I have used quite a few billing companies but none as good as this one. They are always on top of what needs to be done and there is no need to remind them. There are very few mistakes, and payment from the insurance companies is quick. They issue all bills in a timely manner, and are on top of keeping track of all outstanding bills. They even issue a weekly report if requested detailing what was done in regards to the bills that week. All in all they are by far the most reliable billing company I have used
