when you hire bernie, that is who you get. he doesn't send a stand-in, nor does he come for only a short time and an assistant does the majority of the work. bernie coordinates the whole event.
bernie is a professional dj. he is moving toward 25 years as a radio disc jockey - listen to him on the b 105.7 fm morning show. in fact, visit the radio website (be sure to come back).
really, you should listen to his radio show. it is a convenient way to do an initial audition for what you might want him to do for your special event. just remember, bernie does it all, not just soft rock.
