David Todd

Founder · Lead Instructor

A life-long martial artist, educator and learner, David started in the traditional arts at age 8 and quickly connected to both the physical and cerebral sides of training. Owner of Sentry Jiu-Jitsu, a 2nd-degree BJJ black belt and 5th-degree in American Kenpo, he draws on what is practical and useful in every art — a hard-hitting, detail-oriented, scenario-based instructor whose lessons are immediately useful off the mats. He's currently chasing his black belt in Judo.

Jacob Todd

Lead Instructor

On the mats since the age of 3, Jacob is a talented martial artist and a student of both Jiu-Jitsu and Judo strategy — and it shows in how he teaches. He gives students a complete gameplan, from takedowns and position control to submissions. Off the mats, he's a skilled stone mason who loves working with his hands.

Our Approach

No-Nonsense Self-Preservation

Our instructors value the time they share with students on the mat and pass on years of valuable insight, methods and tips that make learning more impactful. The grafting of styles — Brazilian Jiu-Jitsu, Judo and self-defense — comes together into a no-nonsense self-preservation system you can actually use.

You're guaranteed to learn something every class. Whether you're a complete beginner or an experienced grappler, you'll be met where you are and given room to grow.

★★★★★ 5.0 on Google

As a police officer, the self-defense techniques I've learned here WORK in the real world. Beginning my martial arts journey with this group has been one of the most rewarding things I've ever done.

★★★★★Matt BealerMember · Law Enforcement Verified Google

Joining the academy was one of the greatest choices I have ever made. I was welcomed in with open arms and given the opportunity to learn and grow while stepping out of my comfort zone.

★★★★★Elliott StrezMember Verified Google

I was worried being over 50 and starting Jiu-Jitsu. Everyone at Sentry is welcoming and the students work with you to grasp the concepts. Professor Dave breaks down everything from the novice to the experienced.
