We launched the new Progressio site for their 75th anniversary in Spring 2015, it's a custom coded responsive theme on Drupal 7.
We brought all Progressio's content over from their old Drupal 6 site, and wrapped it in an on-brand redesign, we worked closely with their fundraising and comms teams to refine the calls to action and user journeys, and to showcase their great photos, blogs and other content and integrate their social channels.
