Aftet s eing multiple doctors who all said my only option for pain relief was a Hemorrhoidectomy I sought the option of Dr. Flannery. He resolved my embarrassing condition in two 10 minute office visits! Dr Flannery saved me from a seriously invasive procedure. I highly recommend him!

If anyone I know ever needs colorectal surgery, I will send them straight to Dr. Flannery. I am originally from the Boston area and considered seeing a surgeon in the city. After meeting Dr. Flannery, my husband and I felt very confident in his knowledge and skills. He explained the surgery in detail, answered all my questions and concerns. I felt no need to follow up with another opinion. I had 10" of my sigmoid colon removed. I felt Dr. Flannery was very compassionate, attentive and conf

I had a colon resection, Dr. Flannery was excellent. Surgery was done laparoscopically, no colostomy. Very happy with the results.

If you are reading this review, then you are in a sensitive state about a sensitive manner. Something private. A subject that a lot of us know, but do not like to discuss. But I recently turned 50 and a colonoscopy screening was at the top of my list. To my surprise an issue was found and I was referred to Dr. Flannery's care. That recommendation was one of the best I have ever received. Upon meeting Dr. Flannery he a is a very warm and caring individual and has empathy like no other doctor I ha

Dr Flannery is a wonderful doctor! I have seen him in a few occasions and each time he was able to immediately diagnose my issue . He performed my first colonoscopy. He is VERY knowledgeable and listens to questions & concerns. I have never felt rushed during any of my office visits. I highly recommend him!

In April, I had my first appt with Dr. Flannery. I am a Chron's patient who developed a fistula that required surgery. All points of visit/surgery/aftercare were top notch. I knew what was going on and what to expect at all times. Recuperation went without a hitch and everything turned out well. I know that my condition will probably require future surgeries and I have no problem having Dr Flannery as my surgeon.

Dr. Flannery most likely saved my life when I was diagnosed with diverticulosis last October. Since I had serious intestinal infection, he had to do everything necessary to stop that process and set me up for healing. Having done an excellent surgical job (twice), I am now on my way to being healthier than I have been for a long time. I highly recommend this doctor to anyone with intestinal problems.

Dr. Flannery was recommended by my family doctor and I have to thank my doctor for that. I needed an opoeration (Colectomy) to remove part of the colon. Dr, Flannery explained the entire procedure prior to the operation and the opperation was a success. I highly recommend Dr. Flannery without any reservation. His expertise and knowledge in this area is the best. I might add that post-op visits were timely and that recommendations made for my recovery were easily understood.

Dr. Flannery is competent, confident, caring, and thoroughly listens to the patient. He performed lower colon surgery to remove a cancerous mass in a difficult position and got it all removed such that cancer treatments were not necessary. His staff is outstanding making office visits or phone communications easy. He is an excellent doctor and caring person that I recommend to anyone.
