She is very easy to talk to and answers all questions you may have and more importantly always has a plan of action. She has helped me so much in so many ways.

"I’ve had many gastroenterologists that I have seen since I was 6 years old for my medical conditions. I’ve encountered many ER visits for my condition as well. I unfortunately haven’t had the best of luck with doctors. So seeing someone new makes me nervous. I always research who I end up seeing because I’ve encountered a lot of doctors who don’t listen. Who don’t believe me. Who brush my condition off because I’m young and I am not a forceful person. But dealing with a condition for 25 years, you learn a thing or two about it. I’ve had alot of guy gastroenterologists assigned to me after emergency visits that seem to not work out the best. I give the benefit of the doubt but end up having issues that never resolve. Meeting Dr. Sun was life changing. She’s incredibly kind. She listened. I started tearing up talking to her because it’s been so long since I found a doctor that heard me. That didn’t talk over me. Didn’t try to in-put random things that didn’t pertain to me. She listened! I struggle eating food to the point food gets stuck daily. And to finally find someone who not only hears everything I have to say, but she cares! You can feel just how much she cares about her patients in the way she talks, it’s everything. I will need to have a procedure done once elective surgeries are able to be performed due covid cases being too high right now. But I feel confident that when I have it done, she is the best person to do so! Highly recommend her!"

"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!!"

"Made the transition from my old GI practice to new seamless and painless! Dr. Sun was highly recommended in a private group on social media and each review was true! She is tremendously kind, patient, and genuinely invested in her patients. Her office staff is just as amazing!! I loved my old doctor but had no support from the staff. 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. I cannot say enough about Dr. Sun and her practice and I’ve only been a patient since December 2020. I am so grateful to be with this doctor and this practice!"

"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."
