Client Testimonials

"My children have been coming to the SDSS Martial Arts Studio in Wilton for years. The studio and its staff have always been remarkable especially through COVID. It has been one of the only places I continued to send my children knowing how cautious and safe they were."
Lauren G - SDSS Wilton Parent
"Great martial arts school all around. Teaches kids to be the best they can be not just in Kung Fu but in everything they do."
Sean F - SDSS newtown Parent
"SDSS changed my life! It taught me discipline, strength, and confidence. I highly recommend it! Sifu William and Sifu Travis are the most accommodating people I have met, as well as the friendliest. They taught me highly effective moves to use in a street situation, and extreme high intensity workouts. SDSS has changed my life in so many ways, and I am confident that it will do the same to you."
