Coach Ben has trained military, law enforcement, and taught self defense across the globe. While teaching in Taiwan he decided to stop by Thailand and fell in love with Muay Thai, also known as the powerful "Art of 8 Limbs". He came back the the United States committed to finding the best Muay Thai coach on the continent, and became the life long student and friend of Muay Thai legend and UFC coach Jongsanan Fairtex, also known as the "Woodenman".

The coaches here are incredibly great instructors, particularly for beginners like me. They have motivated me to keep coming back to learn more, get a great workout, and have fun. The encouragement from them and other class members have burned an enthusiasm in me like nothing I’ve ever experienced before.

Robbinson Galvez (Currently #1 ranked welterweight in the world)

Long story short: PHAS3 is the best Kickboxing/Muay Thai school in the area. When I first came here in 2017, I weighed roughly 210 lbs. And now I walk around and fight at 147 lbs. Long story: I have been coming to PHAS3 for a little over a year now and from the minute I walked in I knew this was different. My story is different then most as i walked in looking for fights and looking to actively compete. I didn't hide that one bit. It was probably the first thing I said when I met my coach Ben Brown. I was very well attended when I walked in and had a great authentic conversation with Coach Ben about my goals. Once I started training i felt right at home. I didn't know anyone I am not from this area but once I stepped on the mat I felt like I belonged already and was hooked before I even threw a punch on the mat. At PHAS3 whether you're looking to get a great workout or train with top notch competitors and Champions it is the right gym for you. You see the diversity of goals once you walk in and see everyone doing class. Another special thing about PHAS3 is that everyone trains together. Male, female, Young , "Old", competitors, Champions etc. There is no ego of I'm better than anyone else. High level competitors will pair up with new people and give you the attention you need. The coaches are amazing. Head Coach Ben Brown has changed my life. I was a sloppy unsuccessful MMA fighter when I walked in and coach turned me into the fighter I am now and am still becoming. Coach Ben produces Winners and Champions this a great camp to fight out of. The other coaches are very helpful and teach amazing classes as well. All of them also teach kids classes which makes the kids classes top notch as well. If you take one class I'm sure you will share the love that I have for PHAS3. Try it it could change your life.

My daughter and I have been training at PHAS3 for less than a year. In that time the biggest growth that we have seen isn’t something physical. It’s a deeper personal growth. My daughter Evie has learned how to lose. Like many kids her age, outside of the gym a lot of he experience is learning to do something right. From the first game of “Laser Rope” at the end of class she had to learn to win, learn to lose, and learn to forgive herself so she could do her bees in the very next game. PHAS3 is Awesome!
