I knew nothing about martial arts, let along aikido, but was interested in the technique and dropped by the Aikido Institute of SF out of sheer curiosity. Little did I know that I would be welcomed into the dojo with such warmth and encouragement from the other aikidoka and the instructors. The fluid yet strong movement and the principles of aikido - non-aggression, non-competition - have kept me coming back to this practice. The monthly dues (around $100) are an incredible value for the knowledgeable, patient, and dedicated instruction you receive.
