My Sports Dietitian: Eat 2 Win

“I have a busy family! A female teenage Level 9 gymnast, a male teenage football player, wrestler and an adult male triathlete all under one roof. They each have unique needs and Cathy has helped us meet them all! In a simple and easy to understand way, Cathy taught each person the importance of fueling their body correctly while eating food they enjoy. She works great with our teenagers and has helped me as a mom meal plan for the whole family.

Cathy always responds quickly when we have questions and always has a big smile on her face! We can't say enough great things about her!

Thanks friend!”
