Before becoming a CEO of Wolters Kluwer in 2003, McKinstry was chief executive of the company’s North American operations and had held a range of senior positions at subsidiaries, including chief executive of CCH Legal Information Services, now a part of Wolters Kluwer’s Legal & Regulatory division. Earlier, McKinstry held product management positions with CCH INCORPORATED, now part of Wolters Kluwer’sTax & Accounting division. She is both the Dutch company’s first American and first female chief executive. She has praised her board’s “courage” in making the appointment and credits her deep group experience in helping with “the transformation from print to digital … as quickly as possible”. Today three-quarters of Wolters Kluwer's revenue comes from online or electronic products, up from 71 percent in 2011, and 49 percent when the transition from print was launched at the end of 2008.
