Hosted by Tower Grove Park, the 22nd Annual Martinis at the Mansion: A Speakeasy Soirée invites guests to step behind the velvet curtain and into an unforgettable evening of cocktails, music, and community in support of one of St. Louis' most treasured public spaces.

Hosted at the beautiful Compton Heights home of Larry and Sandy Koesterer, this year's event is inspired by the glamour, energy, and sophistication of the Roaring Twenties. Guests will enjoy signature martinis, delectable hors d'oeuvres, and an exciting selection of auction items while mingling with fellow supporters in an elegant and welcoming setting.

The evening will feature live entertainment by Second Generation Swing, a lively 17-piece big band performing classic swing favorites and timeless jazz standards. Whether you're dancing to the music, reconnecting with friends, or making new connections, A Speakeasy Soirée promises a night filled with charm, celebration, and unforgettable memories.

Proceeds support the Park's mission to preserve, restore, and sustain this historic urban park while enhancing the experiences that connect our community to this cherished public space.
