M3 Karate in Gilbert, AZ, is a premier martial arts school led by Master Mendoza, offering expert karate training for all ages. We focus on developing not only self-defense skills but also confidence, discipline, respect, and life lessons through structured classes. With a high instructor-to-student ratio, personalized feedback, and real-life scenarios like bully defense, we create a supportive environment where students thrive. Our programs include incentives for at-home responsibilities, flexible scheduling, and a community-driven approach to foster growth both on and off the mat.
We've previously tried other karate schools with our first kids (at big chain schools) and always felt it was just a conveyor belt system to push you through belts and milk you for $$ along the way while the kids just memorized basic routines. For our 3rd child, we came across M3 Karate as it was near our house, and the reviews were all VERY positive, so we gave it a try. Within 5 minutes of our intro class, we knew this was the school for our child. Our son had issues with confidence and coordination, and from the start, he held our son accountable and brought out a voice in him we hadn't heard before. After 2-3 months at the school now, our son enjoys the classes SO much and shows so much respect towards his teachers, and we feel confident we will remain at this school for a long time. The owner (and main instructor), Master Mendoza, holds the kids and parents accountable, provides them with real-life scenarios (bullies, etc) and he always has at least 3 instructors (all former students) for each class so your child gets a great experience with a good student-to-teacher ratio at this school. His instruction extends beyond the karate studio as he encourages his students to be better people at home. Our child now cleans his room more often, makes his bed and has a stronger voice in public with new people...alot of which comes from Master Mendoza offering incentives and also having certain "stripes" on their belt that come from at-home and/or school items. They offer flexible class schedules that work with our schedule and Ms Amy (owner) keeps everything organized on the back end for a nice experience on all fronts. We can't recommend M3 Karate enough and encourage others to give it a try.
My daughter has been training with Master Mendoza and his instructors since November of 2023. His deep knowledge of martial arts is matched only by his passion for teaching. Master Mendoza's classes are well-structured, challenging, and incredibly rewarding. He pays close attention to each student, offering personalized feedback to help everyone improve. His patience and encouragement create a positive and supportive learning environment. Under Master Mendoza's guidance, our daughter has not only improved her karate skills but has also gained confidence and discipline. We highly recommend him and his instructors at M3 to anyone looking to learn martial arts from a true master!
Master Mendoza is a wonderful instructor! Beyond just the martial art skill, he teaches character. I didn't realize the extent that my children would be learning eye contact, communication, boldness, how to lose and win with grace, giving back to the community, how to be an entrepreneur, discipline, respect and so much more. This martial arts home has made a huge difference in my kid's behavior. Master Mendoza has an amazing range of martial arts skills that he requires of the kids and he even runs through bully scenarios that are practical. I highly recommend!!! Absolutely amazing!
We have been going to this studio for 2.5 years and my child loves learning karate and all the junior instructors. Master Mendoza makes it fun too! I had no idea before that it is not just about leaning a type of the Martial Arts, but also about getting more confident, focused, and disciplined. Our child is learning to be more responsible and work hard for the stripes and belts. She also is learning that one needs to wait for the good things (like earning enough Ninja coins to spend on something big). We are super happy for her also to learn how to defend herself, but as you see, it is not the first thing I pointed out here.
Master Mendoza and team are awesome! We started our 4 yo here a few months ago and he loves going to class. Classes are small and there are several instructors on mat helping the students. Parents also participate in drills which is nice for learning some drills to do at home with your child. We’re so happy we found M3!
