Patient Rating

Patients overwhelmingly praise Dr. Enniss for clear, detailed explanations, taking time to answer questions, and showing compassion and professionalism. Many comments note his competence, thorough counseling about treatment options, and that he listens carefully, which helped reduce anxiety for visits. A small number of reviewers, however, reported feeling rushed, dismissed, or having poor bedside manner, with one saying a long trip felt wasted when their concerns were not addressed.

Dr. Enniss counseled me about surgical options for my small bowel obstruction, in the event the gastro-grafin solution failed to clear it in the future. He believes the ilium was injured by radiation treatment of my prostate in [DATE REMOVED], causing an adhesion to the pelvis. He stated these adhesions can set up much like concrete and when attempting to reach this location can be difficult, causing even more scaring. Given my age (83) and possible outcomes from surgery we explored all the available treatment, and options. Dr. Enniss spent over 30 minutes with me, listening carefully, letting me know he heard my preferences and concerns, snd answered every question until I had no more. He is a kind, thoughtful professional and I would recommend him to anyone exploring solutions to health problems that involve surgery. He let me know he was available for any surgery I chose, and I have full confidence in his ability to produce the best outcome possible.

When he came in, he did a good job of explaining things, but he almost felt like he was in a hurry to get out and so, but other than that, he did really good on stuff

The assistant had a vibe about him that made the appointment not seem so intimidating anymore.the doctor explained everything I needed to know about the procedure but I think his approach could be improved. I personally don't mind being bombarded with the possibilities of complications so that I'm aware but I think it could be overwhelming to receive that much information in a short amount of time for some people. he really did do a great job with his explanations though and I appreciated BOTH gentlemen!!
