Kevin Sheridan (also kid instructor)

Kevin Sheridan studied under Master Alliance instructors including Fabio Clemente. Kevin placed 2nd at the World Championships in 2008 and received his black belt in 2010. Kevin opened Sheridan Brazilian Jiu Jitsu to have a competitive studio to train locally.

Kyvann Gonzalez


Wow. Just look at Kyvann. This dude right here is ready to grapple. Don't let his fierce, competitive stare fool you. He's a supportive and friendly instructor who loves BJJ and serious workouts.

Keith Wittenstein



Began training jiujitsu in 1997 under Renzo Gracie. In addition to teaching BJJ, I taught yoga for many years in New York and currently lead seminars nationally and internationally for CrossFit. I love training jiujitsu because there are few places where you will be as present and in the moment as when you are grappling.
