Coaching Staff

Kerri O'Shea
Women's Athletic Coordinator/Head Softball Coach/Title IX Deputy

Kerri O'Shea returns for her third season as the head softball coach at Joliet Junior College. During her first two seasons at the helm she has boosted the Wolves winning record to a total of 30 wins. During the 2017 season JJC produced 21 victories, a total number of wins the program has not seen since 2008.

O’Shea brings a wide range of coaching experience – from recruiting and mentoring at the NCAA DII, DIII, and NAIA levels – to the program. In addition to her collegiate-level coaching, over the years O’Shea has coached at the high school level and has worked as an independent contractor with local elite travel organizations on individual/group skills instruction. Coaching alongside local college coaches and mentors, such as Dick Smith, George DiMatteo, and Sarah O'Malley-Fisher, has prepared her to take on this role and build a solid foundation for our current and future JJC athletes.

During the 2014 and 2015 softball seasons, O'Shea joined the Concordia University-Chicago program under Head Coach Sarah O'Malley-Fisher. Her primary responsibility as an assistant coach was educating Cougar pitchers on the fundamental, physical, and mental dynamics of the game. In 2015, Concordia reached a program-best 15-9 in Northern Athletics Collegiate Conference play and a conference tournament berth. Their 19 wins overall marked the highest for a single season in CUC history.

In 2010 and 2011, O’Shea served as an assistant to varsity head coach Steve Paulsen at her high school alma mater Lincoln-Way Central. In addition to coaching, she continued her career at Robert Morris University as an Academic Advisor at the Chicago campus.

In 2009, O'Shea served her college alma mater, the University of St. Francis (USF), as an assistant coach for the Saints softball program for a fall season. She assisted veteran Head Coach Dick Smith with outfielder dynamics while also working with the pitchers. O’Shea obtained a high school relations position in the Admissions department at Robert Morris University prompting her to shift gears and continue her coaching career at the high school level.

O’Shea’s first collegiate coaching position was a two-year stint as a graduate assistant at Lewis University, under Head Coach George DiMatteo. Her primary responsibilities included recruitment, pitching instruction, and outfield dynamics. She helped direct the NCAA Division II Flyers to records of 38-18 in ‘08 and 38-19 in '09. During her time coaching at Lewis, Kerri earned her master's degree in School Guidance and Counseling.

While attending the University of St. Francis, she achieved three straight winning seasons, and was named Chicagoland Collegiate Athletic Conference (CCAC) Player of the Week on two occasions. O'Shea played for the Saints from 2005-2007 as a starting pitcher and an outfield reserve. She completed her career with a pitching record of 29-21 and posted a career-best 11 victories as a senior in 2007. She turned in winning seasons all three years, going 10-9 in 2005 as a sophomore, 8-4 in 2006 as a junior, and 11-8 in her final season. As a senior, she posted a 2.85 ERA in 113 innings with 91 strikeouts, as she held opponents to a .258 batting average. In the classroom, she was named as a Dean's List student and graduated with high honors.

Prior to college, O'Shea was a three-time varsity player for Dick Mandella at Lincoln-Way Central High School. She was selected to participate in the Super 60 All-Star Event comprised of 60 of the top high school seniors in Illinois and recognized as the 2003 tournament MVP.

"The goal of course is to always show progression on the field, but ultimately my priority is to shape the lives of our athletes off the field as well," O'Shea said. "I want our athletes to walk through the door and have these two years make a strong impact while preparing them for their future."

Coach O'Shea continues to put an emphasis on building a foundation for the future of the program.

"We will continue to recruit dedicated athletes who have a passion for the game. When you bring in student-athletes who are serious about their academics and development on the field, it allows for us to progressively build off of the previous season. You can see that result from this past season and it's exciting to think of the possibilities as we continue moving forward with the success of this program."

O’Shea and her husband Mike reside in St. John, Indiana with their three sons, Grady, Finnegan and Jameson.
