CALI COMBAT SYSTEMS

Real feedback from real students, guest instructors, and visiting practitioners, in their own words.

★★★★★

5 out of 5 from 37 five star reviews across Google, Yelp, Alignable, and Facebook

 

Every single review Cali Combat Systems has ever received is five stars. Thirty seven people, from first time students to decades long martial artists, PFS certified instructors, seminar guests, and even a synagogue that brought Sifu Jeramiah in to teach a six week Krav Maga course, have taken the time to say the same thing in different words: the training here is real, the instruction is exceptional, and it works.

​

Students consistently point to three things. First, the depth of Sifu Jeramiah's background: a lifetime spent training and cross referencing striking, grappling, and weapons systems rather than staying locked into one style. Second, how well that depth translates into teaching: patient, clear, and able to meet a student wherever they are, whether that is a sixty year old taking their first class or a ten year veteran of another art. Third, the realism of the material itself: the techniques are built for the street, not the tournament mat, and reviewers who have been in actual physical confrontations before say the training holds up.

​

Below you will find a summary of what is actually taught at Cali Combat Systems, followed by every review in full, exactly as it was written.

What We Teach – The CCS Phase Method

Cali Combat Systems is built around a single idea: a fighter needs to be dangerous everywhere a fight can go, standing at range, in the clinch, on the ground, and against a weapon. Rather than teaching one style in isolation, Sifu Jeramiah has cross trained across Jeet Kune Do, Kali-Silat, Israeli Krav Maga, and Combat JuJitsu, and built a single integrated curriculum around what actually works when the fight is real.

​

Students progress through the CCS Phase Method, heavily inspired by Guro Dan Inosanto's lineage, which trains students to seamlessly transition across different ranges of combat. The school calls its blended style "Filthy MMA," prioritizing practical technique over sport rules, with a simple motto: Bite. Fight. Escape to Safety.

​

The curriculum integrates four core systems that layer on top of one another as skill develops:

• Fight Rhythm Jeet Kune Do — Jeet Kune Do, Bruce Lee's original kickboxing and striking lineage, trained for timing, distance, and economy of motion.

• Kali-Silat Motion — Southeast Asian Martial Arts focused on practical stick, knife, and empty hand weapons training (Inosanto, Pekiti Tirsia, Silat, & more).

• First 2 Fight Retzev Combatives — Israeli Krav Maga, Rapid Assault Tactics, street proven, aggressive combatives designed to end real threats quickly.

• Integrated Ground Fighting Systems — Functional pressure tested Submission Grappling, Combat JuJitsu, and KinaMutai (asymmetric street grappling).

​

The goal of every class is Combat Flow — the ability to move seamlessly between ranges, weapons, and systems without resetting.

Customer Reviews: In Their Own Words

1. "Top notch training. Great for Learning self defense. Jeramiah is by far the best instructor in San Diego hands down. I refer everyone to train with him." -- Jose Avalos

2. "Training at CCS has helped me feel more confident and relaxed- not only in potentially physical situations, but in life. I (and others) can see the difference in how I react to stressful work or family situations. I feel I’m calmer and more confident." -- Jon Beyrer

3. "Cali Combat was just what I was looking for! I have studied martial arts for years but I wanted to supplement my experience with some combative/tactical skills and Jeremiah does just that. His program is a comprehensive, practical system that includes training in grappling, striking, and weapons. I am glad I found Cali Combat and I would highly recommend it to anyone interested in learning how to defend themselves in real-world situations." -- Daniel Hernandez"

4. "I've been training for about four months now and I have been quite impressed. What convinced me to stay was that my first class involved knife fighting. Next class, stick fighting; the class after that, how to throw someone to the ground and it goes on and on like that. Each class there is something new or reviewing something badass like flipping someone. This is very hands on martial arts street fight training. There are various techniques taught from various martial art styles. If you want to focus on a specific martial art style there are private lessons available. I'm bald, fat, and sixty years old and if I can take these classes you can too. Shifu Jeremiah is patient (and I have tested it) and will take the time it needs to give you the training and confidence you need to carry forward. If your on the fence, take a look around you and consider the world you live in. On my first day of class I learned how to parry a knife thrust and return the favor. Don't wait to be the next statistic, you are either a sheep, a wolf, or a sheepdog." -- Kevin S.
