My approach to supporting gymnasts, parents, and coaches comes from my own experience as a high-level gymnast that struggled with food and her body. Like many of you, my career was plagued with injuries that were largely related to underfueling, though I was clueless as to the effects my nutrition had on my body and performance. 
 
I didn’t learn to fuel and nourish my body until college, which was after my gymnastics career had ended. So much of what I write and speak about is what I wish I could have told my 16-year-old gymnast self. 
 
As I became more involved in nutrition, I realized very quickly that a “one-size-fits-all” approach and “just do it” don’t work. Not only does this not work, but this approach often makes the food + body situation worse.  

I’m a pediatric and adolescent sports dietitian nutritionist that specializes in nutrition for the gymnast.
