Urban Health Project (UHP) is a non-profit I've worked with since 2004. UHP is made up of first-year University of Cincinnati medical students who work for local non-profit health organizations in Cincinnati. Major focus areas for this site are posting summaries of members' internship experiences and recognizing sponsors. The site was developed extensively with CSS and ASP to allow for maximum flexibility for future updates.
