ON WEDNESDAY, JAN 9. Part 2 of Rock's Basic Self-Defense series. We're very excited about this episode. Why? Because the guest speaker is one of our favorite people, and one of our favorite Sifus. Keith Sheppard, or "Shep" has been teaching martial arts for over 20 years in the largest and longest continuously-running martial arts school in the bay area. Shep has also trained as a boxer, alongside fellow teacher, Ana Julaton (Women's WBO Super Bantamweight and IBA Super Bantamweight Champion and student of Freddie Roach).
