Sharon Sellers

Personal Training and Operations Manager

Sharon writes: Born in Baltimore, I grew up as a quintessential army brat, moving annually and then settling in Florida after high school. I graduated from Florida State University with a Computer Science degree and spent 10 years as a software engineer, but embraced bodybuilding for my alter-ego. I took a few years off from work to be home with kids, and when it was time to get back into the workforce I followed my passion and became certified as a personal trainer. I was fortunate to be hired by Rock Creek Sports Club during the construction phase and have enjoyed many years and many roles here. Currently the Fitness and Operations Manager, I have the privilege of working with an incredibly talented and professional staff of trainers as well as maintaining an exceptional fitness facility.
