Daniel Ziskin grew up in a car-dependent sprawling suburb of Philadelphia. In 1993 he received a Ph.D. in physics from The Johns Hopkins University by studying clouds and their effect on climate. After his ultimate frisbee career peaked, he became involved as a transportation activist fighting the construction of a wasteful outer beltway around Washington, D.C. In 1998, Daniel moved to Boulder. He donated his car to eGo CarShare and joined the board around 2001.
