I'd like to extend tremendous thanks to Brian for shouldering the burden of the rewrite for this second edition yet keeping me as co-author. Thanks to Donald Lobo and Dave Greenberg for founding CiviCRM and seeing it through its first 10 years. And thanks to Tim Otten, Coleman Watts, and Josh Gowans for taking over as the next generation of CiviCRM core team leaders as we begin 2016—you'll do a great job coordinating this amazing open source community.

Brian P. Shaughnessy is the owner and principal of Lighthouse Consulting & Design, a web development firm specializing in CiviCRM implementations for Joomla!, Drupal, and WordPress. Brian previously worked with a communication firm serving not-for-profit professional, trade, and charitable organizations for over 10 years. After starting his own business, he channeled that experience into effective implementations of CiviCRM for not-for-profits and government institutions. He has worked with organizations around the world, helping them to achieve greater efficiencies and expand functionality through CiviCRM.

Brian is very active in the CiviCRM community, regularly contributing code to the core software, speaking at CiviCon events, and helping to lead a local user group in the Albany, NY area. In the past he has worked with the core development team to provide end-user training and maintains a strong working relationship with the project leaders.

He extends his appreciation to the core team—particularly the founders, Dave and Lobo—as well as the many other core team developers and community developers around the world who have helped make CiviCRM a powerful tool in the hands of not-for-profits, community organizations, and government institutions.
