Your Coach Matters More
Than Your Gym
Most people quit martial arts because they feel lost — thrown into a class with no structure, no feedback, and no plan. Every coach on this page has a single job: make sure that doesn't happen to you.
Dennis A. Pressey Jr.
Black Belt, 2019 — awarded by Kristian Woodmansee & JT Torres
18 years training and competing. 12 years teaching. Dennis runs Logic because he saw too many beginners get ignored at big gyms — and too many kids get treated like an afterthought. Every program here exists because he designed it to actually work.

Markee McCrimmon
Black Belt
Kids & White Belt Instructor
Promoted 2024 by Kristian Woodmansee & Dennis Pressey Jr.
8 years training · 4 years teaching kids and white belts
Teaches Kids · White Belt (Mon/Wed/Sat)
Markee's path through Logic is the academy's gold standard transformation — he started at 250lbs, severely depressed, and earned his black belt while losing nearly 60lbs and rebuilding his life. Today he runs Kids classes and the white belt beginner classes. New students consistently say Markee is the reason they came back for class two. He coaches with patience, clarity, and lived experience.

Matt is also a parent — he coaches other people's kids the way he'd want his own coached.
