Our School

Our mission is to improve the quality of life for as many people as possible through the martial arts!

We teach Kajukenbo, America’s first mixed martial art! We are constantly improving our curriculum, teaching methods, and facility to give you and your family the best training possible.

We also stay away from the egotistical, we know there is always something more to learn, and encourage our students to do whatever it takes to grow through the martial arts.


Our juniors program is for pre-teens. We teach them the same material as our adult class and prepare them for the real world!

4S Ranch Kids Karate Activities

We’re more than just a karate school. We’re a place to hang out and have fun… we’re a karate family.


What makes your 4S Ranch Kids Karate program different?

Our 4S Ranch martial arts school offers many events for your family to enjoy. We believe that if you are going to grow through the martial arts, our school has to be like another home.


Weapon seminars, dodgeball, nerf shooters, laser tag, Easter egg hunts, St. Patrick’s Day treasure hunts, Turkey Hunts, birthday parties, family classes, self-defense seminars, bully proofing seminars.

Do you charge for your activities?

It’s hard to walk very far without spending extra on your kids to give them the best experience life has to offer. That’s why our 4S Ranch kids karate program offers events every month that are free for your family.

So anyone can learn a weapon?

We don’t believe in charging extra to learn a martial arts weapon. Our demo team learns advanced weapons without paying extra. Our basic staff and nunchuck forms are taught monthly. Special weapon seminars happen as well, we just ask you pay for the weapon to participate.

Who supervises your 4S Ranch Kids Martial Arts Events?

Our instructors love teaching and interacting with students. So they facilitate and run all our events. Our head instructors are all CPR/First Aid certified, and all started out as students at our school. We love knowing that the 4S Ranch kids we first taught run all our martial arts events.

Can anyone sign up for events?

Actually yes you can. We wanted to make our events open to everyone. Because of this, you can sign up through our app, even if you are not a student at our school. It also makes it easy if you are invited by a friend, check out our app below. We offer special promotions, summer camps, and all our curriculum.

What makes our Karate school in 4S Ranch Different?

We truly believe our 4S Ranch Karate school has the best instructors, facility, and community for you to grow and feel welcome in the martial arts. West Coast Martial Arts Academy founded by Master Giuseppe Aliotta, who runs the Encinitas location. He has trained in Tae Kwon Do, Kung-fu, and more. In other words, the fighting arts are his life. Our 4S Ranch karate school started out with 5 black belt instructors, and although the black belts have changed, the quality has remained the same. Ready to get started? Firstly, fill out the form above. We will contact you soon!

What does our martial arts school teach?

The art we teach is Kajukenbo, a self defense based art for the streets. Our sign on our building says Karate in 4S Ranch, but our system was actually America’s first mixed martial arts! It combined Karate, judo, jiu-jitsu, Okinawan Kenpo, Chinese and Western boxing. As a result, we focus on real martial arts, not just showy acrobatics or dancing. That means the self-defense techniques are meant to be used for life or death, not necessarily in a ring.

That doesn’t mean we don’t spar of course, but we want our students to gain the benefits of training from an actual martial arts system. Some schools prioritize character development over martial arts, we believe martial arts teaches character! I am sure you have some seen martial arts schools in 4S Ranch like this.
