Thatch not only shaped Aaron’s fighting style but influenced his philosophy of fighting. It was under Clarence Thatch that Aaron began to analyze fighting, breaking it down move-by-move. Only then was Aaron able to see the beauty and art of fighting. Aaron said of Thatch, “Clarence was such a student of the fight game, he knew what technique you were going to throw at him before you did.”
After a successful career as a fighter, Aaron has found great joy training competitive and non-competitive athletes, passing on his experience. Since the year 2000, Aaron has trained many local, regional and national champions. Coach Aaron has trained at Edge MMA for almost ten years and is happy to be teaching the Muay Thai and Cardio Kickboxing classes.
