So I'm back giving another update and review of Ethos. I'm still here and finally got my purple belt last year. I can't imagine training anywhere else. Both instructors Ron and Jerry are phenomenal instructors who foster an amazing training environment for all walks of life and for the different reasons people train whether it's for self defense, competition or just exercise. Ron and Jerry also have competent and capable instructors who help teach and train to r classes. These assistant instructors are top notch as competitors and teachers. I'll prolly train here until I'm an old man with a cane. Best BJJ school in Orange County. read more

I've trained at multiple schools in so cal and Ethos is by far the school with the best learning environment for adults and kids. All instructors are very professional and knowledgeable and classes always start on time. Doesn't matter if you're a completely brand new or more experienced Ethos should be your first stop read more

I can't say enough good things about this place. Not only has my daughter developed good self defense skills, she has developed friendships, confidence, and a love of BJJ. The instructors are tough but positive. The kids demonstrate good sportsmanship and support each other in practices and tournaments. I am so happy we found this positive and welcoming space! read more

great BJJ, and even greater people!! if you want to learn grappling definitely come to Ethos!

The absolute best in Jiu Jitsu training. The owners Ron and Jerry are one of the most sincere and best people you will get to meet in life. They are not only your instructor but partners in your journey. I remember when I first started I was intimidated but there is such a sense of family and helpfulness there that you will succeed no matter what. I feel extremely blessed and lucky to have found this place and look forward to future rolls with the family. read more

Great instructors and welcome atmosphere. Not intimidating for beginners and well suited for more advanced students.

In from out of town. Great place to train! Great instruction and crew. I highly recommend stopping by.

Started training here a month ago and couldn't be happier. Great instruction - all classes run by black belts (Ron and Jerry) - they know their stuff and are very involved/ hands-on and training/ helpful/ quick to share their knowledge. Everyone in the academy is super welcoming to both newcomers and "migrating" higher belts. :) Also, the academy is super clean (mats cleaned/ disinfected throughout the day) which is really nice (and you can't say for all academies..). Good kids program too (WISH my parents got me training at that age...). Highly recommend! read more

Phenomenal teaching and great mix of students and belts levels in each class makes the rolling fun and always some tuff rolls but even beyond this the culture of Ethos is really awesome the people are great, the black belts and upper belts really set the example. This is not an exaggerated statement if you just want to get a workout in and learn some Jiu-Jitsu or if you want to compete and get some high-level training Ethos really does have it all. You won't regret it! I have been training for 12 years in mixed martial arts and Love this gym! read more

Here we are two+ years( +\ - a few) later and just now writing this. Well worth the wait though Ok, Rewinding back to 2.5 years.........It started with me telling my husband that he needed to find hobby. That hobby turned into a lifestyle In less than a month. He was waking up at 6 am 5-6 days a week to "roll" right before work. I swear, he wasn't obsessed(winking face) My husband explained to me multiple times the benefits to this new lifestyle and decided to enroll 2 of 4 of our kids. Our two older kids weren't as stoked as their dad.They thought it was just another activity to keep them off electronics. Maybe it was (shhhhh) but with the patience of Ron,Jerry, and Wendy our children have grown with so much confidence in who they are today. No words or at least mine could explain how thankful we are to find this place. Can't wait to enroll the smaller 2 girls when they're older and maybe myself If I can give up the acrylic nails.all jokes aside. read more

Pre COVID, we moved locally and needed to find a new BJJ school for the kids. After leaving a highly respected school with excellent instruction, we found ourselves running into places that didn't compare to that level. That is until I found Ethos. Ron and the crew were very welcoming and the vibe during their classes was very professional and over all they truly cared and it showed during instruction. They asked me why I chose their school and I didn't know how to explain that it was a gut feeling in terms of their vibe as people. Anyway. Take your kids here and sign up . read more

Great BJJ training and teammates! Everyone is welcoming and friendly. Professors Jerry and Ron are outstanding teachers and are motivating and pay attention to everyone. It's a smaller/family oriented BJJ school, and that's perfect for me, give them a try and call 'em up, you won't be disappointed! read more

Great gym. Of course there are more men than girls, but there are enough of us to train if that makes you more comfortable. The mats are new and clean, very spacious so you don't bump into each other; the people are friendly and of all ages. Morning and evening classes, open mats on Friday and Saturday, gi and no gi. Children and youth classes if u want to make it a family thing. Great teachers who are also great people. And also international athletes offer seminars for members. Very welcoming environment. Free trial available. read more

Ethos Jiu-Jitsu Fullerton - Team support for competing members - Brazilian Jiu-jitsu Near Me - Fullerton, California

I've been interested into training Brasilian Jiu-jitsu for awhile now and Im so happy to have found such a welcoming and encouraging academy. Head professors Ron and Jerry are very thorough and detailed with their instructions with each technique. This emphasis to details greatly help new students like me to gain confidence in properly executing the moves in drills. Everything we drill then is practiced with open mat to finish the class which for me was the fun about this martial art, figuring out ways to apply our practice in the live sparring. Whether its your first time trying a combat sport or a high level practitioner, this place has it all! read more

great people all around. every one is respectful while sparring and focus on the technical aspects of jiu jitsu instead of using brute strength to win. perfect place for newcomers and seasoned practitioners alike read more

Great people there. Highly recommended to anyone looking into getting into a martial art or even if you just want to get into shape. Ethos is the place for you. read more

This is a great studio. The coaches are great. They really take the time to make sure the students are learning the different moves.

My 2 kids (11 & 13) started with Ethos on day 2 of their opening. They had never had previous training prior to this. Coming from an athletic crossfit background, my kids transitioned quickly and fell in love with this sport. The coaches Ron & Jerry (brown belts birthed out of Leon JiuJitsu) are very patient, and make each student feel welcomed and a part of the team. In just a few short months, they've had opportunities to roll with different belts and learn so many vital self defense skills. I began a month ago & truly appreciate the patience and the passion these coaches have for beginners. I look forward to rolling and growing in this new journey. They have self defense classes once a month on saturdays. By appointment, they also have a licensed massage therapist that helps stretch tight muscles, therapeutic massage, and relaxation. Whether you're new or experienced, come out and give it a try. See you on the mat! read more

What an awesome place. I was a little anxious about signing up but the instructors helped me feel welcomed. Overall great experience.

My son loves the kids class! Great opportunity for him to learn Jiu Jitsu and hang out with other kids. Awesome teachers who take time throughout the group class for each kid and make sure they're picking up the techniques! read more
