Michael Kostroff - Actor, Writer, Speaker

Michael Kostroff is an established working stage and television actor, best known for his five seasons on HBO’s The Wire and a long list of TV appearances, including recurring roles on The Blacklist, The Deuce, The Good Wife and Law & Order:SVU. He toured nationally with The Producers, understudying the lead role of Max Bialystock, and with Les Misérables, as the comically evil Thénardier, a role he later reprised for the reimagined 25th anniversary production. He’s also performed at some of the nation’s most respected regional theatres.

The author of three books—Letters from Backstage, Audition Psych 101, and Answers from “The Working Actor”—Kostroff also served as advice columnist for the actors’ publication, Backstage from 2006-2013, fielding questions from actors on a wide variety of subjects. His popular Audition Psych. 101 workshop, which addresses the mental part of the audition process, has been presented all over the country, with actors claiming tremendous improvements in their ability to conquer their audition nerves and anxieties. He continues to work as an actor, director, writer, instructor, and audition coach. www.auditionpsych101.com / www.michaelkostroff.com
