Blackbelt collective offers 2 trials days for kiddos which was perfect to test it out. Immediately my daughter was hooked, she wanted to go every day! The monthly payment option gives you access to unlimited classes each month! My daughter has learned the core values, how to respect others, and how to protect herself. The instructors are clear, consistent, and passionate. They really care about the kids and want them to learn how to protect themselves if they are ever in danger. Communication with Mrs. Jodee, the kid's program director and the owner, Abel, has been so easy and they've answered every question that I've had along the way! Blackbelt collective Krav Maga has been a perfect fit for our family and I keep telling my friends and family about it! The goal is for my husband and myself to start adult classes soon, so we can all train as a family!

We've been part of Blackbelt Collective Krav Maga since 2022, and I can honestly say it has changed our lives. This school is different. Their motto is simple and powerful: "Get home safe." That's why I enrolled my kids. At the time, my middle-school son was being severely bullied. He was smaller, quieter, and struggling. After enrolling in Krav Maga, the bullying stopped completely. Not months later -- immediately. What he gained wasn't aggression... it was confidence, awareness, strength, and self-respect. He became physically stronger, mentally tougher, and more sure of himself. He has never been bullied since. Now all of my children are enrolled -- including my toddler -- and this gym has truly become family to us. Why Blackbelt Collective is different: * Strong youth program (ages 3+ through teens) * Excellent adult program (beginner to advanced) * Classes for all fitness levels -- no experience needed * Unlimited classes -- come as often as you want * Morning, midday & evening adult classes (great for working parents) * You can sit, watch, and observe your child at any time * No pressure, no ego -- just support and growth * Instructors who have been there from day one and genuinely care It's also an amazing stress reliever. If you love working out -- or even if you just need a healthy outlet -- Krav Maga is an incredible way to release stress, built-up tension, and aggression in a controlled, empowering environment. It's not just about self-defense; it's a powerful way to take care of your mental and physical health, improve stamina, strength, and overall well-being. The instructors aren't just teachers -- they become people your kids trust. As a parent, that matters more than anything. What gives me the most comfort is knowing that as my kids grow -- whether they're hanging out with friends, going downtown, or living adult life -- they will always carry their "secret weapon": the ability to protect themselves and make it home safe. New Year Special (January only!) Blackbelt Collective is currently running a great New Year deal, making it one of the most affordable and flexible programs around. Monthly Membership Options: * Month-to-month: $219/month * 6-month: $199/month * 12-month: $189/month * Enrollment fee: $100 (includes uniform shirt) Additional discounts: * $25/month off for additional family members * First responder discount: $179/month * Homeschool program: $209/month * All programs = unlimited classes First TWO classes are FREE -- just sign a waiver and try it out. This is not like some martial arts programs where you're limited to two classes a week. You truly get your money's worth here. The school is led by Senior Instructor & Owner Abel Martinez, and the entire team is patient, skilled, and incredibly supportive. If you've been on the fence, thinking about confidence, safety, fitness, stress relief, or overall health for yourself or your kids -- this is the sign. 17010 Magnolia St, Suite B/C, Fountain Valley Call or text: 714-536-7007 blackbeltcollective.com I recommend this place with my whole heart. You will see the confidence, stamina, growth -- and yes, you might shed some happy tears along the way.

We decided to drive 12 hours to attend a class with them. My son is 15 years old and he has been training karate over 6 years and he is an elite competitor. My daughter is 12 and has been training over 4 years. We were not let down! The training was bar none exceptional. The attention to details in competitive karate is really amazing. The conditioning and drills taught carry over seamlessly to excellent results. Their program methods facilitates students to achieve precise technique through observation, preparation, execution, recovery and completion. They have program for all levels from beginners to Advance and Elite. Their are many Karate Schools but few teach this high level of instruction. If you are thinking in enrolling your child in Karate school look no further JMAC is phenomenal.

I am completely disappointed with Master Hwang and his unethical practice in running his business…read more I regret not reading the Yelp reviews prior to committing to this program. After 2 weeks, Master Hwang asked me and my husband to meet to discuss my son's progress. He did not give us a heads up on what to expect. He pressured us into signing up for a year of martial arts when I asked to pay month to month as I am unsure how my son's schedule will look like and I emphasized that I need alot of flexibility because of that. He ensured me that we can sign up for now and we can modify as needed and he will be flexible. Once we signed up, I asked him for changes and reduction in the amount of classes per week, but rather than refunding me for that reduction, he refused and extended the amount of months my son will have to attend. My son did not enjoy the martial arts class after 2 months and I asked Master Hwang for any refund or credit that can be given. He flat out refused any refund but states he will reach out to me about credit to be used for later...it has been nearly a month and he still has not reached out to me although I have emailed, texted and called. If you would like your child to attend this program, please do not sign up for a year contract. I find Master Hwang's business practice extremely unethical. It completely ruined my trust and experience in his program
