    Dr. Herbranson graduated with a DDS degree from Loma Linda University in 1970 and a MS in Endodontics from Loma Linda University in 1973. He has practiced endodontics in the East Bay since that time.

    He has been actively involved in education for years, having given many lectures locally and nationally on endodontics as well as presentation skills and microscope photography. He is on the faculty of the University of the Pacific School of Dentistry and lectures at Loma Linda University School of Dentistry. He is an Opinion Leader for a major endodontic supply company and helped develop their corporate education protocols. 

    He is nationally recognized in the endodontic field and his interest in photography has resulted in the creation of a small company that builds camera mounts for surgical operating microscopes.  Another of his interest is the development of a computerized atlas of the anatomy of human teeth.  It has been recognized as a significant tool in learning the complex microanatomy of teeth and is currently being adapted by many dental schools in the United States.  It can be viewed at www.toothatlas.com
