I am Ernest V. De Guzman, a physician who specializes in the psychiatric evaluation, complementary therapy approach, and medical management of an individual who is suffering from mental illness. I provide services and maintain a private practice in San Diego, California.

With over seven years of experience as a Psychiatric clinician, I have treated the full range of mental illnesses, and am currently serving a broad spectrum of patients. I have been entrusted with the care of individuals with inherent and developed behavioral problems, the severely and persistently mentally ill, those with a combination of substance addictions along with mental illness, active/retired military and/or their dependents (this in particular resonates with me having been a former military dependent myself), elderly with behavioral problems, monolingual non-English speaking people through the use of interpreters, those with work related behavioral issues, and in general people between 18 to 65 plus years of age.
