November 17, 2012


November 12, 2012

I believe that the aftercare was not intentionally forgotten. We had gotten off topic and it slipped everyone's mind. However, I did call to find out the following day and waited for a return call, with none forthcoming. I had to call back a second time, and at that point after a several hours had passed, I had to get to work, and left home without cleaning the wound properly.

Dr. Duffy was superb!

I would recommend to my friends and family these providers.
