Patient Comments (10)
in Columbus, OH |
I had a routine appendectomy but ended up developing gastroparesis after and was sick for two months until another doctor diagnosed the condition. Dr. Giammar was rude and dismissive to me at my subsequent office visits and made me feel intimidated. I will never recommend him to anyone!
in Urbana Ohio |
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.
in New Lexington, OH |
I have been a patient of his or about 12 years he is my hero wou;dn't trust anyone else , like he said i have i 9 life's as long as he keep saving me that's good ...... Thank you so much for all you have done for me and continue to do your the best !!!!!!!
in New Albany, OH |
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.
in Bellefontaine, OH |
Very compassionate and caring. Treated my elderly mother ever so gently. Wonderful to the family.
in Mount Vernon, OH |
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!!
Columbus, Ohio |
Dr. Giammar has wonderful bedside manner that for surpasses your average surgeon. He answered all my questions and was very positive and encouraging about my recovery from surgery. Kind, thorough, excellent.
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.
Indianapolis, IN |
Caring and took the time to listen to me. Hard to find, but worth it.
