What's My Why: Official Kari Seitz

August 19, 2026

Kari Seitz, Mill Valley (Calif.)

Kari Seitz – the closing speaker at July’s Officiate Michigan Day in Grand Rapids – was one of the top American professional soccer referees and one of the most experienced female referees in the world. She is currently the vice president of refereeing for US Soccer and formerly served as the FIFA head of refereeing.

She worked four FIFA Women's World Cup tournaments (1999, 2003, 2007, and 2011), as well as three Olympic soccer tournaments (2004, 2008, and 2012), and is the only referee – man or woman – to officiate that many of both. Kari was inducted into the National Soccer Hall of Fame in 2026 and is a graduate of Brighton High School and Michigan State University.

So I was a soccer player, played soccer since I was 6. And at some point, I joined an all-girls travel team – that never happened. This was a long time ago.

Our coach required us together, every person on the team, to take the (officiating) course. Now, I believe he didn’t know anything about soccer. He was one of those parents who was reading it from a book and just cared about his kids. So he forced us all to take the referee course, and that altered the path of my life.

Be the Referee: Cross Country Interference

By Paige Winne
MHSAA Marketing & Social Media Coordinator

October 31, 2023

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – Cross Country Interference - Listen

I am running a great race at Michigan International Speedway. I’m about two miles into the 3.1-mile event, and I am on track to set a PR for the season.

As I run towards the next turn, a runner a few steps to my left, cuts right in front of me, causing me to slow down and nearly stumble. I regain my balance and keep going – but lose precious seconds during the altercation. Is interfering with a runner a penalty?

It is. If a race official sees a runner bump, trip, or run across another runner’s path causing them to change course or lose their natural rhythm, it’s interference. The runner charged with interference is disqualified. The runner who was interfered with continues on with his or her race.
