★★★★★ "He has a bigger sense of achievement. There's a lot more focus, even with homework and other things." - Madison, Parent of Student
⭐️⭐️⭐️⭐️⭐️ | Diana Mikhno, Parent of Two Students
The kiddos love coming to class! They would come everyday if they could! When they do a drill they look at me with the biggest smile. I love seeing them try their best, they don't give up! Josh and Lauren, you are doing great things for our kids, the next generation!
⭐️⭐️⭐️⭐️⭐️ | Kristina Irlich, Parent of Two Students
Absolutely would recommend Hybrid! My son has shown so much improvement, not only on the mat but also in his self confidence! Both Lauren and Josh have shown so much kindness in our short time here! We are super pumped to keep growing with them! Thank you for all you both do!
You've tried other activities. Nothing's clicked yet.
Most programs keep kids busy. Few actually build them. Most gyms offer a workout. Few offer a community worth showing up for.
Your child deserves more than just an activity
- They lack confidence or shut down in new situations
- Focus and listening are a constant struggle at home and school
- Screen time has replaced every activity you've tried
- Classes elsewhere felt like chaos, not coaching
You almost didn't come in. We understand.
- You've walked into gyms that felt cliquey and unwelcoming
- Work stress piles up and workouts feel pointless
- You want a real community, not just a membership
- Traditional gyms stopped keeping you accountable
★★★★★
“I would highly recommend this school for every kid and adult. Just the way you guys genuinely care, you can tell. You're genuinely caring about all the kids and their success and making them better.”
- Destinee, Parent of Student

“He is proud of himself with little accomplishments at home… He has a bigger sense of achievement. And then at home, respect has definitely increased a lot. There's a lot more focus, even with homework and other things.”

What Makes Us Different
Classes stay under 20 students
Your child won't get lost in the shuffle. Neither will you. We keep class sizes small because individual attention is how real progress happens.
Josh learns your name by the end of the first class
When Kirstyn walked in for the first time, Josh introduced her to every single person in the room before the warmup started. That's how every new student is treated.
Results you see at home first
Parents tell us they notice changes off the mat just as soon as they see them on the mat. That's the point. Confidence that travels.
No cliques. No egos. No fight gym energy.
A 53-year-old student said he wishes he'd started 30 years ago. A first-timer sat in her car for 20 minutes before walking in. She signed up on day two.
You're actually learning martial arts
Not just staying busy. Not just getting a workout. Every class has a purpose and every session ends with something learned and something to build on next time.
Family pricing so everyone can train
Military, first responder, and family discounts available. The best version of this community is one where families train together.
Structure is How Confidence Gets Built
Most programs choose between too loose and too intense. We built something that meets in the middle — firm enough to create real growth, warm enough that students want to come back.
For Kids
Every class follows a clear structure. Students know what to expect, coaches hold real standards, and every class ends with something learned. That consistency is what actually builds confidence that parents notice.

Built for beginners No experience needed. Every new student is guided step by step from day one.
For Adults
You'll sweat, you'll smile, you'll be challenged, and you'll actually learn something every class. But the environment is the part you need to experience yourself. No cliques. No ego. Adults who show up, work hard, and support each other.
-

Everyone starts in Foundations No experience required. Training moves at a pace that works for you.

Try It First. Decide After.
Within two weeks, your child will stand taller, make more eye contact, and show more focus at home and school. If you are training you will feel the difference in yourself as well. If you don't see it, your trial costs nothing.
Every new student starts with a free two-week trial. No pressure, no long-term commitment, no decision required on day one.
Such a fantastic place! Josh and Lauren make you feel like you've been part of the family from the minute you first walk in.
The training is fantastic! Everything is calculated to where you learn first and then apply second so you never feel like you are behind.
I'd give this 10 stars if I could!
⭐️⭐️⭐️⭐️⭐️ | Evan Fjellin, Adult Student
I love it here for my children. They are very up to date in this lane. My children have learned so much in only a few months. He makes it easy and fun. I would recommend HMA all walks of life. Everyone can find joy in the encouragement, team building and trust that you are in great hands. Thanks Josh and Lauren a major part of my family. 🥋🫶🏽

"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."
⭐️⭐️⭐️⭐️⭐️ | Andrew Jamison, Adult Student
Josh & Lauren
Real Owners. Real Coaches. Real Results.
Hybrid Martial Arts is owned and coached by Josh and Lauren Sivel. It is not a chain. There is no head office. The people teaching your child are the same people who built this program from the ground up.
Josh has over 10 years of coaching experience. Lauren has been helping on the mats for the same amount of time. They have seen what big, crowded schools did to kids who needed individual attention. And they have felt the stress of not getting a call back or being able to talk with someone who can actually help. Every student gets introduced by name. Every parent gets a response.
Valerie put it best: "I do not feel like you treat the students as just income." That's not a goal. That's just how Josh and Lauren run things.
Three Steps. That's It.
Show Up
No gear, no experience, no preparation needed. Just arrive. Josh or Lauren will introduce you to every person in the room before the class starts.
We Handle the Rest
Beginners are guided step by step from day one. You'll never be thrown into something you're not ready for. Training moves at a pace that works for you.
See It At Home Too
Most parents notice changes happen on the mat first. But the real power is when they start seeing at home. We guarantee visible results within two weeks.
Not Ready Yet? Start Here.

Frequently Asked Questions
Before You Walk In You May Have Questions

Quite the opposite! The goal of martial arts is to teach students how to show restraint and avoid violence, while controlling their emotions. We never want your child to have to use their training to defend themselves, but we absolutely want them to have the skills in case they need to.
-
Josh and Lauren will introduce you to every person in the room before class starts. You won't be thrown into anything you're not ready for. Most people who were anxious before their first class sign up within the first two visits. Your goal on your first class is to have fun, feel comfortable, and learn something new.
-

Absolutely! We encourage parents to watch their children in their Kids Martial Arts lessons. We love parents who are involved and want to watch class. And so do their kids! Even better, join into some of our martial arts classes for adults. Nothing is cooler than families who train together!
But if you also need a few minutes of “me-time”? Simply drop them off if you need it. They will greet you with a huge smile when you return, because they had SO much fun!
