Lake Forest's Citadel Theatre has announced the full cast and crew for its season opener - the satirical comedy EUREKA DAY, which examines the frequently contradictory practices of a fictional, highly progressive private school located in Berkeley, California. The play, which premiered in Berkeley in 2018, deals with topical subjects like vaccinations, privilege, and communication, utilizing sharp wit, farce, and intense dialogue to create laughter. It was produced on Broadway in the 2024-25 season and won the 2025 Tony Award for Best Revival of Play. Scott Westerman, the director of such Citadel hits as MISERY, A JUKEBOX FOR THE ALGONQUIN, THE MOUSETRAP, THE CHRISTIANS, and SEX WITH STRANGERS, will direct.
Leading Westerman's cast as Don, a member of the school's board who tries to keep the peace when the debate over whether or not the school should require vaccinations becomes heated, will be Steve McDonagh, who recently earned raves for his performance as "Man in Chair" in Theo Ubique's THE DROWSY CHAPERONE. The school's founder, Suzanne, will be played by Jennifer Ruffner, seen earlier this year in Citadel's ADMISSIONS. Cast as Carina, the parent of a black student at the school, is Alexis Primus, who appeared in TUTA Theatre's THE LONG CHRISTMAS DINNER in 2024 and 2025. Ethan Check, of 2023's GODS AND MONSTERS at Theater Wit, has the role of Eli, a stay-at-home dad. Carmen Liao (Raven Theatre's A DOLL'S HOUSE) will be Meiko – a single mother who deeply opposes vaccinations. Kristin Weed, seen recently on the North Shore in HAIRSPRAY with Uptown Music Theatre, will play Winter – one of the parents on the school's executive committee. Understudies are Jason Clark (u/s/ Don), Amy Yulish (u/s Suzanne), Kristin Weed (u/s/ Carina), Austin Rambo (u/s/ Eli), and Stephanie Fongheiser (u/s/ Meiko).
The production team is Scott Phelps (Producer), Ellen Phelps (Producer), Kate Espinoza (Stage Manager), Bob Knuth (Set Design), Devin Meseke (Scenic Charge), kClare McKellaston (Costume Design), Jodi Williams (Lighting Design), Petter Wahlbäck (Sound Design), Mitchell Pollitt (Master Carpenter), Randy Rozler (Properties Design), Kira Nutter (Intimacy Director), Devon Carson (Assistant Director), Kristin Weed (Run Crew).

In this hilarious 2025 Tony Award-winning satire, an elite private school is thrown into crisis when a mumps outbreak divides parents and board members over vaccines. As debates intensify and facts grow slippery, every solution only deepens the conflict. EUREKA DAY asks us to fully recognize the humanity of those we disagree with.
