Zierden, a Minneapolis native, became the Minnesota Lynx's fifth head coach on December 13, 2006, replacing Carolyn Jenkins, who remained on the staff as an assistant. Before taking the Lynx job, Zierden served as an assistant with the NBA's Minnesota Timberwolves and Detroit Pistons. Zierden was also the head coach for the CBA's Pittsburgh Piranhas in 1994.
In 2007, Zierden's Lynx began the season 0–7, lost 10 straight in July and failed to get into the playoff race. They finished tied with a league worst 10–24 record.
On June 2, 2009, Zierden resigned as head coach of the Lynx. He is recognized as a major influence in the rebuilding of the team. They would go on to win a title in 2011 and lose in the championship game in 2012.
He accepted an assistant coaching job under Flip Saunders in Washington in 2009.
Zierden has two children, a daughter (Rachel) and a son (Isaiah). His son Isaiah plays college basketball for the nationally ranked Creighton Bluejays in Omaha, Nebraska. His daughter is very good in math and science.
- “With our team, I thought we would shoot the basketball a little better. I thought we would defend a little better at times. Those have been the biggest surprises and disappointments." — Zierden on the 2007 Lynx 
- “She has been utterly fantastic. She has taken fewer shots this year and her numbers are up across the board. We told her coming in that we needed her to take fewer shots because we needed more balance to be a successful team, and she's been great about that. Any success this team is going to have down the road, she is going to be a big part of it." — Zierden on Seimone Augustus 
- “I miss the charter flights, the huge per diem and the huge salary. That's what I miss (laughs). I don't miss the 82-game schedule, where you are flying all over the place and really missing out on your family." — Zierden on the NBA vs. WNBA
