Jon is an awesome teacher. This man really understands wrestling and is very knowledge and passionate. Couldn’t recommend this place enough. He’s a great coach and a even better person.

Bettie is happy here. She’s been training with Jon for a few months. We’ve known Jon for years. He has been there for our family both in regard to wrestling and our personal life. Which we did not expect from a Coach. Jon has taken Bettie to other gyms like Top Team to allow her to gain knowledge from other coaches and wrestlers. His main objective for Bettie and wrestlers are to have access to mats and to provide a place these kids can call home. Home away from home if you will. Screenshot this, do whatever you need to do. It ain’t changing.

Mantis Wrestling (Mantis Sports Wrestling) is exceptional. Every coach is knowledgeable, personable, and fully invested — these guys truly live and breathe the sport. Head Coach Anthony is world-class, and Coach Adrian is outstanding. They make everyone better: experienced wrestlers reach the next level, and beginners are built the right way. In just two months, my 8-year-old son fell in love with wrestling, and that says everything about the culture here. The coaching, the kids, and the environment are top-tier. Best decision I’ve ever made for my son

I've been training with the coaches here for 4 years now. I highly recommend the wrestling instruction here for both kids and adults. The wrestling game I've built up thanks to Coach Anthony and Coach Jon has come in plenty handy in my MMA and grappling competitions. The instructors are friendly, knowledgeable, and highly passionate.
