I have gone to Dr. Guastella for a few years now. When I last went to Kellogg Eye Center in Ann Arbor Michigan, which is a part of the University of Michigan, I was told they could no longer correct my vision. I talked to Dr. Guastella about my eye condition, he informed me that he was proficient in diabetic eye. Since I am diabetic, this was perfect. He has since treated my eyes and has done a magnificent job. I highly recommend him to everyone looking for an eye Dr.
