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!!

Mary is teaching me a different style of running that has less impact on my back and knees that really helped me... She has a great positive attitude, always encouraging me. A great coach, I would highly recommend her to anyone who is serious about their training. Be prepared to work hard!

Mary is an excellent trainer and coach. She has a passion for fitness and sports and it shows in her work. Since working with her, my cardio has improved as well as my muscular strength and endurance. I am a cross fit athlete and my sessions with her have greatly benefitted my athletic performance.
