"Dr. Sun provided exceptional care. She not only addressed my medical concern but also demonstrated empathy by patiently listening to my concerns and questions. Her staff was wonderful too! Thank you everyone!"
"Awesome team, made it all look easy!"
"When we recently met to discuss a GI condition I’m experiencing, Dr. Sun listened to me attentively, asked important questions, and set up a plan to begin to deal with the situation. She explained the reason behind each recommendation as well as possible side effects. I was referred for some outpatient tests and received detailed feedback on the results promptly through her nurse. While very knowledgeable, Dr. Sun is still humble and personable. Based on my interactions so far, I highly recommend her."
"Nurses explained everything clearly. Dr Sun always cheerful and ready to answer questions you have."
"I picked Doctor Sun because of her good reviews and she didn’t disappoint. Very professional, she came to talk to me before and after the procedure and was very nice. I can only say the best about her and her staff."
"We're caught in Verizon outage. Can't get calls in or out."
"Dr Sun and staff did a wonderful job. Thank You!! Was comfortable being there!"
"Dr. Sun was great. Knowledgeable, interested in what I had to say."
"Very professional and friendly staff. Dr. Sun had reviewed my previous colonoscopy and was confident if there were polyps again she would remove them. After the procedure she shared with me the results . Everything went smoothly and I felt great."
"I am not good at English, but I was able to speak with an interpreter. The doctor listened to me very carefully and answered all my questions. I was given the advice I needed."
"Dr. Sun & her team are awesome. Most of the front staff is nice too. Except for one woman at the front with glasses. On numerous occasions, she has been quite rude every time I've been there. Please note, I understand how most front office staff have to deal with a lot of patients & are doing a lot all at once or maybe short staffed everywhere, but compassion to each patient IS necessary. Please find a better way to auto answer your phones when you're busy. That's totally understandable...but to make curt remarks about how people are late when you KNOW your system is glitch is NOT necessary. Treat each patient like a human being since WE are the patients with the physical problem while we are paying for the services of the great doctors but not to be treated like cattle or little kids. Check your attitude down a notch since most people are already not feeling well to begin with. Thank you. Otherwise, great, clean efficient office with other compassionate staff on hand once you slay the dragon at the front."
"I truly appreciate and really felt cared for! Dr. Sun is a great doctor. I Am grateful to have her taken care of me. And her Nurse Sue is fabulous, and so is the whole office!"

"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!"

"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 had Dr. Sun 2 years ago, who did my colonoscopy, who was so comforting explaining the result of the test, then this appointment I had with her last week 1/20/2021, I have to pray prior to the visit, that Dr. Sun will be the doctor im gonna see, and good enough she is the one who attended to me , who is very supportive especially with my medical issues & ordered tests but reassuring possible results, which 1 test is negative & the other test due in a year 1/2022 thank you very much for your good service care."
"Dr. Sun is highly intelligent, concerned with one's condition and care, professional and pleasant. She has been my GI for ten years as well as my wife's and we are completely satisfied with the level of care received."
"Great very friendly Drs. I cant say I enjoyed my colonoscopy, but they were very understanding and tried to make it as comfortable as possible."
"Very kind, patient, caring and thorough doctor. Really listens and takes her time with you. Explains everything very clearly. I highly recommend Dr. Sun."
"It can take a while to get an appointment with her, but it’s worth the wait. She is kind, very detailed, and seems to ask all the right questions. 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."
"Dr. Sun listened to what I had to say. She was compassionate and I felt very comfortable with her."
"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."
"Terrific place to go if you have tummy troubles. Staff is very friendly and helpful. My doctor is wonderful she is very caring and thorough. She actually listens to you and never makes you feel rushed. She explains everything perfectly. I am so happy I have found Dr Sun"
