I am well taken care of at Spectrum Eye @ Good Sam from the moment I arrive. Staff is attentive, courteous, caring, friendly. I was particularly impressed at how kind and complimentary Dr. Mastman treats staff, and of course, patients. He is quite knowledgeable, an excellent educator, calm, competent. With a variety of onsite equipment, it is easy to get quick answers & solutions, whereas in previous ophthalmology offices it would have meant going for additional tests elsewhere.
