About

I’ve owned gyms for 15 years. I know the chaos—spreadsheets everywhere, decisions made on gut feel, and progress that’s hard to measure. I built Gym Engine OS so owners can see every key number in one place: members, attendance, retention risk, leads, conversion, and revenue. The result: clarity → better decisions → growth. What I’m known for: • Scaling to 300+ members with 139% growth in 2 years • Turning messy ops into simple systems (pricing ladders, retention triggers, dashboards) • Coaching owners to run profitable, low-stress gyms
