Robert Steiner, managing partner of Kelley Drye & Warren’s New York office, takes the ice bucket challenge Thursday. The firm raised $4,400 for The ALS Association.

Thousands of people, including celebrities, have posted videos of themselves being doused with ice water and challenging others to do the same—or donate money. The campaign has raised $53.3 million for Lou Gehrig’s disease research from July 29 to Aug. 21, compared to $2.2 million raised during the same period last year, according to The ALS Association.
