I had an excellent experience with Center for Digestive Health and Dr. Partha Nandi. Dr. Nandi took the time to truly listen, explained everything thoroughly, and answered my questions with patience and confidence. I never felt rushed. You can tell he genuinely cares about his patients and wants them to feel informed and comfortable. Our discussion left me feeling hopeful and confident in my care plan. I’m very grateful for the experience and highly recommend him and his team.

From the moment I walked in the door, everyone was so pleasant & friendly. I knew again that I was in the right place for testing & future treatments. Dr. Richard Willie & his procedure staff is very kind & pleasant as well. I would highly recommend him for any gastrointestinal needs anyone has! Another event end of year 2025 that sent me to the ER & needed a follow up with Dr Wille. I again highly recommend Dr Wille. He cares, he's patient & thorough. I cannot express enough how wonderful Reneshia (nurse in scheduling) was. This event was extremely difficult for me & she calmed & reassured me all would be well. Thank you for having her in your practice!

A very professional group of people. I honestly believe that at their facility patients do come first.

Blood Draw was quick & efficient once we got to it, so that's where the 5 Stars come from. However, I had to read through a 17 page Research Study document (which could have been sent in advance), then sign the paperwork in what appeared to be an examination room in one building, and then, strangely, had to walk across the parking lot drive to a second building for the blood draw....? Seemed like all could have been done in one building or the other. (The second building had a regular waiting room like any other doctor's office.)

Friendly and compassionate care

Everyone here is incredibly kind and caring. I had some anxiety when I was preparing for my procedure, but it was done and over with before I had time to think about it. Dr. Donat is excellent, and takes time to explain everything.

I’ve had several endoscopic exams with Dr Quallich and colonoscopies with Dr Donat here. I’m always pleased with their treatment and feel like they genuinely do their best to consider my health and safety. Also the exams are painless and I’m pretty alert after waking up with their exclusive use of propofol for anesthesia. Thanks again!

Dr. Abadir was very nice and thorough. He cares about his patients and will do what is necessary to resolve your health issues. We have been to the Romeo plank office which was very clean.The only thing is when you are greeted they are nice and thorough but need to smile. 🙂

Saw Dr Bologne on a referral for 2nd opinion. Extremely pleased with that visit. He was 100% prepared and obviously read all the notes my doctor had provided. His diagnosis was much more thorough and thought-through than the 1st diagnosis I had received. Very glad I saw this practice and provider for a second opinion. Highly recommend.

Center for Digestive Health is a perfect place to go if you have any type of digestive issue. They make you feel very comfortable talking about any issue you may be experiencing and they ask all the appropriate questions all the while putting you at ease. When I called I was worried about something and they worked to get me right in. I saw the PA Noelle and she is just wonderful. Everyone at the desk and beyond are very welcoming and helpful. Dr. Weber has been my doctor there for years and I trust him explicitly. His assistant Debbie always helps me out and listens to me and is always very kind. The office is warm, clean and inviting. There are a few locations and so that makes it very nice. All in all I’m very impressed with this group of Doctors, Nurses and Assistants.

Kind and caring people work here!

I Really feel a deep sense of peace and trust in Dr Richard Willie. He knows first of all how to interact with his patients, listens carefully to them, and makes them feel important. Have been going to him at least 15 years, if not more. He is an astute observer, a fine doctor with honed in skills of lab interpretation, biopsy results, and well experienced in advising what’s best for the patients outcome. I couldn’t be in better hand with Dr Wille. I’m very fortunate to have him in my corner as a doctor who has both the training and wisdom to give me the best care now and for the future!
Wanda W.
Top notch service for out patient testing!
Bernie W.
Dr. Bologna reviewed my medical history and discussed my current situation. His care, compassion and willingness to do lab tests before any invasive procedures was refreshing. I have complete confidence in his ability to address my current issue.
Patricia H.
Everyone is kind, professional and competent. Very little wait time and good communication prior and after procedure. Dr Willie is wonderful!
