Our Story

In 1973, Drs. Albert Abrams and Raymond Melrose established USC Oral Pathology Laboratory, a biopsy service within the University of Southern California, School of Dentistry. Oral Pathology Associates, Inc., was formed in 1997, after the founders retired from academia.  We are now a private biopsy service. Oral Pathology Associates has become one of the largest oral pathology practices in the Western United States. The organization has accumulated over a quarter of a million accessioned specimens which constitute one of the largest and most well documented teaching and research resources in North America.

Oral Pathology Associates has an active roster of over 5,000 dental and medical practitioners from 15 states that use the service to provide care for their patients. Total contributors exceed 11,000 practitioners. These contributors include practitioners of general dentistry and medicine as well as specialists including endodontists, periodontists, oral and maxillofacial surgeons, pediatric dentists, otolaryngologists, and medical pathologists.
