Let's help our guy Mark out!

Hi friends, our good friend Mark Peterson is getting hosed by the American medical system. He needs some help paying medical bills that we thought were covered but are not. I know he's always been there for me and I'm sure he's been there for you, so let's help him now that he needs it. You know Mark wouldn't go out and ask for financial help, so I'm doing it for him. Anything you can do would help out a ton.
