"Dr. Sun, the anesthesiologist, and the nurses & staff here are exceptional! I was there for my first ever colonoscopy - nervous, as one might imagine - and everyone was absolutely courteous, pleasant, thorough, and professional. While I am not exactly 'looking forward' to my next visit, I know that I will be in good and capable hands with Dr. Sun and his team of awesome folks!"

"I just had my first ever visit to a Gastroenterologist after receiving a positive diagnosis to a Cologuard test. Dr Sun appeared to be very professional, and explained what various results could mean. His office staff was also very courteous and efficient, especially the person who scheduled my Colonoscopy."

"I went to see Dr. Sunil Joseph for the first time after Dr. Asghar Syed sent me to him with my lab report for the Colonoscopy. I found him as a kind, humble, and humorous gentleman man who truly listens to his patients. His staff was very helpful, polite, warm, and quick responders; assigned me to a recent date for the procedure due to my condition of having rapid weight loss, arthritis and very low in iron and hemoglobin. I highly recommend becoming his patient if someone has serious concerns about Gastrointestinal issues"

"Dr. Sun was very easy going and took his time with explaining my colonoscopy results. He really explained everything that was going on and gave me two of his best treatment options which he ultimately left for me to decide. He was very welcoming and you can see how all of his experience has shaped him by just having one conversation with him"

"This was a pleasant experience here. This was my first time with Dr. Sun but he made me feel very comfortable. As usual for a colonoscopy, the worst part was the prep but after that the Elgin group made me very comfortable."

"I went in for a colonoscopy and an endoscopy I was so scared and Doctor Sun was so great in helping and doing both procedures I hope I don't need the gastro group again but if I do Dr.Sun is my first call"

"Today I had my colonoscopy with Dr. Sun. I chose her because my health insurance has her rated as a Premium Quality Physician. Dr. Sun has an excellent bedside manner. I was extremely nervous and terrified today about the having the procedure because my BFF in Detroit passed away from colon cancer just two weeks ago. I explained this to Dr Sun then she unexpectedly held my hand and assured me she was going to take good care of me. This sincere and very kind gesture made me feel comfortable and at ease because I was a bundle of nerves. Her nurse Mary Beth put a cold compress on my forehead to further calm me down which worked. After the procedure was finished Dr. Sun came back to me and gave me my results she held my hand again. Not only is Dr Sun a very highly skilled physician but she is also very caring. I highly recommend her to anyone who is thinking about having a colonoscopy. I also must mention Marie also on her staff was very professional and courteous when I called to set up the appointment and she gave detailed information on preparing for the procedure. Marie did not mind that I called her back several times to make sure I was doing everything correctly to prepare for the procedure."
