About this record

Verified Injector builds this page from three sources: the websites of the clinics that name this clinician, the federal NPI Registry, and the California licensing board. It reports what those records showed on the dates stated.

It is not a rating of clinical skill, treatment quality, safety, reviews or patient outcomes, and a current license means a board has not withdrawn one. If anything here is wrong about you, tell us and we will correct it free.
