About Us

Greg Bartman - Head Instructor/Owner

Greg Bartman has been training and teaching Gracie Jiu-Jitsu, Self-Defense, and Muay Thai Kickboxing for over 24 years total, beginning substantially in 1994.

He welcomes all students regardless of experience or athletic ability and emphasizes training in a safe environment for long term goals. He aims to demonstrate clear instruction and a thoughtful understanding of his student's needs.

Professor Greg is a certified Instructor of Black Belt rank with Second Degree (2018) under Grand Master Relson Gracie, who is recognized as the world's best self-defense instructor. Relson's core technique was handed down directly from Helio Gracie. Greg is known for his technical understanding of the important details underlying the Gracie self-defense techniques as well as the broader concepts. He is past due to test for his Third Degree because of pandemic restrictions.

Greg has a strong interest in the practical application of self-defense, and recognizes the positive impact that conquering physical and mental challenges can have on increasing an individual's self-confidence and in turn the ability to defend themselves.

His training has also involved Judo, Wrestling, Aikido, Jeet Kune Do, Tae Kwon Do, Boxing, and Kendo. His students have included state and county police, FBI, CIA, US military, bouncers, correctional officers, cage fighters, doctors, attorneys, stay-at-home parents, girl scouts, kids, teens, and adults of all ages, fitness levels, and professions.

Tori Garten - Instructor

Tori began training self-defense based on Gracie Brazilian Jiu-Jitsu with Greg Bartman in 2006. She is a certified instructor and Black Belt under Greg Bartman and Grand Master Relson Gracie. She is currently the highest ranked woman under GM Relson Gracie.

Tori co-instructs the KickAss Women's Class, self-defense seminars and workshops, the Kids' class, and assists new students in the Gracie Jiu-Jitsu and Self-Defense classes as they become acclimated to the art. She is also available for private lessons

She is active in the national women's jiu-jitsu community, and feels everyone, regardless of age, strength or athletic ability should have the opportunity to learn to defend themselves in a safe and welcoming environment while learning the beautiful art of Jiu-Jitsu. 

She has a strong interest in the practical application of self-defense, and recognizes the positive impact that conquering physical, mental and at times emotional challenges can have on increasing a woman's self-confidence. She has also seen the positive impact the Kid's class has on kids who come in shy and unsure of themselves, and leave with greater confidence and gumption.

Her instructional specialties include:
  • Self-Defense (including against weapon attacks)
  • Relson Gracie Brazilian Jiu-Jitsu
  • Gracie Survival Tactics (GST) Level 1 and Level II certified
  • Working with women with previous assault backgrounds
Tori also has cleared background checks through the US Army for working with children. She is certified in Advanced First Aid, AED and CPR, as well as trained for the Community Emergency Response Team (CERT). Additionally, Tori is a graduate of Bowdoin College.

If you are not sure if self-defense training is for you, read Tori's article "In-defense of Self" on the impact Brazilian jiu-jitsu self-defense can have on several aspects of life. 

Sometimes walking in the door the first time is the toughest step on the journey. The return on that first step is you'll know more, feel stronger, more in control and more powerful when you walk out after class.
