Patient Reviews
Jan 10, 2026
My husband and I have seen Dr. Sun for over 3 years. I felt he was very knowledgeable. Unfortunately my opinion of him has changed. I still think he is very knowledgeable but unfortunately I’m not sure we will be returning for follow up visits. My husband saw him yesterday with an 8:45 appointment. At 10:15 he had still not seen the doctor. Today I went for my follow up appointment after a colonoscopy and endoscopy. I was diagnosed with Barrett’s Esophagus, a precancerous condition. I went in with questions but prior to answering all of them he closed up his laptop, put it under his arm and started to walk out stating his appointment slots are 15 minute slots. I was devastated. He just said I had a precancerous condition but left me sitting with questions. Perhaps I would have had more time to ask questions had I not had to wait for him to dictate into his laptop DURING my visit instead of after. He did apologize but said I went over my time and sometimes he double books.
