Reaction MMA is a mixed martial arts school led by Professor Rob Nickerson III.  Located not far from Lexington's Fayette Mall, Reaction sits in an industrial park directly off Nicholasville Rd. just a short drive past Brannon Crossing in Nicholasville, KY.

We are a serious mixed martial arts school where both adults and kids learn and train effective fight skills in Brazilian Jiu-Jitsu, Muay Thai, wrestling, boxing and MMA. Not all of our fighters compete, but many of them do. Not everyone who trains competes but will learn the same effective skills for real world self defense, as well improve physical conditioning. Reaction MMA has some of the most successful and top ranked pro and amateur MMA fighters in the state of Kentucky.

We also have fighters who compete in various grappling competitions ( NAGA, Grappler’s Quest, OGC, EGO), Muay Thai and kickboxing events ( IKF ), and Boxing competitions (AAU, Golden Gloves, Silver Gloves). Reaction MMA has produced fighters that train in many well-established organizations such as King of the Cage, XFC, RFA, UFC, and a plethora of local shows.




Reaction MMA is fortunate to have a wide variety of individuals on the mat on a daily basis; and that includes a number of upper-ranked instructors/coaches.

Brown belt coaches Daniel Hunt and Chad Talkington also work side-by-side with Prof. Nickerson to assist with instruction.
