"Actually, I just found out that it was not Dr. Sun''s fault that I did not get my results, they were in mail right away. So, then not only did I get a call from the nurse, who shared the results over the phone, but also from administrative office, asking how they can remediate the situation. To me that is good customer service. So, I changed my review to what I feel they deserve and I am going to continue my follow up visits with this doctor. Dr. Sun is awful. I got two procedures done two months ago, no communication about biopsy results. No communication whatsoever. Just sent the bill, no care, no concern, I would have given them 0 stars if it was possible. When I had to take time off work to call them, put me on hold for extended amount of time, and did not give me any results."

This office is a completely different experience! I haven’t had to seek my own pre authorizations, I haven’t had to advocate for my infusion renewal, and perhaps most amazingly, they were able to help get me approved for an infusion co pay plan that I’ve been trying to get into since 2018.

"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!!"
"I was referred to Dr. Sunil by primary doctor for pain that I have been having on and off for some time now and this was I first visit. I was very impressed with the time and questions Dr. Sunil had to try and figure out what to do next. Extremely nice and very professional ."

She takes her time assuring you understand your particular situation. She doesn’t order a ton of tests like some doctors. If necessary, will do telehealth."

"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"
"This practice is very knowledgeable, professional as well as, concerned with the well being of its patients. I highly recommend this practice as well as Dr. Sun. I have been seeing him for many many years."
"Up on coming to my visit Dr Sun was nice and his aids i talk to him about my problems he was concern about them and scheduled a appointment for surgery right away."
"Dr Sun is extremely bright and a fantastic doctor!"
"Not only is Dr Sun an excellent physician, she also communicates very well leaving no questions unanswered. Great concern for her patients!. Both my husband and I completely recommend Dr Sun!"
"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."
"All was very positive and Dr. Sun takes her time."
"Very happy with Dr. Sun. She was a great listener, and very patient while listening to me describe my symptoms - not condescending at all. Knowledgeable and encouraging."
