Welcome to The Best Martial Arts Program in San Diego

Hi, my name is Joe Carroll, and I’m very PROUD that hundreds of families all over the San Diego area are singing the praises of our martial arts program and telling their friends and neighbors how much of a positive impact it’s having on their lives.

4S Karate has been a landmark of San Diego for many great years!
Get started now and find out how you can be healthier, happier and more confident with 4S Karate training!
Our members tell us that they feel our school is more of an institution of self-improvement, physically and mentally, rather than “just” a gym or some “activity”.
I pride myself on helping our adult members safely build muscle, quickly burn fat, gain flexibility and release stress in a FUN, positive and injury free environment – with our martial arts for adults program! And for the children, parents all over the San Diego area give my children’s martial arts program credit for increasing their child’s ability to focus, building their self-esteem and igniting a passion for self improvement they never would have expected.
Although many people think the martial arts are just about fighting, the truth is that the physical “kicking and punching” are really just the “tools” that I use to teach the more important, and MUCH more valuable lessons about “yourself”.
When you train in our San Diego martial arts programs (which also serves 4S Ranch, Rancho Bernardo, Carmel Valley, Rancho Santa Fe, and Carmel Mountain Ranch), you take advantage of the best self-improvement system in the world.
Through the practice of physical self-defense skills, you will follow a blueprint for a successful life based on discipline, focus, and perseverance. Please, take a few moments to browse this website, get familiar with us, then, take me up on my “No Strings Attached” offer, and see the benefits of my San Diego martial arts programs for yourself…..FOR FREE!!
