The Markee Story
From 250 lb and broken to 195 lb and a black belt.
Markee McCrimmon walked into Logic with no athletic background. Today he's one of Philadelphia's most respected coaches and the living proof that the system works. A magazine-ready, 600-word narrative is available on request, plus before/after photography.

Head Coach & Owner
Dennis A. Pressey Jr.
The man who runs the gym.
Dennis Pressey Jr. has spent 18 years training and competing in Brazilian Jiu Jitsu, and 12 years teaching it. He is the Head Instructor and Owner of Logic Jiu Jitsu in Philadelphia. His Black Belt was co-awarded at JT Torres's academy by his professor Kristian Woodmansee and JT Torres together — a recognition of the standard he met as a competitor, coach, and longtime teammate inside the lineage.
He competed at the highest levels — IBJJF Pan American Championships, Fight 2 Win, UFC Fight Pass — before taking over Logic to fix the two things he saw broken at most academies: beginners getting ignored, and kids treated as an afterthought.
