Aikido of Ramapo Valley is a noncompetitive martial arts training facility in Wyckoff that has been in business for 12 years. Aikido is open to men, women and children of all ages. Founded on the principle of harmony and nonresistance, Aikido doesn't rely on size or strength, but rather it uses the energy of the attacker for self-defense. The main trainer at the facility, Eran Vardi Sensei, has been practicing the art of Aikido since 1989.
