    I really like Dr Sun - she's very thorough and reviewed all the notes from my previous doctor. But that clinic's too busy!

    The overall scheduling notion for care providers allows them too little time to listen to patients' concerns and answer questions patiently, and as their knowledge clearly qualifies them to do.

    Dr Sun was most professional, and verified what were concerning test results and contacted colleagues directly when an urgent referral was needed. Very conscientious

    I appreciate the explanations I received about my eyes. I always have my eyes checked every year so I was concerned about why I had not been told I had a problem. I accept the explanation I received. I currently live 50 miles away but I was determined to keep the appointment to check my eyes
