  • Dr. Liu has been my Primary Physician for many years. She is experienced, listens to me, and has a great attitude. During the last two years I have had a significant number of medical issues. She has explained, organized, interpreted and been very helpful to me and my family. She is by far one of the most humanistic doctors I have ever had.

  • personalized primary care
    Dr. Liu is fabulous! She is one of a kind and takes great care of my husband and me, especially Tom who is battling Parkinson disease. There is never a time when we are waiting for test results that we have to call the office; Dr. Liu calls us to follow-up and sometimes just to see how we are doing. She is priceless.
