I've been training at SOS GYM coming up on five years, and I can't say enough about the incredible experience! Under the guidance of owner Nathan Fitch, whose decades of expertise in BJJ and Muay Thai shine through in every class, I've grown tremendously in both skill and confidence. The welcoming atmosphere, diverse class offerings, and top-notch instruction make this gym a true gem in Northern Kentucky. Whether you're a beginner or a seasoned martial artist, SOS GYM is the perfect place to train and connect with a supportive community along with dedicated professional instruction.

Eight years ago I walked into SOS with the desire to try something new and never left. Prior to SOS, I had some martial arts training but, you find out quickly how much more you have left to learn. No matter my level of fitness or training, SOS has always been able to help me achieve my goals. The Coaches are passionate about what they do and teach and give you the confidence to achieve whatever you put your mind to. I couldn’t recommend SOS enough!

I’ve trained under Son of Siam for over 15 years. Nathan Fitch is the best instructor I have ever trained under, his knowledge and teaching ability is second to none. I would highly recommend, you will not be disappointed!
