The electrician showed up on time. He was courteous and explained the options to me. He departed and returned with the necessary appliance. He installed it efficiently in a difficult location. I expect that I will ask Thornton to install a similar appliance in January, after the holidays are over.

Dr. Lai, Mitch and the team are awesome. Easily the best, most caring optometrists I ever had - I came here many years ago, and never left. Come ready for a consultation that will be thorough, with state of the art technology but also a great compassion and caring for you as a person, like in the old days.
