We've been on the other side of the window:

We've worked in physician's offices...

Fought with insurance companies...

Scheduled surgeries and appointments (then jumped through hoops to get them authorized!)...

We've managed physician's offices and worked for IPA groups.

And if this tells you something about our experience: 

We filed our first insurance claims BY HAND with a peg board and ledger!  

Things sure have changed since then....
