♥️ 10 YEARS. ONE OF THE ORIGINALS. ONE OF OUR FOUNDING MEMBERS. 🥊

Cory Zanganeh has been a Grinder for 10 YEARS. She was here when Grinders was just getting started, and she’s been throwing punches, putting in the work, and being part of this crazy Grinders Fam ever since.

Ten years is a LONG time. She’s seen the gym change, watched people come and go, celebrated wins, pushed through hard days, and somehow kept showing up through it all. 💪

Cory, thank you for believing in Grinders from the beginning and for being such an important part of our story. We wouldn’t be celebrating 10 years without people like you who helped build this place from the ground up.

10 years down. Still grinding. Still family. 🖤♥️
