    From the receptionists to *Dr. Lee, the visits to the office has been excellent.
    Dr. Lee was very friendly, professional, and made me feel very confident in her abilities and in the information she provided.
    Dr. Monica Lee seemed a bit distracted and had to excuse herself form the consult a couple of times. She apologized because of a situation from one of the other patients in recovery, post-op.
    It is my first time encounter, have no comment yet
    I think she doing a good job.
