Mark Brennan

Dr. Brennan is a fine surgeon. I've had 3 surgeries in two years. He and his staff explained everything before and after. They really care about my well being. Highly recommend him!

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.

I highly recommend Dr. Brennan, I have had two successful surgeries through him. Both him and his staff are wonderful. Very professional 5 out of 5.

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 was extraordinary not only with my dad but with me and my entire family. I couldn't ask for better care or for a better doctor! Thank you Dr. Brennan!! THANK YOU!!!

M.B. stands for Muthaf@&kin Butcher, do not entrust yourself or your loved ones care to him. he has a laserlike focus on cutting people up with little care for safety or accuracy. i as a patient gained first hand mistreatment. also, i have been informed about him from his subordinates and coworkers.

Rushed. Little confidence. Judgmental.
