He is constantly researching, testing and applying fitness and martial arts methods and techniques in order to improve his skills and the skills of his students. Mark has an understanding of many systems that often surpasses that of the chosen masters of those systems. Anyone truly interested in the martial arts or fitness instruction should consider themselves fortunate for the opportunity to study with Mark Harrell."

"Any person who wants to learn martial arts should not miss the opportunity to train with Mark Harrell. His unique experience of over thirty-five years of in-depth knowledge and expertise in numerous martial art styles allows him to customize training for any private students. Unique among martial art instructors is Mark's teaching abilities and his step-by-step curriculum. His approach to learning is systematic and logical. He instills a firm foundation of fundamentals upon which any student can advance. Mark's honesty, sincerity and straight-forward communication skills make training almost transparent. You absorb rather than memorize. At age fifty I had the honor of becoming the oldest person to achieve ranking in the martial art of Kali from the Harrell Academy. It was the most physically demanding, yet one of the most spiritually fulfilling accomplishments of my life. I could not have achieved this without Mark's patience, guidance and encouragement".

"Sifu Mark Harrell created a customized program to meet my training needs, using his extensive knowledge and experience of many martial arts systems. He cut through all the fluff to the core of training to fight and win. He combined various Filipino, Indonesian, and Chinese martial arts systems with a devastating mix of street boxing techniques to provide me with extremely effective and realistic training that I continue to build upon to this day. Sifu Harrell is the real thing, a true world class martial artist and fighter. He is a rare find in the martial arts community; he adds to his knowledge base constantly, can really do all the things he teaches and is an outstanding instructor. I highly recommend Sifu Harrell to anyone who is seeking serious applied knowledge and training in the martial arts, no matter what system in which the person may have interest".
