Dear Evan Hansen, which pairs the three time Tony Award nominated director Michael Greif (Rent, Next to Normal, Grey Gardens) with the Tony-nominated composing team of Benj Pasek and Justin Paul (A Christmas Story, Dogfight, NBC's "SMASH") and award-winning playwright Steven Levenson (Showtime's "Masters of Sex") officially opened at Broadway's Music Box Theatre on Sunday, December 4, 2016.

A letter that was never meant to be seen, a lie that was never meant to be told, a life he never dreamed he could have. Evan Hansen is about to get the one thing he's always wanted: a chance to finally fit in. Both deeply personal and profoundly contemporary, Dear Evan Hansen is a new American musical about life and the way we live it.
