Awesome and welcoming dojo! Last year I decided to give this place a try and Sensei Jonah is one of the best teachers I’ve had. Judo has shown me discipline and how you don’t necessarily have to be the biggest or strongest in order to defend yourself without even throwing a punch, not to say I’m in here for self defense but it is useful for that as well. The sport of judo is an amazing one and this is an amazing dojo.

Class is always fun, informative and gripping. Haha get it?! Anyways, Sensei Jonah and Sensei Cody are great teachers and they teach more than just the movement of Judo – I find that the lessons in class apply to many things in life.

I have a black belt in Aikido and decades of experience in martial arts and for me Sensei Jonah has been one of the best martial arts teachers l have ever had.

Fun, educational, and supportive environment to learn judo in. Sensei Jonah teaches all levels and often has many guests come in to share specialties in their techniques. Highly recommend 510 judo. He also teaches all ages.

As a long-time martial artist who’s trained with Jonah and Omar for many years, I have nothing but respect for their grappling. Both are incredibly talented and generous instructors as well as active fighters at the top of their game (Jonah is a recent national champ in Judo and Omar competes in the pro Brazilian Jiu-Jitsu circuit). They have a great adult group for both hobbyists and competitors and a thriving kid’s class also. Highly recommend 510 Judo for all grapplers in the area.

Friendly and supportive vibe. Good mix of ages, intense workout, excellent camaraderie. Friendly and supportive vibe, neither “aggro” (like some dojos), nor overly formal (like others). Jonah radiates a calm demeanor.

Great instruction and atmosphere. The training is solid but we also have fun.

Jim Lubinskas

Jonah is a fantastic coach. He is very positive and patient. There were no egos from anyone. Everyone was really friendly and helping each other out. Great place!

My child is supported here in the Tiny Judo classes. The instruction (led by Jonah Ewell) is leveled appropriately to be both fun and encourage skill building. The older children appear to also have this mix. I like that big kids help out the little ones, too.
