USA Triathlon Certified Coach
USA Cycling Level 2 Certified Coach


I have been racing triathlons, bike races and running races since 1998. I had a very grateful opportunity to begin coaching with Mike Ricci and D3 Multisport in 2012. With this triathlon tenure, I have learned so much as an athlete, as a triathlon coach, about myself and about what makes my athletes tick! I am personally racing competitively, but my goals are to see my athletes succeed.

Seeing their happiness and satisfaction of overcoming a hurdle, working through a challenge, or having an ah-ha moment in racing and training is genuinely a pride point.

I've been fortunate to race the Ironman World Championships (2008), 70.3 Worlds (2017), and earn a few Age Group National titles in three different distances. Helping you achieve your triathlon goals is what I aim to do as a coach.

I look forward to meeting you at a Team race or in the Team's FB group!
