Katie BirchallWellness Membership Director

Katie’s passion for nutrition began early on in high school when she was ran track and learned how important it is to eat right to perform well. She has always been a big people person and knew that she wanted to one day take her passion for nutrition and use it to help others.

Katie enjoys riding horses, spending time friends and family, and travelling in her spare time.

William Gillespie
William GillespieWellness Director
William, a native North Carolinian, was raised about an hour north of Raleigh on Kerr Lake. He attended the University of North Carolina at Chapel Hill where he earned his degree in Exercise and Sport Science.

A passionate cyclist, William has experience working both with bicycles and people. He has worked as a bike mechanic in the past which took him to Southern Utah. He also has coached track and field athletes as well as cyclists and triathletes, working in the weight room and on the road.

Outside of work, William loves to ride bike, get outside for hiking, backpacking, and climbing, hang out with his friends, and explore the local craft beer and coffee scene. Bonus points if he gets to hit multiple in a trip – so if you ever want to take a ride to a local café (or brewery), William is your guy!
