He performed my surgery and there were complications. He was very rude and condescending and trivialized my symptoms. I do not recommend this doctor.

I trust Dr. Giammar. Dr. Giammar always goes the extra mile. When he wasn’t able to help a family member he found a doctor who could. I like that he pays attention to detail and remembered my birthday!

Dr. Giammar is hands down one of the best surgeons I have had the pleasure of having as my colorectal surgeon! He takes the time to put the patient first, and to listen to all questions and concerns. He is very personable, and knows how to ease your mind, and the mind of your loved ones before...more
