Check us out on the web at portsmouthaikido.org In 2009, Ringer Sensei transferred her titles of Chief Instructor and Owner of Portsmouth Aikido to Aaron Cass.
Under Cass Sensei’s leadership, and with the help of Ringer Sensei and their senior students, Portsmouth Aikido transitioned into a 501(c)(3) educational non-profit organization. Our hope is that with this new model we are better able to serve the New Hampshire seacoast community, continuing to expand our membership and offer excellent instruction.
