Our Story

Why We Started Hybrid

We both met while training on the Martial Arts mats. We both love training and helping give back to others. Both of us have trained since we were teenagers, attended seminars, and basically lived at the dojo. After attending a seminar in California, Josh was inspired to start his own school and create his own impact within the community. With the push from Lauren they started Hybrid Martial Arts together in April 2025.

When we decided to open Hybrid Martial Arts, we had many goals and a vision for the school. We wanted somewhere that was focused on Martial Arts at it's core, but a place that wasn't aggressive or intimidating. Somewhere you could go to relieve some stress, train with friends, and feel welcomed and cared for. We trained at multiple schools before, but could never find the feeling we were looking for, so we created it here.

The name Hybrid came from Josh and Lauren's roots of an MMA style program. And we also believed that the best Martial Artists embrace the best of several styles. That is why you will see a range of styles blended together on our mats and why our students feel confident and capable standing, on the ground, or in any other unpredictable situation a fight might lead to.

What We Believe

Our goal has been to build this school together with our students since day one

"A true Martial Artist is someone who takes what they have learned on the mat and applies that to another area of their life off the mat. My #1 goal is to teach students lessons that will apply to their lives off the mat and help them become better people as result of their training."

Our Coaching Philosophy

How We Show Up for Students

We opened our doors because we wanted to serve our community better. Every day we show up for our students who are showing up for themselves.

01

Structure Builds Discipline

Every class has a plan. Every 8-week cycle has a curriculum. Students always know what they're working on and why. That is how we keep classes fun and positive, but also productive and meaningful.

02

Meet Students Where They Are

Time and time again we have seen programs and schools that lack the proper coaching to make them great schools. The first step is meeting students where they are and building from there.

03

Every Class Moves You Forward

We believe every class should improve your life by at least 1%, and we genuinely mean that. Small, consistent progress is what builds real mastery over time. That's the standard we hold every class to.

Josh makes it real for the class members… he has us actually get into situations with teammates so that we know how to handle ourselves both physically and mentally for when it's real.

⭐️⭐️⭐️⭐️⭐️ | Kurt Smith, Adult Student

Week after week, we learn different techniques from various forms of martial arts all while sticking with the basic fundamentals. Transitioning to Hybrid Martial Arts has been, without a doubt, one of the best decisions we’ve made.

⭐️⭐️⭐️⭐️⭐️ | Amy Cook, Family of Four that trains at Hybrid

"I'm a 53-year-old male. Life gets in the way and before you know it, 30 years has passed. Hybrid Martial Arts has given me the opportunity to get active again at my own pace. Wish I had started 30 years ago."
