“As a patient of Dr. Iskander’s, I feel that he, and his staff, gives me and my family the proper care with great compassion and understanding. I am welcomed by the warm smiles in the office and never feel intimidated. Dr. Iskander provides the best quality care with such thoroughness which I truly appreciate. He takes care of me through the entire illness. Needless to say, my family is very pleased to have Dr. Iskander and St. Mary Internal Medicine as our family doctor and clinic.”
