Dr. Anthony Costella

Dental practices in Marin County range from large group offices to solo practitioners, each offering a different approach to oral care. Dr. Anthony Costella operates a dentist’s office that fits the latter model, providing individualized attention without the scale of a multi-provider clinic. Routine cleanings, fillings, and preventative care form the core of what’s available, alongside services like crowns and bridges for those needing restorative work. The practice also handles basic extractions and periodontal maintenance, covering the essentials without branching into cosmetic specialties.

Finding the office is simple for anyone familiar with San Anselmo’s stretch of Sir Francis Drake Boulevard. It sits at 1600 Sir Francis Drake Blvd, a few blocks west of the downtown core but still within easy reach of central amenities. Parking in the area follows the usual rules for this part of town, with street spots and small lots serving businesses along the corridor. The location puts it a short drive from both Fairfax and Greenbrae, making it accessible whether you’re coming from the hills or the highway.

Patient feedback so far has been uniformly positive, with a 5.0 rating drawn from 2 reviews on Google—though the small sample size means impressions are still forming. For those who prefer to confirm details by phone, the number is (415) 453-0642. As with any dental practice, it’s wise to verify accepted insurance plans or payment methods in advance, since policies can vary even among general dentists in the same area.

First-time visitors might want to check the map for exact positioning, especially if arriving from the Ross or Kentfield side: directions are available here. The office’s placement along a well-traveled route means it’s easy to spot once you know the landmarks.
