Teaching and Dojo Philosophy
At The Martial Arts Academy, we teach the martial arts as an all-encompassing life skill. You will learn all aspects of the martial arts as a complete study, from tradition to health, fitness, realistic self defense, meditation, and competition. The idea emphasized is not just a 2-year quick study, but and in-depth immersion, where the idea is to develop over many years while maintaining your health, vibrancy and person growth.
Personalized Instruction
About Personalization: There are many reasons for learning martial arts, and each person that takes up training is different from one another. After an overview of the general training program of their chosen art, the student is then given a training routine based on their individual mindset, body type, personality and goals. With expert Instruction from each teacher that have over 10 years experience, this open approach combined with traditional martial etiquette and discipline, allows each person to thrive and express themselves in their chosen fighting art.
Authentic Lineage
About Authentic Lineage: An often overlooked factor, Lineage Systems are a very important element to consider when selecting which martial arts school you are looking to learn from. Much like looking for a reputable college like Harvard, for example! Many of the same aspects also apply when researching a martial arts school. At The Martial Arts Academy of Marin, our Karate lineage is authentic, making it a complete method, cultivated over centuries of the time tested Master to Disciple instruction. Not only will you be getting expert instruction, you will join the instructors side-by-side in their lineage as well.

The testimonials
My 13 year old had been doing gymnastics for years, but was looking for something different. They joined the teen/adult classes, and have absolutely loved it. The environment of the dojo is really positive, and you can sense the foundation of respect, integrity, and discipline in everything they do. The teachers are inspiring and have been really welcoming and encouraging. I'm super grateful we found this place, in just a few months it's become a new passion!

I love how kind, patient, devoted, and genuine Sensei Will and his advanced students are; 2) the historical & philosophical contexts and spiritual power of the karate practice.
Marie Thouin
Student
There isn’t a big emphasis on getting belts and competing, the class is about actually learning karate, its principals and way of life. I am so grateful we decided to come here.
