Everything in Dr. Zanger’s office makes a patient realize what it is like to be treated by top quality doctors, and an excellent well trained medical, and office staff.Professional in demeanor, exceptionally competent, and yet both polite, and friendly make up some of the words I would use to describe the Drs. , and the staff.Our Gloucester community is extremely fortunate to be served by such a proficient, top notch Ophthalmologist, and his staff.
