About Erin Noel Grennan
Yellowbelly Photography
Erin was raised just outside Chicago in Oak Park, Il. She attended college at Saint Mary's University for two years before leaving to study and intern with both The Gaiety Theatre, and the (now defunct, but she swears she had nothing to do with it) Black Box Theatre in Ireland. She began her professional acting career upon returning to Chicago and has been performing around the country ever since, including nineteen productions with Circle Theatre in Chicago, as well as sixteen productions over eight seasons at The Peninsula Players Theatre in Door County, Wisconsin. She is the recipient of the Connecticut Critic's Circle Award, Chicago’s After Dark and SAM awards, and is a Jeff Award nominee (ensemble and production for A MOON FOR THE MISBEGOTTEN). Elsewhere, Erin was honored with a Broadway World award for her role in the world premiere of THE OUTSIDER. She was also a Wilde Award nominee for her work in UNNECESSARY FARCE. Erin has been honored to originate roles in several new American plays, including MAKING GOD LAUGH, THE TIN WOMAN, UNNECESSARY FARCE, SHADY BUSINESS, SLOW FLOODS, THE OUTSIDER, THE ANGEL NEXT DOOR, THEATRE PEOPLE, and BESIDE MYSELF, the last of which she co-wrote with her husband, actor/playwright Paul Slade Smith.
Erin’s work can also be found on screens both large and living room sized on TV and film, including the multiple award-winning RESURRECTING MCGINN(S), as well as the series THE OTHER TWO, DR. DEATH, CHICAGO FIRE, CHICAGO MED, LAW & ORDER: SVU, BLUE BLOODS, FBI: MOST WANTED, and BULL, to name a few. She also pops up in umpteen (that’s right, I said umpteen) TV commercials, often behaving quite strangely, which… you know… is a real stretch for her. Erin was recently fortunate to be a part of the the new film, RUN AMOK, which premiered at the Sundance Film Festival in 2026.
Erin currently calls Brooklyn, NY “home base” with her actor/playwright husband, Paul Slade Smith, though they are leaning heavily into the idea of becoming bi-coastal, as they have recently fallen in love with southern California. (That last sentence was slightly enlarged to prove intent and to shamelessly try and drum up work. Okay, onward.) Erin is also a long-time animal rights advocate who volunteers with various protection and conservation organizations. She and Paul also somehow fell into the ongoing role of homeless animal fostering… still not exactly sure how that happened, but there seems to be no going back on it now. Additionally, Erin is an amateur photographer and has had her work displayed in galleries, plays, three album covers, two magazines and in one Irish pub, the last of which she considers to be one of the greatest accomplishments of her life.
