Corey Cottrell


began learning Muay Thai in the late 90's from Zennie Reynolds, a semi retired former heavy weight world champion who had a small martial arts school in Columbia, MO. He wanted to learn kickboxing for self defense, but soon fell in love with the sport and the many physical and emotional benefits that come from training Muay Thai. Recently, Corey as recently enrolled in Arjan Buck Grant's Muay Thai University continuing his decades long journey of self discovery and exploration through Muay Thai.

Corey teaches Muay Thai in the hopes of giving back to an art that has given him so much in terms of confidence, discipline, and a much needed skill to help navigate the world. He hopes to help each person with their unique goals and reasons for training.
