    I had a very satisfying video consultation with Dr. Sunny Lo.

    Dr. Lo was very punctual and called me at the exact appointment time. He was very patient and showed a great deal of care. Unlike some other doctors who rushes to end the consultation, Dr. Lo spent more than 30 minutes discussing my case. After the consultation, I emailed him few times with additional questions and he all responded within an hour. I am so glad that I have found a truly trustworthy Gastroenterologist. Highly recommend this doctor!

    overall Dr Sunny is a kind, super thoughtful dr. He will explains questions you have. However, I had to wait long time for follow up appointment and there seems to be some miscommunication between the front desk and the doctor's schedule because he took long to help me every time we have an appointment. Let say appointment scheduled on 1pm; he will not call or handle you until 1.45pm, which is sometimes frustrating to wait too long.

    I am so grateful to have found Dr. Lo! GI problems can be scary but he and his staff immediately put me at ease. The front office staff greeted me with a huge smile and didn't hesitate to help me request 10-year-old GI records from another state. His nurse spent ample time really understanding my symptoms before I ever saw Dr. Lo and then Dr. Lo helped put my mind at rest during our initial consultation.
