In medical practice for 20 years I have been in private practice as a family physician, a hospitalist, a full time faculty member, and a Cystic Fibrosis (CF) specialist.
I am a physician in my day job, which I work around my priorities as a husband, father, and triathlete.
I began competing in triathlons in 2005 and as I worked up to the Ironman distance, discovered that had issues with fluid and sodium balance. This led to carrying out research projects involving endurance athletes and more specifically work in Cystic Fibrosis, which in turn led to a relationship with Andy Blow and Precision Hydration.
I now am the director of a CF clinic in Kansas, and I continue to compete in triathlon with 12 full distance Ironmans under my belt. As an Ironman Legacy Athlete, I will be competing in the Kona Ironman World Championships in 2025.
