Coach Stef

Growing up, Stef was always active, participating in various team sports like basketball, soccer, and volleyball, just to name a few.

She has since ventured into competitions including Flex on the Mall, Battle of Baltimore and Charm City Throwdown, all in the name of fun and fitness! Stef has a soft spot especially for those new to CrossFit; she loves seeing their progress and their surprise as they discover the fun in working out.
