Patient Reviews
Dec 12, 2024
If your little one needs a ped GI, Dr. Haas is your guy! He is truly the best in every regard. His bedside manner is warm, inviting, caring, and genuine. His training and expertise is top notch and I always feel reassured that my son is in THE BEST hands. Dr. Haas communicates very well and provides clear next steps and follow up. He is responsive and extremely helpful when it comes to answering questions. My little guy has a complicated case and Dr. Haas steadily navigated us through many challenging situations. In case you can’t tell already, we love Dr. Haas and wholeheartedly recommend him.

What’s a board certification and why is it important that my provider has one?

A board certification represents a provider’s dedication to ongoing training in one or more specialties, including the completion of intensive exams.
