Life-Changing Outcomes

Our instructors are more than just coaches

Our instructors have all experienced the life-changing, confidence-building benefits of martial arts firsthand. In fact, most of our instructors started with AMAA as children! Because of this, we all deeply understand how a positive environment can bolster your child’s healthy development...in all areas of their life.

In everything we do, we embrace kindness, community, and compassion. Our knowledge, passion, and training provide the backdrop where your children can learn the skills that will help them thrive in all aspects of life.

OUR STORY Began WITH A LEAP OF FAITH...

In 1992, founder Shihan Brad Wenneberg, a retired police officer, and his wife, Bonnie left the comfort of their successful careers to follow their dream. That dream was to open a martial arts studio.  

Their family had already experienced the benefits of learning the values and principles of martial arts. They believed the wider community could benefit, too. And they were right.  

The American Martial Arts Academy was not just well-received, but celebrated as one of the best martial arts studios in the country. Over the years, to meet the growing demand in our community, we opened a second studio in Placentia in 2012.

Our flagship dojo in Fullerton is led by Shihan and Bonnie’s son, Sensei Jason.  And our Placentia dojo is led by Senseis Nikhil & Megan Joshi, who trained with Shihan as children.

We believe it’s this family centered focus that really makes the
American Martial Arts Academy Difference.

With us, your child gets more than just martial arts training. They get an entire team of caring, experienced instructors who are dedicated to seeing them shine.

“WE LOVE THIS STUDIO!! Our son is 2.5 years old and has been coming here for a few months now & WOW! We’re so pleased with everything our son is learning here! He’s so young but the discipline and positive attitude he is picking up here is definitely noticed in our everyday lives.

Everyone is so friendly, he absolutely adores the staff! The studio offers flexible class schedules so it works out great for us. Plus it’s so nice and clean inside! We definitely recommend this studio to anyone who’s looking to get their kids involved in martial arts.”

As a parent, I have been thrilled to see amazing maturational changes in my kids. They don't realize how hard they are working because they are having fun. This is because Sensei, Mrs. Joshi and Mr. Sims are skilled at developing relationships with the kids, and keeping classes fun, upbeat and energetic. As a child psychologist I appreciate their inclusiveness and respectful attitude to different learning styles. I get to observe a lot of teachers in my work and feel strongly that these are some of the best. Lastly, as a busy mom, I have to say that I really appreciate the flexibility in attending classes. Overall a fabulous place!

We looked and researched an activity center for our 6-year-old daughter. She was a little shy at first and took a few days to warm up, but boy she loved it! On the first day, she came home in the afternoon and said she wants to continue with the karate academy. We are very happy with their professional approach and very friendly style. When you walk in they greet you with your name. WAY TO GO!

“American Martial Arts Academy has become our home away from home. Excellent, caring staff who will be dedicated to your children like they are their own. We started last year during the summer and found that their balance of indoor fun activities, local field trips, and weekly park days gives children both variety and structure at the same time. The karate instruction has enabled my children to develop both physically and mentally. Highly recommend AMAA for summer school, aftercare, and karate classes. You will find a clean, well-kept establishment, and a great community of families, too!”
