*Dianne and I have a good, long term patient/doctor relationship.


I hope *Diane never retires and I told her so!


She explained so well and listened carefully. She understood what I wanted to say and my concerns.


Di is so kind and gentle and compassionate! I'm lucky to have her as my provider


she was so personable and made me feel extremely comfortable throughout my entire visit. she listened to every question and patiently answered them all. I will definitely be going back!


*Di is the best. I would recommend her to everyone that needs her.


Di has always been a thoughtful listener. She respects me and I know she cares about me as a patient and person.


Even though She has been in this position for years, she is still helpful, friendly and informative. She didn't run out of the room after 12 seconds. A good doctor.


Diane was amazing, I felt so comfortable with her. I like that she took some time just to chat and get to know me before diving in to the appointment.


The best listener and communicator! I avoided going to a doctor for many years because they typically do not care'. Dr Nagy not only truly listened, she actually read into things I was saying and ended up treating me for an additional.
