My son has loved it so much. He had to step away for a little bit for a procedure and he missed it so much. The instructors are amazing and the best part is they want their students to learn the foundations. They do not just give away belts. They want to make sure they are ready for it. Nothing but positive things to say. We love it.

Retro Sport is a hidden gem! A friend recommended it for tumbling but my boys immediately wanted to sign up for karate. We’ve done tumbling a couple other places and weren’t thrilled in the past. RSK has been absolutely fabulous and very affordable. We’ve LOVED the instructors and staff. They are all seriously so kind and patient! Their joy is contagious. We’ve been very happy with the amount of attention, technique and fun in their classes.

We've been attending RSK for several years now. Such a great studio with friendly instructors and staff! Studios are clean and the curriculum is great!
