A Sonoma physician accused of inappropriately prescribing controlled substances to four of his patients surrendered his license on May 1 to the Medical Board of California.

According to a press release from California’s State Medical Board, accusations filed against Clinton Lane, 76, charge him with four counts of unprofessional conduct for repeated negligent acts, and/or excessive prescribing, and/or prescribing without an appropriate prior examination/medical indication.

At a meeting with the Attorney General of California last month, Lane reached an agreement to surrender his medical license, without admitting to the charges, according to a spokesperson for the state Medical Board. He did, however, admit that there was a factual basis for the charges.

Based on a timeline of the investigation and filing processes of the state Medical Board available in its annual report, the complaint against Lane was launched well in advance of the announcement of his retirement in 2018.

Lane practiced internal medicine in Sonoma for more than 40 years, most recently out of a practice at 377 Perkins St. He was also affiliated with Sonoma Valley Hospital, and served as its medical director.

The Board’s accusation against Lane outlines “a pattern of repeated negligence involving the prescription of opioids to four of his patients,” according to the press release.

Lane retired from practice in Sonoma last April and at that time, told the Index-Tribune that after retirement, he would be spending half his time in Thailand and half in Glen Ellen at two-month intervals.

Lane grew up in Marin County, was an undergrad at Stanford University and earned his medical degree at UC San Francisco.

His first position in the Valley was at the Sonoma Development Center, and he built a home in Glen Ellen where he has lived since 1976. He started in private practice a few years later.

Lane was also the medical director of Valley of the Moon Hospice in its early years and continued on to serve on the board operating council at Hospice by the Bay. He is retired from that position.
