David Vienna is the mastermind behind the popular parenting-social-media entity The Daddy Complex. His viral post "The CTFD Method" catalyzed his success, which he followed up with debut book Calm the F*ck Down which was a bestseller for Knock Knock. Women's Health magazine named it the #1 Best Baby Book for New and Expecting Parents. He then followed that book with send-ups of parenting, pop culture, and politics: Drinks for Mundane Tasks, a cocktail recipe book for those with a to-do list; Are We There Yet?; a flow-chart book for parents stumped by their kids "bad decisions"; and Anyone Can Be President, an interactive guide to campaigning for and being the leader of the free world. He also wrote musicals for the San Luis Obispo Repertory Theatre, the screenplay for the independent film More Than Stars, and is currently developing a fiction podcast called Mysterious Chambers with Rooster Teeth, a Warner Bros. subsidiary.
