Medical Board of California Revokes License of San Francisco Psychiatrist Convicted of Possessing Child Pornography

Published: Thursday, January 31, 2019

(Sacramento, California) - The Medical Board of California (Board) has revoked the license of a San Francisco psychiatrist who was recently convicted of possession of child pornography.

The revocation of the license of Billy John Lockhart became effective on January 30, 2019. Lockhart worked as a psychiatrist at the University of California San Francisco's (UCSF) Psychiatry Department and uploaded and traded over 600 images of child pornography online, sometimes using the USCF's Wi-Fi network to trade the images.

"The crimes that Lockhart was convicted of are egregious," said Kimberly Kirchmeyer, the Board's Executive Director. "The revocation of Lockhart's license meets the Board's mission of consumer protection."

The Board's accusation against Lockhart charges him with conviction of a crime, unprofessional conduct, and failure to report an indictment or information and conviction.

To view the decision against Lockhart visit his physician's profile page on the Board's website. For more general information about the Board, including how to file a complaint, visit its website at
