Coaching Background:
Karen began her coaching career 16 years ago where she spent three seasons as the head varsity volleyball coach at Chassell Township High School in Michigan. In 2002, she earned Conference Coach of the Year honors after taking over a team that had never won a match and leading it to the conference championship the next year.

At Wisconsin, Sonders directed and managed five camps with more than 1,000 participants, 40 employees and five sites. During her time at Wisconsin, the team made two NCAA Elite Eight appearances.

Karen Sonders came to Northwestern as an assistant coach in March of 2006. Karen assisted in all aspects of the Wildcats' program, including on-court instruction , recruiting, scouting and the coordination of camps. She also coordinated the team defense, coached the outside hitters and liberos, built scouting reports, handled team travel and managed the Northwestern coaching clinic. In her first season with the program, three different Wildcats landed on Northwestern single-season top-10 lists.

In addition, middle blocker Chelsy Hyser earned AVCA All-Region accolades, becoming the first Wildcat to win an All-Region honor since 2002. Karen grew the Wildcats' volleyball camps into the largest they have ever been in just her first year at the helm of the sessions.

There were several seniors, juniors, and even a few sophomores who accepted full scholarships to top volleyball programs. And two of our athletes were selected to play on the USA Junior National Team — the only two players selected from Illinois.

In 2013, after taking a break to finish a Masters degree in Nursing from DePaul University and having a baby, Karen jumped back into coaching as the head coach of 18 Black. The team finished the Great Lakes Power League with a record of 18-6.

As a Lead Trainer, Karen oversaw the development of the juniors and seniors that made up the club's 18's age group. Karen prepared all ten seniors for their college volleyball careers: six of which were on full scholarships to DI schools, one on full scholarship at a DII university and three will be continuing on to play at DIII universities. In that senior group, Karen also coached 2013 USA National Team player, Taylor Tashima, who was chosen as a 2014 All-American after her performance at AAU Nationals.
