Mark Sweigart

BROWN BELT

Mark has been training Brazilian Jiu-Jitsu since 2010. On his first day of class, Mark was amazed at how smaller opponents, 70-80 lbs lighter, could control him with little effort, rendering his physical abilities useless. From that point on, Mark was hooked, training every chance he had.

Mark received his purple belt from his long time instructor Brian Fisher. Mark has experience in several other martial art disciplines as well, none of them attracting him in the way BJJ has. Beyond competing in Brazilian Jiu-Jitsu/Submission Grappling tournaments, Mark has also competed in Mixed Martial Arts. This has given him an understanding of how to adapt traditional Brazilian Jiu-Jitsu into MMA.

Mark is a Certified Strength and Conditioning Specialist, CSCS, through the National Strength and Conditioning Association, the leading sports performance institution in the country. Having received his Bachelor's Degree in Exercise Physiology from West Chester University, Mark has a deep understanding of the body's physiology and applies this knowledge to his martial arts instruction.
