MEET OUR SENSEI

Sensei Roque de Guzman

Hello! I’m Sensei Roque de Guzman, a 3rd Degree Black Belt in Shorinji-Ryu Renshinkan with over 35 years of martial arts experience. My journey began at age 7 with Taekwondo, later earning a black belt in Shotokan under Joey Piamonte and Shorinji-Ryu Renshinkan under Shihan Manuel Gonzalez in San Francisco. For the past 25 years, I’ve focused on teaching Shorinji-Ryu Renshinkan.

My teaching philosophy blends traditional Karate techniques with modern personal development, emphasizing respect, focus, perseverance, and community. Whether you're a beginner or an experienced Karateka, our supportive and challenging environment is here to help you grow. Discover your potential—join us!
