“Dr Wu has been seeing me every 4 months for ear cleaning over the last year. She has completed 2 surgeries on me. She is gentle and answers all my questions (which are many). Over the years I have suffered with terrible ear infections and other doctors have not solved the problem. She came up with a plan and for the first time in years I am infection free! I highly recommend Dr Wu! ”
