Reception staff was friendly and polite. I was seen shortly after my arrival by Dr. Sieja who examined me further and then discussed with me his plan for treatment. Dr. Sieja was very cordial and professional and displayed expertise in his field of medicine. Would highly recommend him to anyone experiencing gastroenterology issues.

It's so refreshing to see a doctor that will take the time to explain results, diagnosis, and treatment with you and who will also take the time to answer your questions completely and make sure you understand. Dr. Rufner is very knowledgable and is able to relay information to his patients in a manner that makes sense to them. He cares about his patients and their treatment/recovery and I trust him completely. Would highly recommend him!

Dr Rufner was so easy to talk to and gave me so much more information than any other gastroenterologist I’d ever been to. I felt like he was really trying to get to know my history and help me as much as possible.

Dr. Rufner is an excellent gastroenterologist. He takes the time to talk to his patients, provides thorough explanations, and works to find a solution to a patient's specific condition. He is the first GI specialist/pcp to think outside the box regarding IBS and suggest other treatments besides the FODMAP diet or anti-depressants. Reducing bile acids through medication has helped reduce my symptoms. Very appreciative of Dr. Rufner's experience and expertise. Decent amount of turn over with his staff which has made phone f/up and scheduling appts a bit of a challenge, but they are aware.

Dr. Rufner really takes the time to listen, and explain things and is interested in managing chronic diseases, not just “labeling it” and handing people off to an NP or PA. Very approachable and interested MD. After all of my appointments, I have walked away feeling informed and like I have the tools to manage.
