Can Anyone Recommend a Martial Arts Gym that Teaches Kickboxing?

Nothing against Muay Thai, but I would like to learn Kickboxing. Within the Inner Loop in the Northside, Medical Center, or Heights Area that has Kickboxing classes during the morning or day. I've seen most striking classes are in the afternoon or night. Not trying to be competitive, just want to learn some self defense and be fitter. If anyone recommends a personal coach, that would be great too.
