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.

Group Exercise Director

Marian Lally, the Group Exercise Director at Rock Creek Sports Club since 2010, has more than 20 years of experience in the fitness industry. She is one of the “inaugural” group exercise instructors at Rock Creek Sports Club, teaching since it opened in 2000. Under her direction, the Group Exercise program has grown to include more than 65 classes a week taught by a team of over 45 instructors. Her management style is that of a “straight shooter” who remains diplomatic and open to new ideas. Marian loves RCSC and her awesome team of instructors! A former dancer, Marian’s love for Group Exercise led to her to achieve certification from the American Council of Exercise (ACE) in 1992. She served as the Aerobics Coordinator at the Silver Spring YMCA for seven years, and later became group Exercise Director at Gold’s Gym in downtown Silver Spring, MD. Marian is also a personal trainer and Pilates Mat and Reformer instructor at RCSC. She graduated from the University of Maryland with a B.S. in Journalism.
