I have been going to Diablo Valley Optometric for decades. It is not the cheapest place, but, to me, glasses are a big investment. I want them to look good on me and last. The staff is very talented at finding what works for you. They are informative, conscientious and quick to help you be a happy customer in any way possible. Doctor Ottati is very attentive, honest, kind and professional. I highly recommend them!
