Mike O'Donnell, GM of the Honda Center in Anaheim, Calif., died Aug. 19 at his home in Yorba Linda, Calif., after a three-year battle with cancer. He was 46.

O'Donnell's career in public facilities, professional sports and arena management spanned over the course of 22 years. He spent the last 15 years at the Honda Center (formerly Arrowhead Pond of Anaheim), where he was hired in 1993 as the point person for the arena's final construction phases. During his first 10 years at venue, O'Donnell held such titles as operations manager, director of operations and assistant GM. In 2003, he was named VP and COO.

"Mike built a legacy in our industry that will never be forgotten," Tim Ryan, president/CEO of Honda Center, said in a statement. "His unrelenting work ethic and unwavering optimism set him apart both as a professional and a friend. Our thoughts and prayers go out to the O'Donnell family as they mourn this significant loss."

Along with overseeing concerts to the Honda Center, O'Donnell assisted in a number of events at the venue, including multiple NCAA events, the 2003 World Gymnastics Championships, the 2004 U.S. Olympic Team Trials for Gymnastics, and the 2005 World Badminton Championship.

Due to his illness, O'Donnell spent much of the past year in and out of the office, but contributed when health permitted, a Honda Center spokesperson tells Billboard.biz. During that time, a number of people at the venue stepped up to fill his role, so it is unlikely a replacement will be named, the spokesperson adds.

Prior to joining Honda Center, O'Donnell was operations supervisor at Los Angeles' Forum (then known as the Great Western Forum), which at the time hosted the National Basketball Association's Los Angeles Lakers and the National Hockey League's Los Angeles Kings.

O'Donnell is survived by his wife, Payge. Arrangements for his memorial service had not been made at press time.
