Patient Testimonials

Dr. Weinstein performed the LASIK procedure on me a few years ago. The results have been absolutely incredible. Ever since the procedure, I have seen 20/20 with no side effects. I hold the highest regard for Dr. Weinstein and his practice.

I have been seeing Dr. Weinstein for 25 years and he saved my eyesight.  I had laser treatment for bleeding blood vessels and a cataract removed. He is the most compassionate man. Thank you Dr. Weinstein for all of your hard work.
