Our Students Say...

Looking strong and being strong are two different things. That’s what you learn at the dojo. With bad people on the streets, I highly recommend to join USSD SF and learn the intricacies of Self defense and karate in its purest form.

Sensei Collins is an excellent instructor and an even better mentor to all of his young students. Having grown up around martial arts myself, I am continually impressed and thankful that my kids are part of this program.
