The Marin Dojo, Inc. team states that it strives to build athletes who can apply their training towards other activities, school, and life in general, and describes the academy as high-energy and fun, dedicated to self-improvement. The stated focus is not on brute force or competition, but on being the best version of oneself, with an emphasis on building character, respect, humility, and passion, and fostering a culture of respect and safety while training martial arts. The Marin Dojo, Inc. offers a multi-layered training system, and every course is rooted in real-world self-defense and personal safety, not point-based competition. The program offers a Free Trial Class, a Limited Time Offer: One Week Free Special, and a Limited Time Offer: One Week Free Trial, and also offers The Dojo Birthday Parties. The Dojo invites nearby communities including Ross, San Rafael, and beyond to join them, and its generosity to a local fundraiser is commended.
