Jeff began practicing Jujitsu under Sean McBroom (7th Degree) in 2007. As a former certified ACE personal trainer Jeff found that Jujitsu was an excellent way to improve physically and mentally. Jeff is a firm believer that Jujitsu will improve many other aspects of your life. Jeff was promoted to 4th degree black belt by Sean McBroom in 2019 and has been practicing Jujitsu since 2007. Holding a Masters degree in Education, teaching Jujitsu is something that Jeff enjoys and considers himself a forever student. To improve his understanding in the connection of grappling and throwing Jeff is also a student of Bill McElhaney, the Jiu-Jitsu Academy's Senior Judo Instructor. Jeff has competed in local Jujitsu, submission only and Judo tournaments but currently enjoys helping students with their goals for self-improvement or competition through training. Jeff says that "breaking down throws, positions and submissions to the smallest detail will improve your skill set. Getting an opponent to submit is the goal, but understanding all the components needed that lead up to the submission is key. Watching students grow and develop in striking, throwing and grappling truly brings me joy and I'm honored to be a part of that."
Bill is a Nidan (Judo 2nd degree black belt) with over 25 years of Judo training and competition experience. He has been practicing Judo since age 10, beginning in 1975 under Sensei Edwin Takemori, Shichidan (Judo 7th degree black belt). Competing as a junior and senior level competitor, he quickly advanced and was very successful in many DC local, regional, and national level judo competitions including multiple Jr. Olympics and Jr. National competitions. After taking a break for college, career and starting a family, he returned to Judo in 2005 to train with Sensei Marshall Coffman, Godan (Judo 5th degree black belt) at the Budokan Judo Club in Chesapeake Beach, Maryland. Since then he has been very active with regular training and coaching of students, hoping to provide them the same benefits and opportunities that dedicated coaches and the sport of Judo afforded him.

Beau began studying taekwondo in Southern Maryland during the early 1990s. In 1998 he was introduced to jujitsu by Sean McBroom, from whom he subsequently received a black belt in the early 2000s. Beau also competed in numerous amateur AAU jujitsu and judo tournaments as part of the Jujitsu Academy's competition team, which won several state and national championships. After receiving a black belt, Beau began teaching and coaching at the Academy's initial location in Bryan's Road. In 2006 Beau represented the Academy in its first professional cage match, traveling to Redding, California and defeating his opponent by TKO in the second round. Since then, Beau has primarily taught and trained on Saturdays, while attending the occasional day class or black belt test. He has received subsequent promotions to 5th degree (Godan) under Sean McBroom, although he considers himself to be an "expert beginner" and prefers to focus on basic techniques.
