As I have an advanced degree in an unrelated field, the Dr. was especially careful to avoid the appearance of being condescending to me. He asked a few times if he was using clinical language I did not understand but his tone was informational.

Having moved here recently from another area and for a number of years of having been there and receiving excellent care, I was reluctant to meet with another doctor. Dr. LeMasters was extremely thorough and I was impressed in all respects with the time I spent with him. I would highly recommend him to others and would be completely confident of any future care needed for myself with him.

I don't appreciate after telling a DR about a problem that while an examination he raises his voice.. He was shinning a very bright light into an eye with a caterac which was giving me some problems. I squinted, he raised his voice and said don't fight me{illegible or inappropriate content} Who the heck does he think he's speaking to. I won't put up with that kind of behaviour from someone who I'm supposed to trust{illegible or inappropriate content} Guy acted like a jerk{illegible or inappropriate content} Next year I may just try the new Eye clinic that opened in Shamokin.. I heard they trat there patients with respect and dignity{illegible or inappropriate content}

Dr LeMasters is a very busy man but you never feel that way when he is explaining things to you. He takes his time and makes sure that your questions are answered. He also doesn't let you leave without asking again if there are any questions and if you understand everything about your appointment.
