- (847) 293-8564
Karen grew up in Crystal Lake, IL where she competed for Sky High volleyball club and Crystal Lake Central High School. She was a three-year varsity starter on a team ranked in the top ten in the state all three years. In her time at Crystal Lake Central, she set a school record for most kills in a season, was an FVC all-conference selection, all-area selection, and Chicago Tribune all-state special mention as a setter and outside hitter.
Karen went on to accept a full-scholarship to play for Michigan Tech University (1998-2001), where she completed her degree in biomedical engineering. Karen played both outside and right side hitter and was named MVP in her sophomore year. A 3-time All-GLIAC selection, Karen finished her tenure as the school’s season and career leader in digs.
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.
Between 2003 and 2006, Karen served on the volleyball staff at the University of Wisconsin Madison as the director of operations. 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 was also the development director with Wisconsin Power Volleyball and in 2003, club director at the Fusion Volleyball Academy in Crystal Lake, Ill. In addition to her duties as FVA’s club director, Sonders served as facility manager for the Fusion Sports Center. With Wisconsin Power Volleyball in 2004, Sonders led her 18's team to its first Junior Olympic Nationals, preparing all 10 players for careers in collegiate volleyball.
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. She helped freshman libero Kate Nobilio to the second-best single-season dig total in school history, and coached Lindsay Anderson into the NU 1,000-Kill Club. Under Karen’s in-game instruction in 2007, Northwestern set a program record with 339.5 total blocks, holding opponents to a paltry .169 hitting percentage. 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.
Karen founded Wildcat Jrs. VBC in 2007, beginning with five teams ages U12-U14. Through it’s continued success, the club has grown to twenty four teams from U11-U18 and has become the premier club of the North Shore and Chicagoland area.
The 2012 season marked several firsts for Wildcat Juniors. The club graduated its first class of seniors, sending more than half to play D1 volleyball in college. 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. At the AAU National Championships, Karen led 18 Black to a 9-3 record, winning the Silver Division and taking 16th place in the 18 Open.
In 2014, Karen coached 18 Black to a 5th place finish in the 18 Open at the AAU National Championships in Orlando, FL. The team played a whopping 15 matches in 4 days, with a record of 11-4 including the team's crossover match against Peru in the International Division. Karen also guided the team to a 1st place championship and an 8-0 record at the JVA Midwest Challenge in Des Moines, IA with a huge wins over Nebraska Jrs and Iowa Rockets in the semis and finals.
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.
Karen and her husband, Dave, have two young daughters, Quinn (7 years) and Macie (3 year). In 2012, Karen completed her Masters in Nursing at DePaul University. Karen is a member of the AVCA, USAV and JVA.
