Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Did not prescribe any lab tests
He simply listened to my opinion on my condition .. prescribe drugs and let his aide take over in a few weeks. Still had colitis and his aide just said take Imodium. I cancelled next appointment and will not return to your practice j.alden

Colonoscopy
I was very impressed with Dr. Cahill. The procedure started on time and and apparently went smoothly. Following the procedure Dr.Cahill came in and explained the findings. I found him to be both professional, and congenial. I strongly recommend Dr.Cahill as a gastroenterologist.

It was a great visit. I was able to make several decisions as a result of the visit. One of his recommendations was particularly helpful. I expect to be in up coming contact with the clinic in view of the fact that two tests have been ordered for the future.

It was different experience during a COVID pandemic. But I felt cared for by professionals throughout my time in the clinic. I had never met Dr. Cahill prior to my procedure. It would have been nice to have had a sort tele visit or him drop in while I was in prep rather than just before the procedure.

I've never had such a thorough and careful doctor as Dr. Cahill. He checked everything possible for my issues. Because of this, I feel less anxious about my medical issues. Dr. Cahill communicated with me three times by US mail over a 2 month period while i was completing the various scans and blood tests. I often referred back to his letters. He gaveme my treatment options, along with his recommendations. I would strongly recommend Dr. Cahill.

Dr. Cahill is a fine gastroenterologist. During a recent colonoscopy he located, removed and tattooed 2 precancerous polyps. I appreciated his careful instructions following the procedure for myself and relatives. He is an informative and knowledgable doctor and I highly recommend him.

I would highly recommend Dr. Cahill - he has a great bedside manner and I felt very comfortable with the procedure. I honestly thought having an endoscopy would be awful and it was anything but. He explained everything very clearly to both my husband and I.

I was treated by Dr. Cahill and other members of this practice while in the hospital for 3 months. Dr. Cahill was the GI I chose to continue seeing after I got home. He's been very easy to talk to, supportive, and with his advice and recommendations my Crohn's Disease is in remission.
