She remained calm, professional, and focused, ensuring the procedure was completed safely and effectively.

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.

Dr Sun and staff did a wonderful job. Thank You!! Was comfortable being there!
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.
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.
