I have worked with McKenzie Paul & Associates while working at three separate companies. I first worked with them while employed by a newspaper in Mesa, AZ. They were able to collect most accounts we sent to them. We used this agency to collect our largest and most difficult accounts, and they did not disappoint. I then used the same agency when working in Carson City, NV. We did not have very many accounts that were difficult, but MPA collected what was placed with them. I am now using them while working with am employer in Scottsdale, AZ. The accounts we send are very difficult and they are still able to recover most of the amounts I believed to be a total loss. I recommend MPA to anyone who has difficult accounts that need be recovered!
