I have a doctor that I have being seeing since I was 16 years old and I absolutely love her! However the billing practices are absoultely shameful. I received a bill for under 30 dollars for a visit last November I called to ask if I could pay it when I came In for a appt in less then 20 days I was told that would be fine and today I received a letter that I needed to find another doctor because my bill was not paid! What? So 21 years and two kids with the office means nothing because of a bill for under 30 dollars that I was told it was okay to pay at my appt In a couple weeks? I watched a friend die this year ravaged by ovarian cancer so this is absolutely deplorable to me. I have let a message with the billing department so we will see if we can fix this mess if not I guess I will find another doctor after 21 years and thousands of dollars spent at this office.
