    Attended the core survival class with my seven year old and it was a great experience. My daughter…read moreloves being outdoors and has become obsessed with "survival" shows/videos. She asked if there was classes for survival. Luckily I found California Survival School. We were fortunate to have Dan as the instructor. He background is quite extensive and impressive. He was very knowledgeable and helpful. Although I thought my seven year old would get bored with the lecture portion, Dan kept the group engaged throughout. The hand on activities were our favorite, like building a tend properly. Both my daughter and I enjoyed the class and learned essential skills that can be used in everyday situations. Highly recommend the class for any age.

On the final day...I felt like I knew many of the other clients, and staff, there for much longer than the fees days we had shared together. I recommend these classes to anybody interested in learning techniques that could save your life in a multitude of situations in a positive environment with instructors that genuinely Love what they are doing. Had some amazing conversations with new friends by the fire pit at night as well. Adult class + camp. Adam (head instructor), Josh and Aiden (the staff I had for my courses) were fantastic with different but complimentary personalities and a wealth of knowledge that naturally engaged everybody. Only criticism is that the website says you can fish...but you won't have time.

    We have had a wonderful experience at Magikid Robotics Lab in Diamond Bar! My son has been taking…read morerobotics and coding classes here, and he absolutely loves it. The classes are engaging, creative, and a great way for kids to learn STEM skills while having fun. The instructors are patient, knowledgeable, and do a great job encouraging kids to think creatively, solve problems, and build confidence. We have seen my son become more interested in technology and excited about learning. We highly recommend Magikid Robotics Lab in Diamond Bar to any parents looking for a fun and educational program for their children!

    I found this place and was surprised I hadn't heard of it since he's been going to school in DB for…read more5 yrs. Decided to send my 9 yr old son to a trial coding and robotics class. Usually the first class is free but I did pay $30 - $40 for each trial class. My son didn't like the robotics class at all. He said the instructor was having a hard time keeping the kids engaged or on task. He also said the classroom was dirty and there were not enough parts or components so they had to get some from other rooms. As a new trial student you would think the instructor would give some background or guidance but he said there was no explanation or instruction from the instructor on what was going on. She was just helping kids that needed help or find parts for them. He knew one of the other kids in the class so he just sat next to him and observed (not sure why I had to pay for him to just sit & observe). He was supposed to take the coding class right after, but he was already done and didn't want to go back inside. We went after school on a Friday so he was already tired. Since I already paid for both trials, I rescheduled the coding class. They were very accommodating & rescheduled us a couple of times. He said this coding class was much better and the instructor was better. All the coding was done on the computer. My impression from the 3 times I walked in was it's chaotic: kids darting here and there and some parents picking up their kids. There are tables with robotics and coding plaques or instruments by the entrance and hallways, cluttered & dusty. The 2 young gals there were very nice but just sitting at their desks looking at their computer monitors amidst the chaos. They didn't ask him how the trial class went. Didn't seem organized or clean. I had high hopes with all the 5 star reviews on yelp but was not impressed. It's in a narrow and long strip mall with different businesses: a dentist and 2 - 3 other tutoring type afterschool places. Looks like a lot of local kids hang out after school. My son has gone to a dozen or so lego, coding and robotics camps over the last 2 summers and he said he prefers those classes/camps.

The dedicated staff provides intentional, personalized instruction in small class settings, ensuring each student's individual needs are met. The engaging, challenging curriculum encourages students to think critically, explore new ideas, and develop a love of learning. The OLS Summer Program is also well organized, with academics in the morning and fun enrichment activities in the afternoon. Parents have the convenience of purchasing a school-provided lunch for a small fee, with options such as Panda Express, Subway, McDonald's, and Chipotle. OLS is a great choice for families looking for a supportive, engaging, and enriching learning environment year-round.

    We are a returning family and had a great experience last summer, which is why this was so…read moredisappointing. This summer, we learned that our daughter was disciplined by being made to stand against the wall as a "time out" for running around the center. This was never disclosed to us as part of the school's discipline policy, and we were not informed at the time it happened, we only found out because our daughter mentioned it. Even more concerning, our daughter told us another child was made to stand against the wall as well, and was reportedly told "who told you you could sit down" when he tried to sit. We don't know every detail of that second incident, but if true, it points to a culture of discipline that relies on humiliation and intimidation rather than positive guidance. We've reported this formally and are waiting on a response. A call was promised today (7/2/26) however, I have not received a call yet. Until we see real accountability and a change in disciplinary practices, we can't recommend this school anymore.

    This review has been long overdue, and I'm so glad I finally had the chance to write it…read more About a year ago, I decided I wanted my boys to start jiu-jitsu. As a mom, I believe it's so important for children to learn basic self-defense not because I expect something bad to happen, but because I want them to have the confidence and skills to protect themselves if they ever need to. At first, my boys were nervous and intimidated. We visited a few schools before making a decision, but from the moment we walked into Teragi, we knew this place was different. Everyone made us feel like family. The professors and coaches are exceptional not only because of their experience and skill, but because they genuinely care about every child. They encourage, support, and meet each child where they are. I especially want to mention my youngest. Jiu-jitsu didn't come naturally to him at first, and he struggled to understand the techniques. The professors and coaches were incredibly patient and never made him feel like he was behind. They allowed him to learn at his own pace, and now it's amazing to see how much his confidence and skills have grown. That patience meant so much to our family. There's no pressure for kids to be the best. Every child learns differently, and the professors and coaches truly understand that. Since we homeschool, Teragi has become more than just a place to train. My boys have made wonderful friendships, and we've found an incredible community. I also have to mention how clean the academy is! It never has that old gym smell and is always welcoming. I've watched both of my boys grow not only physically, but mentally and emotionally. They're more confident, disciplined, and respectful. If you're on the fence about jiu-jitsu because you don't like the idea of your child being on the ground, I completely understand. I felt the same way. But the reality is that many real-life self-defense situations end up on the ground, and knowing what to do can make all the difference. Thank you, Teragi, for creating such an incredible environment for our children. We are so grateful to be part of the Teragi family, and I couldn't recommend this academy more.

The owners, professors, and coaches have cultivated a superb gym culture. This gym is safe, friendly, and supportive. The facility is modern and clean, and they've invested in a foam block subfloor beneath the mats for softer landings. As far as I know, this is the only gym in the area that offers women-only classes four times per week and a bi-monthly community open mat for gentlemen 40 years and older. My kids train here after school 4-5 days a week, and they love it. The kids' professors and coaches are experienced and amazing teachers. I'm especially thankful for the young coaches who were so patient and kind to my boys when they were hesitant and shy after first starting. And my pocketbook is especially thankful for the discounted rates for additional family members. If you're looking for a place where the whole family can train, grow, and feel welcome, I can't recommend Teragi highly enough.

The staff and sensei's provide such a fun, loving, welcoming, and happy environment to the kids. My daughter has enjoyed everyday that she went so much! Drop offs are a breeze but the pick ups are tough because she never wants to leave. You can tell that everyone who works here truly love what they do and cares about every person who walks through their doors. I had to pick up my daughter in the afternoon to take her to an appointment and the staff was so flexible with my request! They let me pick her up at the field trip and they let me drop her back off at the center. She missed getting ice cream because of the appointment but the instructor saved one for her when she got back this place is magical and wonderful!

I 100% recommend this AMAZING opportunity and highly encourage you to give it a try. Thanks AMAA for the A++ service and programs provided for our children!!
