The not-for-profit Roundabout, which presents Broadway and Off-Broadway productions, was Polk's beat at BBB, where Jessica Johnson was a fellow publicist. Johnson also moves to Polk & Company.

The Polk office will handle Roundabout's current and future projects, including The Mystery of Edwin Drood, Picnic, Talley's Folly, The Big Knife and the national tour of the 2011 Tony Award-winning musical Anything Goes. The firm will also work with producer David Binder (A Raisin in the Sun; 33 Variations) on some of his future commercial projects.

Polk began working on Disney's The Lion King during its first year and went on to create, execute and manage publicity campaigns for a wide range of corporate, commercial and not-for profit productions and clients including Disney, DreamWorks, Roundabout Theatre Company, The Heiress and Once. He has also created many publicity campaigns for celebrities, producers, cultural institutions, film/television projects and philanthropic causes.

Polk said in a statement, "I am eternally grateful to Chris Boneau and Adrian Bryan-Brown, who have been my mentors for the last 15 years. I have learned from the most respected and accomplished experts in the business. I made the decision to leave my professional family in order to grow, and to continue to challenge myself and further my personal commitment to my current and future clients."

Johnson began her career at Boneau/Bryan-Brown in 2003 and most recently managed the publicity for Broadway's One Man, Two Guvnors; National Theatre Live; Royal Shakespeare Company; and "Barrymore" with Christopher Plummer. She has also served as a press agent for Roundabout for 10 years. Polk & Company specializes in public relations, media strategies and social media.
