Dr DeCarlo is an excellent doctor. He has removed 2 kidney stone from my husband...very quickly both times. He is an great choice for a urologist should you need one...hopefully not, but a great choice.

You get a sense that this doctor had it together. He had excellent bedside manner and shows a genuine concern for your health and doing the right thing.

Dr. DeCarlo has been recently seeing me for persistent UTI's, though I have been a patient since the 1990's. At this recent follow-up visit he was very thorough, going over test results and recommendations. He answered all my questions to my satisfaction, and took all the time necessary to do so, yet without wasting either my time or his. He makes excellent eye contact, his manner is relaxed yet professional with dry humor when appropriate. A word about his group practice, they are part of the UT Health System, yet use the Christus patient portal for online patient communication. Additionally, they charge both an office and a facility fee.
