Easy to maintain
This site is run by a community collaboration, where lawyers, mostly volunteers, insure children receive quality healthcare. The organization is small, with everyone involved having fulltime jobs elsewhere. So keeping up the site must be simple and take as little time as possible away from the mission of the partnership.
Over the years, the group has produced a great deal of very useful information. These resources need to be distributed to several audiences, including people seeking help and other groups doing similar work elsewhere. This required many pages for such a small organization, so a theme that would handle those many pages was selected.
