Don has worked at OIRA nearly from its inception. He joined OIRA in 1981 and, over the next several years served as a Desk Officer and then as Deputy Branch Chief for the Commerce and Lands Branch, covering a variety of agencies including DOT, EPA, DOI, USDA, SBA, and DOC. He worked closely with OIRA's Administrators and Deputy Administrators during the Reagan, Bush, and Clinton Administrations on broad regulatory and information issues, including the many controversies surrounding regulatory review. Don became OIRA's Deputy Administrator in 1996, serving as Acting Administrator for 18 months in 1998 and 1999 and during the transition between the Clinton and Bush Administrations. He is now serving as Deputy Administrator and Acting Administrator.
Prior to joining OMB, Don worked at the National Transportation Safety Board. Before that, in what turned out to be a singularly ill-timed career move, he was a professor at a university in Iran, setting up an American Studies program in 1977 and 1978. Don has a BA from Harvard and a Ph.D. from the University of Pennsylvania. He lives in Alexandria with his wife and son; his two older children and spouses live in Cambridge, Massachusetts and Norman, Oklahoma.
