They are always there to answer the phone when you need them. It says a lot about a company when the owner is the one you are speaking to when you call. I love that they don't outsource their phones to other countries - when I call them I get them directly at their office.
Roxana and Andy are friendly, personable, and most of all great at what they do. I plan on being a long-time client of Millennium Medical Billing.
Pros: Very personal, yet still professional.
