Andrew Nisbet, 32, faces a total of 75 felony counts, including oral copulation by force, lewd and lascivious acts with a minor, distribution or exhibition of lewd material to a minor, and arranging a meeting with a minor for the purpose of engaging in lewd and lascivious behavior.
The alleged victims are boys between the ages of 12 and 17, according to Livermore police.
Nisbet is being held without bail at the Santa Rita Jail in Dublin. He is scheduled to return to Alameda County Superior Court on March 26 for a pretrial hearing.
The golf pro was arrested Dec. 7, shortly before he was to receive the 2013 Junior Golf Leader Award from the PGA's Northern California Section.
PGA officials lauded Nisbet "for his dedication and leadership in developing a wealth of exciting and educational golf programs for juniors."
Nisbet, who taught at Livermore's Las Positas Golf Course, was fired after his arrest. For the past five years, he also helped run the U.S. Kids Golf World Championships in Pinehurst, N.C.
Police have said they suspect him of abusing boys in other areas of the country. No additional charges have been filed to date.
As a result of Nisbet's arrest, the Tri-Valley YMCA held a forum in December on recognizing the signs of sexual abuse. A second forum, focused on preventing sexual abuse, is in the works but no date has been set.
