Dr Sun is amazing! She is personable and takes the time to answer all my questions and address my concerns no matter how silly or small they may seem. I’ve been going to Metro Dermatology for a few years now and have had a pleasant experience every time. Dr Sun knows her stuff and you will definitely feel better and see results under her care. Thank you Dr Sun!!!
