The Contractors Association of Truckee Tahoe is a non-profit trade organization with 300-plus members. I built their previous website in 2010 using Drupal 6. As their organization evolved over the years, so have the needs of their website.
CATT's new website has a comprehensive member listing system with a strong focus on search engine optimization, an advertising module with Google Analytics tracking, responsive design (so the website is easily viewable on all mobile devices), and an interactive events calendar. With enhanced listings and on-site advertising, the site is now a revenue-generator for the organization.
