Professor Finnie McMahon

FinnieMcMahOwner and Instructor of the fast-growing BJJ martial arts academy in Ft.  Collins and a full-time second degree black belt instructor and mentor, Professor Finnie McMahon was first introduced to martial arts at the age of 10 through Kenpo Karate.

After kayak instructing for three years in Crested Butte, Finnie rediscovered his passion for martial arts and began training Brazilian Jiu-Jitsu in Santa Fe, New Mexico under the instruction of Professor Alberto Crane, a black belt under Vinicius Draculino Magaelhes.

In 2001, Finnie moved to Boulder and began studying under Professor Amal Easton, a Renzo Gracie Jiu-Jitsu black belt.  From there, he managed the Easton Brazilian Jiu-Jitsu Academy in Boulder for three years, while competing and training in BJJ and MMA.  He emerged quickly on the scene, snagging first place honors at the 2001 American International championships, and has since continued to make a name for himself in national and international top-name events.  McMahon’s success culminated at the 2009 Pan American championships in California where he won the gold medal in the Brown Belt division and was awarded his Black Belt on the podium by Professor Amal Easton.

Upon meeting Master Renzo Gracie for the first time in 2004, Finnie was so impressed with him that he travels to New York twice a year to train under Master Renzo and the RGA team. Because of this dedication, McMahon Brazilian Jiu-Jitsu is an official Renzo Gracie Jiu-Jitsu Affiliate school.

Professor Tessa McMahon

TessaMcMahThe owner of McMahon BJJ and one of the only female Jiu-Jitsu black belts in Colorado today, Tessa McMahon began her search for the most realistic form of self-defense as a senior at CU in 2001.  She found it at Easton Brazilian Jiu-Jitsu in Boulder, where she quickly flourished in the art of BJJ – Tessa McMahon was the first American woman to win the Pan-American gold medal for two consecutive years, and was ranked the #1 female in her weight class in 2005.

After graduating from college, Tessa became a middle school Spanish teacher, and taught for five years in Aurora, Co. During that time, she continued to train BJJ under Professor Amal Easton, and competed successfully in various BJJ tournaments around the world.

In 2004, Finnie and Tessa were married, and two years later, decided to dedicate their lives to BJJ through opening the McMahon Brazilian Jiu-Jitsu Academy in Fort Collins, Colorado.  While Tessa instructs women and men of all ages and abilities in Brazilian Jiu-Jitsu, she also helps run the Academy’s rapidly growing circle of boys and girls learning the finest art in self-defense technique.
