They were previously called Sector Jiu Jitsu, but made a name change. Everyone at this place is super friendly and very helpful. My daughter came from a different academy and switched here a few months ago, and I can definitely see the improvement in her abilities! And for the parents with kids in charter school, they do take charter funds! Definitely check them out! read more

My kids just started at Sektor Jiu Jitsu in Corona and we're loving it so far. The atmosphere is super positive. Alba at the front desk is so friendly, helpful, and knowledgeable. She's made everything easy and made us feel right at home. I love that there's another Mom there to help the kids. The coaches are great with all the students--very patient, encouraging, and they clearly know what they're doing. The kids are super dedicated, focused, well trained and respectful, which is awesome to see. Highly recommend Sektor if you're looking for a great place to get your kids into jiu jitsu. Here they will truly learn the sport and gain the skillset and knowledge needed to become excellent athletes. read more

We've been debating on which self defense class we wanted our kids to join and we're SO glad we went with BJJ at Sektor. Our boys started in September and on their first day/trial class, the boys were really intimidated but Alba made them feel comfortable, explained everything and kept reassuring them. As soon as the boys saw other kids playing on the mat, they joined them and now, they ask to go everyday. The coaches are just amazing. You can tell they just want to teach and guide their students. Love that they try to make it fun while teaching and we can definitely see how much our boys have learned even in the past 6 months. Lastly, really appreciate the cleanliness of the facility and the refillable water station! :) If you're hesitant, just try a trial class and you'll definitely want to sign up right after! read more

If you're looking for a martial arts class (BJJ) for your son or daughter look no further! My son started when he was 4.5yrs old and he has been going to Sektor for 2yrs now! We love it here!

They have changing rooms available as well. Also, when you come to Sektor ask for Alba at the front desk, she is very helpful and will help you get signed in and get you started. See you there! read more

Thank You, Sektor Jujitsu! I can't put into words how deeply grateful I am for the incredible impact Sektor Jujitsu has had on my kids. Watching their transformation over the past few months has been nothing short of amazing -- not just in terms of technique or physical strength, but in confidence, discipline, and joy. From the moment we walked in, we were greeted like family. The environment at Sektor is warm, welcoming, and filled with positive energy. It's the kind of place where your kids are not just taught -- they're seen, valued, and uplifted. That means the world to a parent. The coaching staff is simply phenomenal. Patient, highly skilled, and deeply invested in each child's growth, they have an extraordinary gift for connecting with kids. My children look forward to every class, and I love hearing them talk about what they learned -- not just in terms of jujitsu moves, but in life lessons: perseverance, respect, resilience, and kindness. Sektor Jujitsu isn't just a dojo -- it's a second home. And the growth we've seen in our kids is proof of the care and excellence this place offers. Thank you, from the bottom of our hearts. read more

I'm a first degree black belt and was in need of somewhere to train for a week while visiting family here. If you are in Corona, this gym is the place. Excellent facility, Very friendly and welcoming atmosphere, and most importantly high quality jiu jitsu. I really enjoyed my time here and will definitely come back when I'm in town again. Thank you to Albert, Spencer, and Andrew. read more

Sektor has many people from all walks of life who are open and friendly. There are young and senior students at the gym. Both students and staff provide newcomers with warm welcomes into the community, and are eager to help you learn about jiu jitsu. I've grown to really appreciate the people at Sektor for their support on and off the mats. I started at Sektor as an adult student and I continue to learn every class. Life happens and sometimes I've needed to take breaks, but every time I've come back to continue the practice, the professors and other students have cheered me on. read more

Was in the Corona area for a few days. Spencer and the team were very welcoming and treated me like family. Got in some good mat time with some very skilled athletes! Definitely recommend checking out Sektor JJ in Corona, Ca. read more

Uncharted Jiu Jitsu - Martial Arts Near Me - Corona, California

I started with Sektor in 2020 when I decided that I was tired of watching TV and being a bump on a log. I went to Sektor's website and looked at their scheduled classes. After finding a class time what would work for me, I dropped in for the introductory class and was immediately hooked. Spencer welcomed me and approached his teaching in a way that felt like it was tailored to my particular skill level. From that day I was hooked and I havent looked back. From our day to day classes, gi and no-gi, to our special guest instructors from the world of BJJ, every opportunity to work with your friends on the mats is an experience that needs to be had to fully understand. If you were interested in just testing the waters or whether you were an experienced martial artist, Sektor is where you need to be. read more

I can honestly say Sektor feels like family! read more

Our kids have been going to Sektor Corona for approx. 4+ years. We started with Albert and Spencer, and we loved the way they taught classes to the kids. They kept them engaged while teaching. They had the perfect approach to teach the moves, the discipline, and still make it fun for them. Over the years, the kids began to learn from Andrew as well. The kids have grown so much in their skill under him as well. Sektor has created a wonderful family environment.It's been nice to have consistent instruction from Albert, Spencer,and Andrew. They have seen our kids grow up over the years and continue to give them feedback to improve. We recommend Sektor to other families as much as we can. Lastly, the confidence your kids will get from learning jijitsu is priceless. Definitely try them out. read more

Love this place for my kids! So happy they also accept charter funds! The mixture of instruction, listening skills, and life lessons is great during my kids upbringing! My kids are 7, 8, and 9 and the love spencer. We had to take a break for a bit but the kids never forgot him and kept asking to come back. Glad to be back! I love how the lobby is more spacious than others. I have 2 young kids as well so it's enough space to have them with me while my older 3 are in class :-) read more

If you're looking for a gym to take your son/daughter for great coaching and training when it comes to jiu jitsu self defense, this is the place to be. Class A coaches and are really great with kids! Spencer and Albert who are just awesome coaches. They promote kids based on their improvement and not like Taekwondo where you pay for the promotion. They challenged my son based on his skill level until he got really good with the techniques. Started taking my son in gym since May 2019. Had a rough first few weeks. My son cried during sparring. He was not used to being someone in his space let alone being choked and submitted all at once. We stuck through it until he didn't want to come back and went on hiatus for 2 months. However kudos to Albert and Spencer who continued to follow up and check in on us to encourage us to come back and affirmed us that it's normal for kids to have their first experience and feeling helpless. We decided to take him back and with Spencer's coaching and help, my son learned the ropes and is now thriving. We've been coming here since August and my son just loves to train at this gym and the comradery that he has developed has been a community for him. Best move we've ever made. Thank you spencer and Albert! read more

I had a great experience while in town visiting. The school is spacious and beautiful. Professor Spencer has a great teaching style and everyone at the academy was friendly. I'd recommend anyone to train at Sektor BJJ Corona. Great school and phenomenal instruction. Thanks for the hospitality everyone. read more

Sektor Jiu jitsu Corona is truly a unique place. It's more than the top notch training, friendly environment, and notable lack of drama and "ego" that seems to happen in many gyms. Professor Spencer (and coach Andrew) really invest in your jiu jitsu progress, help you to find/ nurture your "game", and encourage you to reach the potential they see in you. Initially I joined for the knowledgeable instruction, many class options, good vibes and opportunity to partner with Sektor Jiu Jitsu Chino. Now after being a member for a bit, I can see that Sektor Jiu Jitsu is all that, but also a place for genuine growth, partnership in learning, real camaraderie with like minded people, and my BJJ journey. These are really good people, learning pretty amazing jiu jitsu, having loads of fun, enriching each other's lives. Thank you Spencer, Andrew, Albert and teammates. read more

We were referred to Sektor from a neighbor of ours and we couldn't be more happy we decided to give it a try! We love the location and how spacious the inside is. Plenty of seating for parents to watch and a toy area to keep littles entertained. Our daughter is learning multiple new things every time she attends class and she enjoys being there. The higher ranked kids always include the newer kids which just creates a pleasant atmosphere. The coaches work well together and I genuinely feel they enjoy teaching their students and want to see them grow and develop a deep understanding of what Ji Jitsu is. We love it here! Also, they accept homeschool charter funds which is a plus for us. read more

I can't say enough good things about Sektor. All of the instructors are fantastic at passing on their knowledge. I enjoy training and rolling with all of the members of Sektor. I joined because of Albert, but I stay because of the Sektor community. read more

We definitely recommend Sektor to anyone considering jiu jitsu for their kids, both boys and girls! read more

I've been coming here for a little over a year and I have nothing but great things to say about this gym. From day one I felt welcomed with open arms.

The new location is huge with all the mat space you could ever want. read more

Bathroom is clean and changing rooms are available to use. It's in the same spot as Starbucks on Main Street. read more
