Sensei Fairfield began his Jujitsu instruction in l963 at the Island Judo / Jujitsu Club. He was hired as a teacher and coach at Alameda High School in l964. During his tenure at Alameda High School, Sensei taught biology, physiology, was a counselor and physical education teacher.  He
coached swimming, water polo, and tennis.   In l975, the Alameda High School physical education department was told that the gym would be unavailable as a teaching station, due to earthquake renovation, and the instructors were asked to "improvise a program for a year".  We were given a dingy room in the basement of the cafeteria.  Sensei Janice Okamoto
was in Sensei Fairfield's first class.  Jujitsu evolved over the years to  become one of the finest physical education programs in the history ofthe Alameda School District..  The Juitsu class was voted the best Physical Education class in the San Francisco Bay Area.  The class was invited to demonstrate at two State of California Teachers Conventions, and at the National Secondary School Teachers Convention. Alameda High School students participated at the Henry S. Okazaki National Championships.  Sensei's David Fairfield, Ron Beatty and Janice Okamoto were the founders of Camp Danzan Ryu, held each year in Felton, California.

Sensei was voted "Teacher of the Year" in l984 for his work with the Jujitsu program, the only physical education in the 125 year history of the Alameda Unified School District to receive this award, and was the North Coast Section Honor Coach of the year in l985.
