He didn't want to treat and honor my appointment and talk with me I ask to see and talk with him and the lady I could not. She was not the Doctor but she said I couldn't see him. So I left the office. I never experienced anything like I did from supposed to be a professional nurse or aid not sure of her title or name. She always check me when I see the doctor.

Very courteous, very understanding. Listen well and always have good positive comments to give his patients. I'm very proud to be a patient of Doctor Michael Dionne. Any I will any always seems to act like he's very concerned about his patience. So I am very glad that he acts that way towards me because the loudest times I've made. Be a little depressed. He takes the time to listen and I'm just thankful and I think thank you for the survey.

Doctor Dion is a very patient-doctor he listens. He takes the time to explain. If he does not understand what the patient is saying, he sits down with them and have them to specify everything that they want. I mean, I have always been patient. Up here as always, will be a patient piece. With recommend anybody to go and see him because he listens to his patience. He sits down. He takes the time to understand what expectations is saying. He takes the time to understand what his patient is warped. And it is a joy to just be around him to see what he's doing
