I am located in the San Francisco Bay Area.

I have qualified as an expert in forensic science disciplines in many Superior Courts in California and in the Federal District Courts.

I am the former Director of the San Francisco Police Department Forensic Services Division.

I am a member of the American Academy of Forensic Sciences, the California Association of Crime Laboratory Directors, and a past-president of the California Association of Criminalists.

Please note that by policy, I do not accept cases directly from individuals who are involved in the case, or cases that are being handled pro per.
