The Marathon Jam is a once-a-year event in multiple states and multiple countries that raises money for The Fisher House (like the Ronald McDonald house for injured soldiers’ families). They needed a professional site that encouraged donations and informed visitors about events.
I volunteered to build and manage this site from a WordPress theme. It’s not a fancy site, but it’s all the Marathon Jam needs: obvious donate buttons on every page plus a calendar and images that say what they do front and center. To me, this site is a good example of efficiency. It does everything they need without being overwhelming.
