I could not be more impressed or thankful that I met Dr. Flannery and his team when I happened to need their specialization the most. After a misdiagnose from another hospital months before that created an urgent situation for me at an ER, Dr. Flannery quickly diagnosed my problem and told me what needed to happen and why. It was an urgent situation and I will be forever grateful that he was the surgeon that I met with that night. His entire staff has been tremendous during the surgeries and the care in between. I cannot recommend Dr. Flannery enough.

I would like to thank Dr. Flannery for quite literally changing my life. Colon resection surgery was something that had never entered my thinking so when it was decided that this is what I needed I was pretty nervous. But Dr. Flannery and his staff put me at ease by patiently answering my questions and concerns. I also felt very comfortable knowing he had been voted Best Doctor for so many years in a row. That was extremely reassuring to me seeing all of those plaques on the wall !!! All of my nervousness was a complete waste of energy. How fortunate I feel to have such a competent surgeon in our area. Thank you Dr. Flannery and your entire staff.

Just a heads up to potential "preventative" colonoscopy patients. Make it clear you are there for preventative and not diagnostic, which I did. However my billing code was changed to diagnostic without me knowing due to questions asked prior to procedure in which I stated several times "not a problem". Also, the Dr. never told me he had concerns about anything we discussed prior to the colonoscopy and did not alert me he was changing it to diagnostic. No polyps were found as well which change your coding. The doctor was fine for procedure and it was uneventful. His staff is fabulous. After receiving the bill I contacted the office and it took over 3 months to get a "final" decision that they would not resubmit the code as preventative. So almost $2,000.00 later when it was supposed to be a preventative colonoscopy covered in full by my insurance, here I am. Hopefully my "lack of knowledge" to just say nothing prior to the procedure will be helpful to someone so they don't go thr

Very professional and knowledgeable. I had Diverticulitis, and had multiple attacks that landed me in the emergency room and was admitted 3 different times. After the 3rd attack, I met Dr. Flannery. At that point we planned out my surgery. Dr. Flannery and his PA-C Beth Neuhardt, answered my numerous questions about prep, the surgery itself, and what to expect after. Dr. Flannery and his staff were very accessible, which made me feel more at ease. I had surgery 10 weeks ago today and everything went as planned. I feel great!! I highly recommend Dr. John Flannery and his staff!

A 6th star needs to be created for Dr. Flannery. He was nothing short of remarkable in every way. Both he and Beth always made me feel like I was their priority. Dr. Flannery thoroughly explained every aspect of my pre through post surgery experience. He eased my anxiety and I always felt that I couldn’t be in better hands. It was a blessing that I found him and couldn’t imagine having a better doctor.

Dr. John V. Flannery, Jr. is the consummate professional. While very focused on my surgical needs, he was very accessible, thoroughly explaining all aspects of my surgery. Dr. Flannery was able to complete my colon resection surgery laparoscopically, avoiding the complications of open surgery and shortening my recovery time. He always listened intently and responded to all questions--from both me and my family caregivers, putting us all at ease. I felt like I was his top priority. Dr. Flannery, his knowledgeable PA-C Beth Neuhardt, and their exceptional support staff were there for me through my hospitalization and home recovery. I am so fortunate to have found Dr. Flannery and I highly recommend him to anyone needing colorectal surgery.

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

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
