Rosann R:  My daughter and I went to three different places to purchase eyeglasses…When we went to the Vision Center, Daniel helped us order the Rayban lenses for $140.00! They had the best customer service! I would highly recommend going to speak to Daniel he was A A+ !


Kevin C:  The new office layout looks great and has streamlined the waiting process at the busy Santa Maria location. I would highly recommend him to everyone in the Santa Maria/ Five Cities areas!  My wife, kids, and I have been patients since 2003.
