training while developing particular strengths in periodization methodologies, heart-rate and paced-based training, and "dialing in" a nutrition/hydration plan.

David loves triathlon training because of how it changes you. Previously unthinkable workouts become routine, and this improvement redefines your perception of what you're capable of accomplishing. By going from an obese underachiever to a continuously improving Ironman, triathlon has transformed his life, giving him so much more confidence and energy than he ever had before. This transformation has proved that triathlon has the power to revolutionize your life if you let it.

His coaching goal is to guide you through that same wonderful journey. Despite all the external stimulus of fancy bikes and sleek spandex, David found this journey to be largely an internal one. He continues to do triathlon because he want to find and feel that inner spirit that is only exposed when many miles have stripped away all shields of adrenaline, caffeine, and glycogen. He coaches to help others discover that same passion.
