John Burke:
Owner of the Dungeon Mixed Martial Arts Academy Since 1997.
Has been training over 27 years in the martial arts including:
Kung Fu, Wrestling, Boxing, Judo & Brazilian Jiu-Jitsu.
Instruction in Grappling
Submission Fighting & Ground & Pound Techniques
Kettle Bell Training and general combat conditioning

Have taught self defense, weapon retention, officer survival techniques to Law Enforcement, Military and other organizations over the years, but my first love is the mixed martial arts. Since residing on Cape Cod in the mid 90’s, I’ve been training people for kickboxing, grappling, and Mixed Martial Arts competitions. I’ve had fighters compete all over the world. Whether you just want to loose weight and get into shape, or want to train to fight any type of competitions, I will get you into that shape.

I also manage fighters and know most of the local promoters and match makers. I get you fair fights.

Yours in Combat,
John Burke
