Tom Arnold wed Ashley Groussman in an intimate ceremony on Saturday in Maui, PEOPLE has confirmed.

More than 75 family and friends attended the ceremony at Shep and Renee Gordon's home, including actor Dax Shepard, who served as Arnold's best man. Andrea Groussman was the maid of honor and designed the couple's rings.

Arnold and home organizer Groussman met through mutual friends in April 2008. The two became engaged this past March at Arnold's 50th birthday party.
