David Nygren

Muay-Thai Level IV Instructor

My goal as a Muay-Thai instructor is to make sure that everyone in my class utilizes proper form, gets a great workout, and has fun doing it. I believe that if you learn Muay-Thai techniques correctly from the start, you will have a solid fundamental base that will follow you all through your martial arts training. The techniques that I have learned over the years have given me the confidence to be proud of who I am and what I have accomplished.

With this knowledge and skill set you will know more than the average person on the street. That being said, it is extremely important to me to instill confidence, not arrogance, in my students.

Always be prepared to work hard, have fun, and leave with a smile.

– I am trained in Muay-Thai Kickboxing and Boxing.
– I have been training at Gorilla Combat since 2006 and teaching since 2008.
– I have trained in Brazilian Jiu-jitsu and currently am a blue belt.

Juan Morales

Boxing Instructor / Coach

I have competed and coached in Mexico and the US for the last 12 years. One of my favorite things about sparring is testing one’s offensive and defensive skills. After every session you leave the ring with new insights and goals.
