Who We Are

Foster Ehrie

HEAD KIDS COACH

-BJJ Blue Belt-
-4 Years High School Wrestling-

Foster's Bio

Foster began training Jiu-Jitsu at age 10.   After focusing on wrestling for 4 seasons in High School, he restarted BJJ and joined the Pedigo Submission Fighting team in 2020.
He made a strong addition to Triangle’s new & growing training room, but truly stood out when he began assisting with the Kid’s Classes.
Foster has a genuine passion and heart for children, and a natural ability to relate to, teach, and mentor young athletes.

After two years of training and teaching as an Assistant Coach, Foster became the Head Coach of our Kid’s Jiu-Jitsu Program.

“When I first started coaching, I had no idea how impactful this career could be.   Not just teaching Jiu-Jitsu & Wrestling, but imparting life lessons, good manners, and – most importantly – helping these kids understand what can come from hard work and discipline.   Every day I come to the gym with an immense sense of pride and gratitude for this opportunity!”

Justin's Bio

Justin began training in Ohio in 2014, under the Ribeiro Jiu-Jitsu Association.  After receiving his Brown Belt, Justin and his wife Christy relocated to Franklin, and joined the Pedigo Submission Fighting team.
He has been a dedicated part of our training room since shortly after Triangle Academy opened, and brings a wealth of experience to the Kids Jiu-Jitsu Program as a Senior Coach.

“Jiu-Jitsu is a great way to stay in shape, gain self-confidence, and improve in so many ways – I love it because it is so FUN!! My favorite part of being a coach is seeing other people’s growth. Knowing that I can help kids learn to handle a bullying situation especially is a great feeling.”
