"Dr. Arndt was very kind, patient and professional. His staff nurse Linda was very nice. I have very high anxiety and they both gave me a peace and a comfort which is uncommon for me when it comes to Doctor visits. Before leaving, both invited me to call any time with questions or concerns."

"Saved my life in 2004 insisting "something terribly wrong " with this woman. I went ER with abdominal pain. Diagnosed with rare cancer. Have seen him since then with other gastro issues. Very patient, always listens, very knowledgeable."

"having had G.I. problems my entire life, I have had occasion to work with many Gastroenterologists. I have seen both good and bad. Dr. Patricia Sun is one of the best. Her caring attitude, and true empathy for her patients "shine" through. Having these qualities added to a knowledgeable well educated professional who is very adept at her chosen field makes for a genuine "Home Run" I am glad that her relative youth (relative to me!) ensures that she will be able to continue to care for me for a long time. This has been my problem in the past. I have outlasted my previous Doctors which has been disheartening since the continuity of care lapsed. Dr. Sun is not only well versed in Gastroenterology, but she is able to incorporate her Internal Medicine background to care for the ENTIRE patient, not just a small part. I have no reservations recommending Dr. Sun for not only her professional skills but her charming and truly caring personality. Don't forget that one of the most important parts of a Dr's office is the support staff. This office is second to none. This is not hyperbole. From the front desk with Erin and Donna to Margarita, the office manager, to Natasha and Tatyana in the Nursing area. They "ROCK". I could go on forever, but i don't want to swell any more heads. Don't go anywhere else. This practice is it!!"

"Dr Treanor and his staff along with others at Illinois Gastro treated me with respect. I arrived 15 mins early and when I walked into the waiting room some one took me to my room for the appointment with Dr Treanor."

"He was prompt and spent his time examining my father, talking to him and developed a plan of care. My father has been seeing him for years now, since he was the only Dr to treat his condition correctly. He was hospitalized time and time again for abdominal pain that every other doctor had no explanation for as his tests all came out unremarkable. He was the only doctor to diagnose him correctly with Mediterranean fever and prescribe the needed treatment (after years of testing and other drs)."
