In the words of Sensei Angelo

Karate has always been a part of my family and lifestyle. I started practicing as a young boy, never imagining the wonderful impact it would have on my life. After 1 year of training karate I was bullied by a bigger kid, he pushed me into a corner and left me with no option but to defend myself. My mind went blank but my body reacted, before I knew it the bully was on the ground. Ever since that day my karate training took a different meaning; mental and physical discipline. Karate formed the foundation of my beliefs, hard work and discipline can accomplish anything, which lead me to graduate with honors from UTA with an engineer degree. Now my goal is to pass down my knowledge to future karatekas.
