I attended the Jiu Jitsu and Muay Thai classes during my stay. All staff, instructors, and students were very welcoming, friendly, and respectful. Of the classes I took, Pedro and Joel were the instructors and you can immediately tell they both have extensive experience. Their instruction, approach, knowledge, and interaction are all reasons for anyone to come in and experience this gym. If you are looking for a place to train permanently or if you are just in town and want to get good quality work in, you can't go wrong at Sierra MMA. Thank you Pedro for the hospitality, I will definitely be back in during my next visit to Utah.

It's in a very industrial part of Orem, so even if you think your GPS is leading you astray, it's probably not.

A lot of the people in the beginner classes I tried weren't exactly beginners, but everyone seemed super willing to try to explain the moves.

My son (7) is enrolled in this school. Before joining BIMA my son was enrolled in another school…read more So, I have experience with these type of schools. My son started going to BIMA in Feb 2019. At BIMA, they provide quality education that not only focuses on martial art techniques, but also discipline and respect (for the instructors, the facility, the experience, and one another). The instructors are great with kids. They are firm, but gentle. They seem to really care about each student's success. And, as a result, BIMA kids are really engaged in their education. When my son registered in a tournament, one of the coaches went to the tournament to mentor him, which was really awesome. When I asked my son what he loves about BIMA he said he loves the instructors and learning all the cool techniques. If you are looking for a martial arts school for your kid, look no further. BIMA is awesome!

Update: this is not an ethical business. This gym tricked my husband into signing a contract. He…read morewas lied to by Mike the owner and Heather the manager. My husband went to this gym with a Groupon in Spring 2025, a contract was proposed and my husband declined entering a contract. My husband does not do contracts with gyms. My husband proposed a month-to-month contract to Heather and Mike. Heather asked Mike if that was okay, and Mike said that it was. Heather then provided my husband with a document and explained it was to accept gym rules and waive liability, which he signed. My husband needed to cancel his membership in December 2025 and requested that through the billing department email which is just Heather. Since the payments didn't stop, he attempted to resume going to this gym two or three months later, but this was during the period when this gym had no physical operation. He showed up two or three times at the new address and didn't find any gym there. This was a very distressing and confusing situation for him. I tried contacting the billing department, but there is no billing department, it is just an email address and they don't take calls. My husband had been trying to get ahold of the "billing department" as well with no luck. I explained the whole story about what happened in an email to the "billing department." Heather said that she would cancel the contract but that this would just go to collections. In another email, Mike told my husband to "tell your wife to f*** off." Today, we received that bill from collections. My husband never understood he was signing an annual contract and was explicitly told by Mike that he could do a month-to-month arrangement, and Heather lied to him about what he was signing. After all this happened, I looked back in time at Yelp reviews and found that this business has been doing shady and dishonest behavior like this for at least a decade.
