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 surgery. Dr. Giammar's work is outstanding as well! If you're looking for a surgeon who is top notch, look no further; Dr, Giammar is your guy! Five Stars!

Upon my first meeting, I liked dr. Giammar. He performed my surgery that ended up being a catastrophe. The morning after my surgery he went on vacation. I ended up with a terrible infection, and in a nursing home. Dr. Giammar's staff acted like high school bullies with me-and the staff from the nursing home. I went to the dep't head for help. He had me see dr. G again. Dr G was sarcastic, and manhanhandled my drain and wound. Can't believe he's back and practicing again. Awful! The worst!

Be positive that all procedures are necessary. Not just a band aid or patchwork. He did a surgery that should have not been done in hindsight.

I was assigned Dr Giammar from an emergency room visit. I found him to be very pleasant to work with and seemingly very knowledgeable. The surgery was easy. My problem is that his office has sent me to collections for a bill my insurance company (Allegiance) says I am not responsible to pay. Allegiance does not think they are responsible either. Putting the client in the middle of this situation is both immoral and unethical. It is probably also illegal. If this is done to elderly also.

HIS PERSONALITY SKILLS AT THE TIME OF INITIAL OFFICE VISITS WERE FINE. I SCHEDULED SURGERY WITH DR. GIAMMAR BASED ON HIS EXPLANATION OF HOW SUCCESSFUL HE THOUGH THE SURGERY WOULD BE. I WAS EXTREMELY DISSATISFIED WITH THE OUTCOME OF THE SURGERY AND HIS FOLLOW-UP CARE WAS NONEXISTANT. THE SURGICAL RESULTS WERE SO BAD I NEEDED TO HAVE ANOTHER SURGEON OPERATE ON ME SIX MONTHS LATER TO REVERSE THE SURGERY. DR. GIAMMAR ONLY ENTERED MY HOSPITAL ROOM TWICE AFTER SURGERY & NEVER TALKED WITH ME!!

Unfettered access. Excellent care. This doctor goes the extra mile and DEMANDS that staff caring for his patients do the same. Exceptional and worth the difficulty and wait in locating.
