Medical Board of California

An American Canyon physician, Susan Ann Pereira, M.D., faces disciplinary action by the California State Medical Board after being accused of unprofessional conduct.

Pereira, who specializes in internal medicine, also faces charges based on a criminal conviction and dangerous use of alcohol, said medical board documents.

The charges, filed on June 25, stem from a May 2017 incident where Pereira was arrested for driving under the influence of alcohol and having a blood alcohol content (BAC) in excess of .15 percent.

On Monday, May 1, 2017, at about 5:12 p.m., a witness reported Pereira, driving a Cadillac Escalade, had run three vehicles off Highway 29 in American Canyon. She claimed to have consumed two glasses of wine, between 1:30 and 2 p.m. that day, the medical board said.

Her preliminary blood alcohol screening tests registered .18 and .19 percent.

In November 2017, Pereira pleaded no contest to driving with blood-alcohol in excess of .15 percent. She was sentenced to five days in custody, three years of probation, 40 hours community service and a $1,723 fine.

Pereira could not be immediately reached by phone or email this week.

According to the Department of State Hospitals, Pereira has been employed at Napa State Hospital since March 2015 as a physician and surgeon.

According to the California Medical Board website, the California state board issued her physician’s and surgeon’s certificate in 1999.

Pereira faces possible disciplinary actions include revoking or suspending her license, revoking her authority to supervise physician assistants or placement on probation.

The California Medical Board oversees doctors’ licenses in the state, including the more than 400 medical doctors in Napa County.
