Wisniewska began her career at her alma mater, Pennsylvania State University, and held several administrative positions at various Pennsylvania State University campuses throughout her early career. She later served as the dean for Temple University Ambler. During her tenure, she was recognized by March of Dimes' "Salute to Women of Achievement" in 2000 for her community contributions and fundraising efforts. In 2005, she became the chancellor of Pennsylvania State Brandywine, where she formed a strategic plan.

Wisniewska left her position at Pennsylvania State Brandywine in 2013 to become the chancellor for the University of South Florida St. Petersburg. During her time at USFSP, Wisniewska was credited by the Tampa Bay Business Journal for implementing a "durable strategic plan". She also acquired a $10 million grant, the largest gift in the history of the university, toward the naming of the Kate Tiedemann College of Business. Wisniewska left her position at USFSP after a significant email miscommunication between her and the USF System President Judy Genshaft regarding student evacuations and the closing of campus during Hurricane Irma in 2017. In response to Genshaft's request that she resign, Wisniewska defended her actions, stating she had advocated for an earlier campus closing, but it was denied. She resigned from her position as chancellor but in April 2019, filed a lawsuit against Genshaft and USFSP for breach of contract claiming defamatory information was released to media outlets after her resignation. In addition to her role at USFSP, Wisniewska served on Widener University's board of trustees from 2014 to 2015. She also served on the Chester Higher Education Council, a nonprofit organization created by university presidents of Delaware County, Pennsylvania.
