“After I graduated college, I decided, the most effective way to help others was through the martial arts practice that had helped me so much. I started this practice to strengthen my will and help my growth in being a more compassionate, driven, and focused person. I wanted to do this for myself so I could better help future clients as a counselor. It turned out that becoming an instructor was really what I wanted to do and how I wanted to help heal and empower others.
