Dr. Brennan removed my gallbladder over one year ago. He was referred to me by a friend (colleague) who had personal experience with his surgical skills. I was, and continue to be, very happy with the results.
I, myself, looked through Dr. Brennan's reviews to see if others recommended him as well before my surgery so I decided to write my own review. Dr. Brennan performed a scheduled cholecystectomy (gall bladder removal) for me and it could not have gone any better! I was so nervous/scared/anxious as this was my first surgery ever and I am only 19.. but he reassured me he would do his absolute best and I was in safe hands. He did an amazing job with a very quick recovery! He did not let me down!
Horrible. Don't go to him!! Did a junk by-pass with artificial vein which caused massive infection. Then gave up on the leg. Didn't care. Leg saved by another surgeon, not UHS based!
Over the Christmas holidays my husband became ill with what we thought were heart issues.Fortunetly this wasn't the case. It was gallbladder problems. Dr. Brennan didn't hesitate and insisted the surgery be done on Christmas Day. His bedside manner was personable and his surgical skill enabled my husband to be back home in a matter of two days. I would highly recommend this fine man and I sincerely thank him for his care of my husband.
Dr. Brennan is compassionate, courteous and able to answer all my questions and concerns. I am glad he was the surgeon chosen by my team of doctors. Thank you, Dr. Brennan and The Lord Bless you. I am unable to answer three of four questions in the first part below as I was treated by Dr. Brennan while in hospital. I dealt with his staff on the phone after my chemo treatments were done.
Doctor Brennan is a wonderful and caring doctor. He saved my dad's life on October 10, 2015. My dad was rushed to surgery for an emergency abdominal aortic aneurysm. His aneurysm was beyond the point of a minor repair and we were told the risk of him NOT surviving was great. While in surgery the aneurysm ruptured but Dr. Brennan was able to save his life. I cannot praise Dr. Brennan enough for all he did for us, his knowledge, wonderful bedside manner and overall treatment he gave to my dad. He
He acted like I wasn't really in pain.treated me as if i didndidn't know what I was talking about.after surgery he was an ass.yeah he gave me something for pain.but a few days later when he said i could double up on what he gave me for pain..then two days or so after surgery I was on my own.he doesnt want to help.so I'm left having to get out of pain on my own.so thanks a lot Dr Brennan hope you enjoy getting drunk in your off time.I'll be waiting to call the cops and happily be sure u get a dwi
