Background:  I grew up as a competitive swimmer and swam through my years at University.  I had a successful career as a swimmer, and wanted to continue competing in sport. I turned to triathlon after graduating from Emory University in 2009, and casually began participating in local races.  While working as a swim coach for a youth swim team, I got certified in personal training, and then transitioned to working as a personal trainer full-time.  After 2 years of working in a gym, I decided to go back to school for Nutrition and moved to Colorado to complete a 2-year Holistic Nutrition program. While living in Colorado, I began coaching for the Colorado State Triathlon team, and my focus shifted to triathlon.
