Even as a school of martial arts in Rancho Bernardo we offer way more than just our regular self defense classes. Our party services only require you to show up and add some decorations to match your party theme, allowing you to have a worry free day where you can sit and relax or even better, jump in on the fun yourself!

We offer a variety of different themed parties that have been voted best in San Diego, the first of which is our Kids Karate themed birthday party where our own expert martial arts instructors teach your kid the basics of being a ninja. From dodgeball to an exciting martial arts relay race, and even breaking boards, your party will be hopping around punching, kicking and having an absolute blast at your local martial arts school in Rancho Bernardo. https://www.4skarate.org/kids-karate-theme-party/

Our adult self-defense and kickboxing program is a combination of the self-defense techniques taught in Kajukenbo and kickboxing techniques taken from Erik Paulson’s STX Kickboxing program. It combines striking from boxing, Panatukan, Jun Fan Kickboxing, Savate, Taekwondo, and Muay Thai. We are the only school in 4S Ranch or Rancho Bernardo teaching this style.

STX kickboxing lets students learn to combine punch and kick techniques with their elbows and knees. Skills are pulled from each style to work in MM, kickboxing, or self-defense situations. Whether it’s using focus mitts, heavy bags, or drilling with a partner, students get a great workout and can really see a difference in their body and mind only after a few weeks.

This is a great class for dropping some pounds, making some new adult friends, and is appropriate for all skills levels.

Regardless of how big you are or what you may know, everyone who jumps on the mat wants to keep themselves and their loved one’s safe. You’ll learn techniques that will use your opponent’s strengths against redirecting your opponent’s force, especially if they’re bigger or stronger than you, and we’ll match you with a fighting style perfect for your unique speed and body type. With this level of training, you’ll feel limitless in no time!

Master Martial Artist Down The Street
Many 4S Ranch martial arts schools teach a version of Kajukenbo, but we have an edge. Our school has been in the same palace for 15 years, and we’ve done nothing but grow and expand our program. Our Encinitas location has our head instructor, Master Giuseppe Aliotta, just twenty minutes away! He comes in to teach martial arts seminars at our 4S Ranch location all year long. It’s fantastic to have access to someone with such a wealth of knowledge.

We have a firm belief that martial arts need to be rooted in being effective. That’s why once our kids reach a certain age, we try to incorporate as many realistic training modalities as possible. There is an aspect of martial arts that requires focus of mind while performing movements that are complex, but these moves aren’t always effective for fighting. We encourage our students to practice what they like, if they enjoy the performance aspects of training that’s great. But at the end of the day, what we teach daily in classes needs to be effective for fighting. If you’re not getting better at self-defense while you are training, then how are you supposed to gain real confidence?

Turn Our Mat Into A Warzone And Enjoy The Benefits Of Our Indoor Nerf Party:
Tons of Game Options
There’s a variety of games to choose from that make this party a hit with 4s Ranch kids. Karate games are fun and all but let’s turn up the heat with some nerf games. Some kids are less aggressive and may just enjoy using our bags for target practice. Other kids enjoy the team work of a good old fashioned capture the flag game. There’s always a last man standing or free for all options as well.

Custom Terrain
With our selection of over 30 foam blocks, there is a limitless amount of customization for your battlefield. If kids start to get bored with a certain setup it’s as easy as changing a map in a videogame to bring the excitement back! Why drive around 4S Ranch or Rancho Bernardo when we can just rearrange a few blocks while your kids have a water break?



Use Ours or Bring Your Own Guns
We have a wide selection of pistols and machine guns for the kids to choose from with a nice big bag of 500 bullets. If that isn’t your jam you can always bring your own guns and use them instead. We do recommend if your gun uses the same bullets as ours you don’t bother bringing your own bullets. We have plenty to spare.

Easy Cleanup
No wandering around looking for bullets in 4S Ranch. Our martial arts school is the perfect place to have your battle and not fight over whose bullet was whose.

Create Your Own Fortress
Kids love being able to take a corner of the school and turn it into their own nerf fortress. Kids are welcome to take a few minutes and design their own barricades, walls, and cover. Aside from our foam blocks the kids can use our base bags, kick shields, hand pads, crash pads, and judo mats to make their own walls and cover. It can be just as much fun to plan your defense as it is to shoot at each other.

Safety First
There can be a lot of accidents that happen in nerf wars. Kids can get shot in the eye or have head on collisions because they are distracted by enemy fire. We make sure our birthday parties are safe for your kids. We provide eye protection so your kids don’t end up being a pirate for their next Halloween. We also avoid many injuries with our foam terrain and padded mats. You can relax and enjoy watching the party without worrying someone’s going to lose an eye.

“My son wanted to celebrate his 8th birthday at his favorite place outside of school, West Coast Martial Arts (WCMA). We arranged with Will and his incredible team to throw an epic Nerf battle party for my son and his close friends. WCMA staff were on time, super helpful and interacted with the kids amazingly. Parents were able to relax as their kids blew off their energy and had fun. My son rated his party, “10 out of 10!” thanks to the dedicated, passionate team at West Coast Martial Arts. We had a day that we will remember forever.”

-Justin Umpierre
