Coach Mary gave me the confidence to train for and complete my first 3 Ironman 70.3 races! I live in California and was able to submit videos of my run gait and swim gait as well as consult her regularly on the phone. Coach Mary will get you to the finish line!!

I worked with Mary for six months as I trained for my first 70.3. She was exactly what I needed in a coach: someone to balance consistent training against the craziness of everyday life. Injuries, work commitments, vacations, and beyond. Mary made sure my training was on track, adjusting to all of life's interruptions. I arrived at the start of Ironman 70.3 Texas prepared and confident thanks to Mary and had a wonderful day. I look forward to working with Mary for Ironman Texas..."

I have been working with Mary for over half a year now, and she is amazing. She took the time to really get to know me, my goals, my strengths, and my weaknesses and created an individualized plan for me. With her coaching and motivation, I was able to shave off half an hour on my latest 70.3. I am grateful to be able to work with Mary and consider her not only my coach, but a friend.
