I have been going to Dr. Costigan for over 15 years. The staff are always friendly and the office spotless. Dr. Costigan recently replaced my 4 front teeth with 1 implant and 3 crowns. I am overjoyed with the outcome. Dr. Costigan is not only skilled and meticulous but very gentle. I highly recommend this business!

At the end of my appointment I was virtually attacked by the dentist who went off and how she hated illegal immigrants and the fact that they are going to be taking money from America requesting healthcare it was out of nowhere and when pressed she became more and more racist I cannot support a business that feels this way

They are my lifetime dentist! I absolutely positively 100% trust them AND REALLY ENJOY COMING! I have to get my teeth cleaned every 3 months for now and I have had a lot of dental work overseas. I found this gem San Marin Dental after I got back an needed a crown on my tooth. I have been going every couple of months now. They are always SO nice and accommodating! Dr. Costigan has become sort of a mentor now at this point! She pointed me in the right direction for dental insurance and braces recommendations. Denise is my FAVORITE HYGENSIST ever! I love coming to get my teeth cleaned which I never

I love Dr. Costigan and her entire staff. I'm sad to say that due to insurance reasons I will have to find a new DDS.
Dr Costigan has always been understanding and compassionate with regards to budgetary concerns, working with patients to utilize insurance most efficiently. She is honest and realistic in her assessments of which treatments are necessary and which can be put off or avoided with proper home-care.
Camille is the single greatest Hygienist I've encountered. The new hygienist is great, and I found her every bit as gentle and effective as her counterpart, but Camille has an
