I had just moved to Redmond and visited Dr Chang's office for a regular bi-annual cleaning appointment. During the initial chit chat they figured I was new to the place and just joined Microsoft (big insurance cover!). At the time of appointment a helper took me in and while I asked for the doctor I was told that the doctor (Dr Chang) does not take cleaning work herself and that is "regular practice" in the state of WA! The dentist didn't even show her face during the entire visit while the entire procedure done by her helper. One month later I was landed with a $100 bill for co-payment for some treatment Dr Chang was claiming I had gotten done. Also they were claiming I had gotten a full mouth x-ray done which thankfully got covered by the excellent insurance that Microsoft provides. When I called the clinic for an explaination of the service as I had never got it done - they refused to answer any questions saying the hygenists (helpers) decision was final. The doctor refused to talk and when I ensued the receptionist threatened to put the bill on my credit record and banged the phone on me. I ended up footing the bill to protect my credit.
BEWARE!! Dr Chang does not care about her patients and is only after their wallet!!
