We're on Frankford Avenue in Fishtown — easy to find, easier to park than you'd expect.
The fastest answer to most questions comes from stopping by the gym during staffed hours — our coaches are at the front desk from 6 AM to 8 PM Monday through Friday, and from 8 AM on weekends. For class booking questions, membership changes, or trial sign-ups, the front desk staff can handle everything on the spot. If you prefer email, we respond within one business day, usually faster. For new membership inquiries specifically, a senior coach will follow up personally rather than routing you through a sales process — because we'd rather answer your actual questions than read you a script. Hartwell & Sons is located at 2418 Frankford Ave, one block north of the intersection with Girard Ave. Street parking is available on Frankford and the surrounding residential blocks. SEPTA's Market-Frankford Line stops at Girard station, a four-minute walk.
Open from 5:30 AM to 10 PM. Coaches and front desk staff are on-site from 6 AM to 8 PM. The final two hours are member keycard access only.

“I emailed on a Sunday evening asking about starting the Coached tier after years off from training. Coach Lena replied at 8 AM Monday with a detailed answer and offered a phone call if I had more questions. That response — specific, no-pressure, genuinely helpful — was the reason I walked in the next day. That was 14 months ago.”
