  • “Competitive cyclists spend considerable time on training programs and bike components, yet they fail to spend any time or effort in the most important thing – their internal motor.  Jeff has helped me tremendously in my everyday nutrition, race day prep and in-competition fueling. His expertise has led me to my best year on the bike to date!”

    “Jeff is an amazing dietitian. He gave me simple, easy-to-do suggestions that made a huge difference in my diet. When my season started Jeff prepared a detailed fueling and supplementation plan for my training and races which allowed me to train more effectively and race harder. I achieved a PR on the Olympic distance triathlon this year, cutting 25 minutes off my time from last year.”
