I am a real person writing a real review… John is the coach/instructor of REV Combat. I purchased a Groupon and wanted to try it out. Probably the best Groupon deal I ever purchased and I have been in his class for almost two months. Great coach with structured lessons that push you to get better and great guy to hang with outside of class. Also, everyone I roll with has so much respect for each other and are great training partners. Come try it out.
