"Dr. Cartago and his staff are always extremely hospitable. Their friendliness in the office as well as on the phone, makes it easy to return. Their office is comfortable and modern with a big-screen TV, computer-access, and nice snacks (coffee, water, cookies). The work that they have done for me (cleaning, xrays, fillings, and a crown), have been relatively painless. I strongly recommend Dr. Cartago and his staff in the San Ramon Office." - Shelley London.
