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.

Excellent care.
My wait time to see Dr. Guerra was a bit long. However, once I saw him he gave me excellent care and answered my questions and gave me feedback.

The Best!
For close to twenty years Dr. Guerra has been providing gastroenterology services for me. There has been colon cancer in my family history so I have been recommended to keep a more frequent schedule for colonoscopy examination. That being said, I have been seen at Dr. Guerra's office several times over the years. This last visit, like all previous visits, was professional and compassionate from check in to check out, from front desk assistant to the doctor himself. Dr. Guerra is committed to the best that medical technology has to offer. This commitment blends well with his knowledge and experience in his specialty. For these reasons, I feel Dr. Guerra is one of the best if not the best choice in the field of gastroenterology.

Caring and Professional
Dr. Guerra, Jr. has been my doctor for many years and every time I see him it is like sitting with a friend. He sits down and he looks at you when you talk and he listens. When I was scared he reassured me and my family everything would be ok. There have been times that I have needed to be seen immediately and his staff get it done. When you go in to see Dr. Guerra, you are not just a name or a number, you are an individual that is truly cared for. Recently I was in the hospital and my arms were all bruised up from all the pokes. The triage nurse looked at me and asked where she could place the blood pressure cuff because she did want to hurt me. I was taken back, because at my earlier appointment no one bothered to ask, they just took my blood pressure. The staff checks in on you before a procedure and then for 2 days after the procedure. Dr. Ernesto Guerra, Jr., is truly an angel among us. You can feel that he genuinely cares for his patients. His staff is also very caring

Best GI doctor I know!
Dr Guerra is an excellent, caring doctor! He listens to your concerns and then takes action right away by ordering labs, Ct scans, x-rays etc. Highly recommend him if you want a doctor that truly cares about your health. Doctors like him don’t come around easy.

Excellent Doctor and Experience
Dr. Guerra stands at the very top of all the Doctors I’ve ever seen for listening to me, explaining the necessary procedure, and then on the day of the procedure making sure I understood and was ready and comfortable with having the procedure that day. I never felt any worry or concern about my care and had total confidence in Dr. Guerra. I wish I had more Doctors like him.
