John Earl Clark holds a Master's degree in Human Computer Interaction from Georgia Tech and an undergraduate degree in Music Engineering from Georgia State University. He and his co-author, Bryan P. Johnson, worked together at MindSpring and, later, EarthLink; starting out in Technical Support and Documentation before moving into application development and, finally, the management of a small development team. After leaving EarthLink in 2002, John began working independently as a consultant and a programmer, before starting Twelve Foot Guru, LLC. with Bryan in 2005.
When he is not buried in code, John spends his time woodworking, playing guitar, and brewing his own beer.
