Leslie Cohen


Leslie began training in 1988 with Jerry Paup Sensei and the aikido club at UC Santa Cruz. From her first roll she was hooked and began training as much as possible, also joining North Bay Aikido under Linda Holiday Sensei. In 1990 she traveled to Shingu, Japan to study with Hikitsuchi Sensei. Soon after her return to San Diego in 1991, Leslie became the student of Chiba Sensei at San Diego Aikikai. She feels immensely grateful and fortunate to have been able to train with him until his retirement. As a Stay-at-Home Mom to her two children, she spends a lot of time volunteering at their school. Leslie also leads the Scripps Ranch Zen Group.
Under Chiba Sensei, Leslie is ranked 6th dan and Shidoin certified.
