Over the last three decades, the Leukemia Ball has reigned as one of Greater Washington, D.C.’s largest, non-political black tie events. The Ball has raised over $65 million for the National Capital Area Chapter of The Leukemia & Lymphoma Society since it began in 1988. Having grown from 375 guests to more than 2,000, the Leukemia Ball presents star-studded entertainment that in past years has included Jerry Seinfeld, Smokey Robinson, Jay Leno, Hootie & The Blowfish, Foreigner, Huey Lewis & The News, Diana Ross, Barenaked Ladies, Jim Gaffigan, and Andy Grammer. The 2019 Leukemia Ball featured entertainment by O.A.R. and Kathleen Madigan.
