While listening to WOR New York's "Rambling with Gambling" one day in 1979 Aaron's father suggested radio would be a good career, and at 12-years-old a budding broadcast journalist was born. It was probably the first time Aaron willingly heeded his father's advice and he's glad he did. His interest in radio was further kindled by programs like CBS radio's "Mystery Theater" starring Fred Gwynne (better known as Herman Munster) and late night interview/call-in programs hosted by "nobodies" Larry King and Sally Jesse Raphael.

Aaron's first professional job after many years working for free - known in the business as "interning" - was with WLLH AM in Lowell, Massachusetts, where he got to chase ambulances, report live from polling places and any number of burning buildings, and attend the stupendous Lowell Folk Festival for free. From there he moved on to public radio stations in Amherst and Boston, Massachusetts, and Denver, Colorado. He covered the Columbine High School shooting, and for NPR the wildfires in Los Alamos, NM, in the spring of 2000. Also on behalf of NPR, Aaron had the pleasure of the LAPD's hospitality during the Democratic National Convention in August, 2000, where he reported from the protesters' point of view. Though he lost a good deal of weight marching in the streets, he was most distraught not to have been gassed or shot at even once the entire week. Aaron most recently worked as an editor, reporter and host for PRI's daily business program, "Marketplace", before joining the staff of The World in the summer of 2002.
