Search Continues for Victims of Alleged Fake Doctor

Richmond man arrested for practicing medicine without a license after claiming to be an oncologist.


A Northern California man will appear in Ventura County Court on October 26, 2015, to face felony charges of the unlawful practice of medicine and elder abuse, and a misdemeanor charge of furnishing dangerous drugs without a license.

Vincent Gammill, of El Cerrito, allegedly charged a cancer patient $2,000 and promised her a cure. He then furnished her with expired pharmaceutical medications and dirt.

Gammill, the owner of the Natural Oncology Institute in Richmond, claimed he was an oncologist, but has no license to practice medicine in California. Gammill was arrested on July 9, 2015, after a search warrant at his home and office turned up laboratory equipment, bottles labeled “corrosive” and “poison” and more than 25,000 prescription pills including morphine, Ambien, steroids and Mexican and Russian drugs.

On August 31, 2015, Gammill pleaded not guilty to all charges.

The investigation was a joint effort between the Contra Costa County Sheriff’s Office and the Ventura County Interagency Pharmaceutical Crimes Unit (PUC), a task force that consists of law enforcement officers from the Ventura County Sheriff’s Office, Simi Valley Police Department, the District Attorney’s Office, the California Highway Patrol and the Department of Consumer Affairs’ Division of Investigation’s Health Quality Investigation Unit.

More victims are being sought. Southern California residents may contact the PUC at (805) 383-8700 or email Northern California residents may contact Contra Costa County Sheriff’s Office at (925) 313-2600.
