I have no complain what so ever. I ave friends and relatives that had the same type of surgery I had, I feel bad for some of them. Their scars are terrible, as for me, I have to really strech my skin in order to see anything, I mean barely anyting. I thank Dr Demers every day for that. I probably going to have a second surgery and I am hoping tha Ican scedule it with Dr Demers. I lie him a lot. He is very reassuring and does ecxactly wha he said he was going to do.

Dr. Demers is a very compassionate surgeon. He explained options for my breast cancer surgery in a manner I could easily understand. He answered all my questions & equipped me with the information I needed to make an informed decision as to the type of surgery I would choose. I'm extremely thankful to Dr. Demers & his staff for their standard of care. I would recommend Dr. Demers to anyone with a breast cancer diagnosis.
