What Our Students Say
Hear from our community about how training at our academy has impacted their lives.
Shelly Dillinger
"I went to Cornerstone, not knowing anything about Jiu Jitzu, except that I wanted to learn self-defense and a way to stay in shape as a 47 year-old female getting older. I wanted a whole-body workout that would serve a functional purpose, besides just weight-training at a gym. What I found was way beyond my expectations because this facility and its coaches, Rachel and Tom, welcome you to their family with open arms. Besides their expertise in Jiu Jitzu, they promote a co-ed atmosphere, with structure, that lends itself to the purpose I was looking for, and they make it so fun! The quality of the membership reflects the great spirit of the coaches!! Their patience and dedication to sharing their expertise with beginners and advanced alike has inspired me so much because I know I can meet my goals without hesitation. I will never feel like I'm dragging my butt to a workout, but excited to go see the family and build strength, endurance and character without even noticing because we are having so much fun in a disciplined, inviting and dedicated atmosphere. Surround yourself with great people, and you yourself will become great and/or remain great!! Iron sharpens iron. So grateful I signed up! Thank you, Cornerstone!"
Ivan Baublitz
"Rachel and Tom are amazing! I have a 6 year old in the class and Coach Rachel is enthusiastic and nurturing while encouraging. A great mix to have when teaching a sport like this. Highly recommend and a clean and respectful establishment as well!"
Alexander Mcnall
"Not only are Tom and Rachel amazing teachers, but they are amazing people. The culture here is welcoming and everyone supports each other. Egos are left at the door and everyone works to make each other better. You will be welcomed with open arms and will find a second family."
Matthew Jefferson
"I was all-in after my first class back in Fall 2020. I only wish I started sooner! Great environment, great people, at a great value. 10/10, would recommend to anyone wanting to take up BJJ."
