What Our Patients Are Saying

I’ve been a patient of Dr. Weber for almost a decade. My husband for more than & it was he who recommended Dr. Weber. He’s knowledgeable & well experienced in his field. Plus he’s an all around kind & nice guy. And you’d like how the office & tech staff are trained to run the operation of this practice. Efficient, patient and helpful! I’d feel very comfortable recommending this practice.

I had a great time. Everyone was very friendly and professional. One nurse said I had nice eyes, which really helped my self esteem. Dr. Willie was fantastic. His concern about having magenta ink for the printer really shows what a caring man he is. The pictures turned out great. I framed them and hung them up on my wall at home. But, seriously the experience was pleasant. Thank you to everyone involved.

Terry M.

Lord knows having a colonoscopy is zero fun. The prep nearly did me in. But after arriving at suite 270 every single person was pleasant and efficient. The attention to cleanliness in the office is very apparent and appreciated. Every employee introduced themselves by name, apologized for an IV that took two tries and made sure I was as comfortable as can be before I was ready to leave. However, I’m going to enjoy every minute of the five years before I need to return!

Marie C.

I have been here several times and have always been treated great. The receptionist are so kind and the nurses are wonderful so is the anesthesia person are so kind and answers any concerns you might have. My Dr Bologna is awesome. This is the place to go if you need endoscopy or colonoscopy. Thank all the staff for being so kind

Colorectal Cancer: Survival Rates of Early Detection

March is Colorectal Cancer Awareness Month, and the Center for Digestive Health is raising awareness about the importance of colorectal health. Colorectal Cancer is the third most common cancer in the US, with over 150,000 people expected to be diagnosed in 2023. However, with proper screening beginning at age 45, it is one of the most curable forms of cancer. Early detection and treatment remain critical to survivability, with early detection due to screening reducing the incidence of Colorectal Cancer by 89% and carrying a 91% survivability rate. Despite this, too many Americans are not following recommended health and wellness regimens regarding their colorectal health.
