Dr. Brenner has treated me since 2010 when I first suffered from UC. She listens, returns your calls and is easy to converse with regarding your difficulties! I do believe that she sincerely cares about her patients and their health!

I had a concern on a scan I had and Dr. Rufner spent about half an hour with me discussing the report. He did a drawing in explanation of what the scan was showing, which made me feel very comfortable. He was familiar with the diagnosis and did a great job explaining it. We continued the conversation about other questions I had and it was a relief to have his consult. He is a very thoughtful Dr. with a great bedside manner.

Dr. Sieja was great! This was my initial visit and he took time to ask me about my personal and family history. He asked me questions about how I was doing and provided me the opportunity to discuss any questions or concerns that I had. Completely recommend.
