This place is a JOKE!! Before I scheduled and payed for a 3-day trial class, I spoke with them over text to confirm this is what I wanted. They promised to be open and day of my class there was no one there. They’re advertising they’re open but they don’t want to do their job. I called them and spoke with the useless phone lady and she wouldn’t give out simple information. I waited outside for 20 min and nothing. A week later I called again and same useless lady promised me another call back which she’s a liar. I’m done. I called my bank to request the refund. Don’t bother wasting your time with this place. They are not serious about business here.

This is now the 4th day that I come during listed business hours to become a member and no one is here. Called the number and the answering service can not provide any information other than taking messages that no one responds to. Maybe hours changed during Covid? Really wish they would update instead of wasting potential members time.

This place is great for kids but should change the thermal gun because being touched by it with many germs is disgusting. Just cause it doesn’t read, there’s many more products that can be reading your temperature correctly. I know this place got money like that as if I haven’t heard how much people are paying.

Amazing place to train with experienced staff teaching a curriculum for rank testing. Training here is amazing for a place of respect and learning the Thai culture. Great place for beginners and the competition team.

I've been taking classes at Double Dose since September and I absolutely love it. Their staff is incredible and they always do their best to help build you up in any way they can. They make sure the curriculum is easy to follow and is always fun. The staff will always make sure to teach you clean and crisp techniques which makes it easier to learn later on. I absolutely recommend this gym to anyone of any age looking to get fit and learn self defense. You won't regret it!

When I was looking for a good martial art to learn and started asking around, one of my work colleagues told me about Double Dose Muay Thai. He said it was a great place and that I should check it out. It was the best recommendation I ever received. I was hooked from the moment I stepped in and spoke to Kru Marcos for my introductory session.I've been at the gym for a year and a half now. I really love the focus on the traditional instruction and rituals. Emphasis is placed on performing techniques correctly and learning the Thai words for them. We even learn self-street defense, which are practical applications for use in real situations that occur today. And they work!What I love the most is the encouragement that comes from fellow students, our instructors, and sometimes from the parents and family who watch us. We have a comradery that you just won't find in any other gym! We work hard but have fun at the same time. I recently started learning Krabi Krabong (Thai sword fighting) with Ajarn Bryan - and we are having a blast! There's so much energy and excitement from Ajarn Bryan. You can feel his enthusiasm as it it radiates from him into the classroom. He takes pride in the quality of our instruction and works very hard along with all our instructors to ensure we receive the best from them. Not only that, he brings in world class fighters and instructors to hold seminars at the school so we can broaden our knowledge of Muay Thai and give us some self help. For example, a couple of months ago Ajarn Bryan brought in Grand Master Chai - and we had the wonderful opportunity to spend four hours with this great man who brought Muay Thai to America.I am proud to be part of such a great gym with world class instructors who care about their students. If you're looking for a great place to learn a centuries old martial art, then look no further -- this is the place to go!

Muay Thai has changed my life dramatically and if it wasn't for Arjarn Bryan and the awesome instructors at Double Dose Muay Thai, I don't know where I would be. 40 lbs. heavier that's for sure! If your looking for a fun, intense workout, and to study one of the best martial arts out there, come check out Double Dose Muay Thai!

Double Dose Muay Thai is an awesome gym. They stress discipline, respect, and a hard work ethic in every class. I'm glad I started training there after High School, because it helped me grow up, but I wish I would've started sooner!
