“My husband and I have a small practice but we were looking for a medical billing company to consult us. We originally started with a local company with some satisfaction. However, our biggest problem was that they wanted us to change our existing EMR to software that they worked with. Quest National Services worked with our existing software so that we didn’t have to make expensive changes to our infrastructure. That saved us a lot of time and headache. I would definitely say that was one of the main reasons for why we switched and why we continue to work with Quest. As a small practice, they helped us without draining our resources.”
