At Duo we use our enterprise-level experience to push Drupal’s content management system (CMS) and its modules, in order to raise the significance of the role web interaction plays in our client’s organization, and to assist our clients in creating a remarkable, engaging user experience.
Drupal’s flexible and reliable web development is used on numerous high-profile websites such as the United Nations, Recovery.gov, the White House, Warner Brothers Records, the Discovery Channel, Forbes, Yahoo, and The New York Observer.
Drupal is a free, open-source web content management system written in the PHP programming language. However, the simplicity and sophistication of Drupal allows system administrators to customize the content and display of their websites without any programming knowledge or skill. If you do have a background in programming, Drupal’s modular theming system allows custom-written themes to be added without disturbing the core CMS system.
Drupal’s wealth of available modules add functionality to the system, and while many are built and maintained by the core Drupal developers, other are contributed by the larger, interactive Drupal user community.
Duo’s team utilizes Drupal to build flourishing websites and content management systems that can handle high volumes of data efficiently. We integrate these capabilities and user-friendly features with other applications and web services to build our clients unique, custom solutions using “best fit” technologies.
Drupal is a mature platform, now moving into its second decade. It has enterprise-level backing through Acquia, and Acquia has designated Duo Consulting as one of its Enterprise Select Partners.

When you work with Duo, you're working with the best.
Part of the ethos of the open-source community, and the Drupal community in particular, is to contribute back to the community as you can. Duo does that in several ways:

Why are we doing this? Because Duo is committed to the Drupal platform, and we want to give back.
