Val Mindak President & CEO


Since 2009, Val Mindak has served as Park City’s CEO and President, leading the credit union’s mission of “helping members fulfill their dreams while serving our communities.” Her commitment to serving employees and nearly 20,000 members with excellence has been the driving force behind Park City’s recognition as the Mid-Size Business of the Year for two years running.

A financial services veteran, Val gained 23 years of experience as the Chief Operating Officer of Connexus Credit Union in Madison, WI. During her tenure at CCU, she furthered her professional education by studying at Wharton, Darden, and Cornell Universities, ultimately achieving the credit union industry’s top designation, Certified Chief Executive Officer, in 2004.

In addition to her role as an Executive Member of the Wisconsin Credit Union League’s board of directors, Val also serves as the Chair of the Governmental Affairs Committee, where she represents the interests of Wisconsin Credit Unions statewide. Her example of service also extends beyond her work with credit unions, as evidenced by her involvement with Ascension Hospitals, the Merrill Chamber of Commerce, Good Samaritan Foundation Board, and Merrill Rotary.

From professional pursuits to personal endeavors, one quality that distinguishes Val is her willingness to embrace sentimentality towards her members and friends. As she pours herself into serving her community, she cherishes anytime someone remembers her as fondly as she remembers them, and she has kept every note, card, gift, badge, and letter that she’s ever received.
