“This class made me stronger and gave me more endurance. Something I will need when I go into the ARMY. The class made me a skilled fighter that one day could save my life or the life of others. I thank David for all the skills he has passed on to me and all the lessons in life he has taught me. I am now a greater person then I ever was.” 
Jeff S.

Student

“David was not only an excellent coach for my fight debut, which I won in the first round, but his integrity and trust earned my friendship for the long haul. He was an incredible coach and teacher in my climb through the complicated field of MMA. He brought a sense of realism and understanding to every class. His strengths and proficiencies brought me from a basic level of understanding to amateur fighting status in a short year.”

David is a high skilled and disciplined martial arts practioner. I recommend all parties interested in learning the mental and physical aspects of martial arts to experience the training of Mr. Demetroulis.”
