Serving the Mountain View community
Mountain View is about 10 minutes west of our office along El Camino Real or Central Expressway. We treat patients from across Mountain View — Googlers from the Shoreline campus, NASA Ames researchers, families in Cuesta Park and the Old Mountain View neighborhood, and downtown professionals near Castro Street. Many of our Mountain View patients are referred by El Camino-area general dentists for retreatment of older root canals, microsurgery on persistent apical lesions, or evaluation of cracked teeth that need imaging the general office doesn't have.
