David Noonan began his career with Wizards of the Coast in 1998. He contributed to the design of the three core books for the third edition of Dungeons & Dragons. For the new Dungeon Master's Guide, he developed the treasure tables, based on guidance from Monte Cook, and worked on the non-player characters that appear in the book's second chapter. Noonan also contributed some prestige classes to Sword and Fist, as well as designing a large part of Song and Silence, and spent five months on editing and design work for the third edition Manual of the Planes. Noonan, Andy Collins, Mike Mearls, and Jesse Decker were part of Rob Heinsoo's "Flywheel" design team for the fourth edition of Dungeons & Dragons, and did the final concept work from May 2006 to September 2006, before the first books for the edition were written and playtested. Noonan was one of the eVoices of Wizards on the D&D podcast. On December 2, 2008, Noonan was laid off from his employment with Wizards of the Coast.
