Jim O'Heir is an Emmy-winning actor and comedian best known for co-starring as Jerry Gergich on the NBC sitcom Parks and Recreation. He’s a Chicago guy who trained at Second City in the 1980s, then thrived in an independent improv and sketch group called White Noise, which took him out to Hollywood. O’Heir enjoyed tons of small guest-starring roles on TV for the past two decades before landing his big break with Parks and Rec. Now he’s hosting “Lullaby League,” an a cappella singing competition that debuted this April via YouTube and PopTV.
