Re: Tenshin Aikido
My last knowledge was that Reynosa Sensei in Ventura and Matsuoka Sensei in Irvine (Ikazuchi Dojo) in Irvine were no longer with Tenshin or Seagal, and are both excellent teachers.
Tenshinkai, totally different, is at the Westminster Aikikai (Orange County) under Sensei Dang Thong Phong. See the Aiki Expo tapes for a sample. Extremely excellent. Worth taking a look. Tell anyone there I sent you.
