This gym feels like a family! I always sing "rolling with my homies" to myself as I'm driving there…read more As a woman, I've always felt super safe and respected even though BJJ by its nature is all physical contact. I've been here for a year now and feel so confident and strong. Also, I love all the instructors' laid back sense of humor combined with serious instruction. Love you guys!

Take this review how you want, just know that I have no reason to lie about this place. Johnny Buck…read more(main instructor/owner the way he explained it) makes fun of the mentally ill with a lot of maliciousness. 7 months into my BJJ journey and taking my training very seriously; I saw a student go up to Johnny and say (referring to one of the mentally Ill students who would train with us) "I was worried about hurting him" in which Johnny responded with "Oh no, they're really strong, they can handle a lot, and uh don't worry if you hurt em because they're not even human so..." Racism is prevalent here, don't be fooled by their kindness at first. Johnny used to call me mutt before I confronted him on that. There's plenty of cops that go to this gym so if the "leader" is encouraging making fun of mentally ill people and racism then you have a cycle that will continue throughout the community. This "gym" pushes a 12 month commitment for new members. They speak under their breath about you here if you don't submit to their culture or their way of thinking. It's almost like a cult in a way. The main reason why I wrote this review is because I felt it was my civic duty to let anybody who's innocently trying to learn self defense to protect others, are not taken advantage of like I was. My advice to new and potential future customers is to please stay away from that place but if you do want to check it out then I suggest you listen to your gut, stay true to who you are, and if you believe in God stay close to him because this guy and his ilk aren't good people. -Message to Johnny: What you teach is a perversion of what real humans naturally feel. Real humans have empathy. You don't.

Stick with it and change sure will happen I have a bad military injury that I don't speak about to much but little by little and starting to do a bit better hopefully soon I will loose those extra pounds and maybe compete once again will see only time will tell. My little girl she is 7 yrs old and she can't wait to go to the gym everyday she's asking are we going today and I'm glad she feels comfortable there just shows the quality of mma coach we have at this gym.

Truly expected my son would be interested for about 6 months, maybe. 3yrs later and he is on the cusp of getting his black belt and has also started jujitsu.

Their curriculum is built around respect, focus, discipline, and courage. Olson's is and will be a large part of our lives. Thank you!

This place looks like any regular gym would. They got specific areas for whatever class you are…read moretaking. They let me borrow some gear for my first class. The person up front is very helpful and makes sure you have everything you need. The teacher I had made sure to demonstrate each move before letting the class practice the move. Them we were partnered up with another person in that class and we did that whole bit a couple times before planking. There is a locker room with bathrooms and showers. They have a schedule for adults that shows all the classes they'll have Monday through Saturday. They also have classes for kids and overall it's a great place to learn. I only give 4 out of 5 because it's my first gym and while it was great, I have nothing to compare it to. I definitely recommend.
