Dr. Santiago is excellent! 3 years ago I was experiencing a lot of frustration with my contact lens prescription. A friend recommended Professional Eye Care Center in Niles. After my appointment with Dr. Santiago, I knew that I would not be going back to my prior eye doctor and that I would definitely be staying with him! Dr. Santiago is professional, knowledgeable, and personable! He made sure that my contact prescription was the best it could be after trying out several different lenses and prescription combos - I really appreciated his patience, efficiency, and determination to find me the right fit!
