More than 200 U.S. law firms will participate in an Islamorada fishing tournament benefiting the Crohn’s and Colitis Foundation of America.

Bilzin Sumberg Baena Price & Axelrod partner and litigation group leader Mitchell Widom founded the Keymorada Tournament with his wife, Alicia, and brother, Glenn, following his daughter’s diagnosis with Crohn’s disease.

Money will be raised through an online auction, silent auction, law firm challenge, donations and raffle tickets Tuesday-May9. Greenberg Traurig won the law firm challenge this year, donating $12,500 to the cause.

Since its inception 10 years ago, the Keymorada Tournament has raised more than $4 million for the organization—$510,000 last year alone—and become one of the most successful fundraising fishing tournaments in the country.

Proceeds from this year’s event will be donated to the foundation and the University of Miami’s Elaine & Sydney Sussman Crohn’s and Colitis Clinic, which opened a year ago with funding from the tournament.

About 1.4 million Americans suffer from Crohn’s disease or ulcerative colitis. The disease is commonly diagnosed between the ages of 15 and 35.
