Meet Our Instructors

Manny Grijalva

Manny is a certified Krav Maga instructor under Krav Maga Worldwide and serves as the lead instructor at G3 Combatives Training Center. With over three decades in the self-defense world, Manny brings unmatched experience to the mat. He holds a black belt in Kenpo and instructor certifications in eight additional systems—but what truly sets him apart is his unwavering commitment to people. For Manny, this has never been about collecting ranks. It’s about saving lives. He founded G3 Combatives after recognizing a critical gap: too many people were caught between unrealistic traditional martial arts and combat sports that didn’t focus on real-world violence. G3 was created to be something different—a place where everyday people could learn practical, effective self-defense in an environment rooted in respect, trust, and purpose. Manny is passionate about helping people become stronger, more confident, and truly prepared. Every class he teaches is built on a simple belief: that everyone deserves to feel safe, capable, and empowered.

“When someone walks through our doors, they’re putting their safety in our hands. I take that seriously.

My responsibility is to make sure they leave stronger than they came in—mentally, physically, and emotionally.”

Kat Montaño

Kat is a certified instructor under Krav Maga Worldwide and holds rank in stick combatives.

She didn’t walk into her first Krav class looking to become an instructor—she walked in looking for something real. Something that would push her, challenge her, and make her stronger. What she found was more than self-defense. It was transformation.

Krav Maga didn’t just teach her how to fight—it reshaped how she moves through the world. It taught her to own her space, trust her instincts, and never back down. That kind of power doesn’t stay on the mats. It follows you everywhere.

Now, as a lead instructor at G3 Combatives, Kat brings that same energy into every class. She doesn’t train people to look tough—she trains them to be tough. To be ready. To be unshakable.

This isn’t about perfection. It’s about showing up, doing the work, and walking out stronger than you walked in.
