Ask someone how they know Dennis W. Green and you might get any one of the following: Writer, DJ, actor, swimmer, tech geek, husband, or dad. So it's little wonder his favorite quote comes from Robert Heinlein: Specialization is for insects. A popular radio personality in his native Iowa, Dennis has also worked on the stage, TV, and independent film. As a DJ, his adventures were covered by newspapers from Anchorage to Los Angeles. By day, he is the general manager of Iowa's only jazz radio station, KCCK-FM. And if it's 5:30 am, you can probably find him in the pool, working out with the Milky Way Masters swim club.
