Bio

I completed medical school at Loma Linda University in 1988 while teaching anatomy for the dental and physical therapy students and serving as the social director for the class. After an Orthopedic Surgery internship in 1989, I completed a Pathology Residency at University of California—Los Angeles in 1993. After doing advanced training in Cytopathology, I joined the United States Navy (CAPT, MC, USNR). With triple Board Certification in Pathology, I worked for a decade at the Armed Forces Institute of Pathology, Washington, DC, developing a specific interest and expertise in pathology of the Head and Neck and Endocrine organs. During this time, I served as Chief of the Division of Otorhinolaryngic-Head & Neck Pathology, Chief, Division of Immunopathology, and Assistant Chairman, Department of Scientific Laboratories. I have published over 160 research papers, currently serving as the editor of Head and Neck Pathology; teaching at national and international conferences; serving as an active member of a number of national and international societies; and collaborating on the World Health Organization’s books for Head and Neck and Endocrine Organs. I have published 4 books (Head and Neck Pathology; Endocrine Pathology, Churchill Livingstone-Elsevier; Diagnostic Pathology and Molecular Genetics of the Thyroid, Wolters Kluwer – Lippincott Williams & Wilkins; Diagnostic Pathology: Head and Neck , Lippincott-Williams Wilkins). I enjoy cooking, stained glass, cake decorating, SCUBA and travel.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
