The staff and billing here stinks. U can never get through the phone lines to talk to someone. It takes more than 2 months to get an appointment. I was charged 6 months worth of bills, cause the billing lady was too lazy to pre authorize my visits with my insurance. So I ended up with 6 months worth of bills from my insurance company. I went there for over 6 months and no helpful treatment from DR Jimmy Tran. When I asked to see another specialist, they told me insurance would not cover it, I would have to pay cash.
