MNsure CEO Allison O'Toole announced her resignation at the health care exchange's board meeting Wednesday afternoon. O'Toole joined MNsure in 2014 as the director of external affairs. She took over the leadership position the following year.
"I'm so proud of the strong progress our dedicated MNsure team has made over the last few years, and I know they will continue to improve in the future," O'Toole said Wednesday.
MNsure credits O'Toole with boosting enrollment and improving customer service.
O'Toole will join a new non-partisan nonprofit organization called United States of Care. The group pledges to work with patients, caregivers, policymakers and other leaders to ensure that all Americans have access to quality, affordable health care regardless of their health status or income.
After O'Toole's resignation, the MNsure board named chief operating officer Nate Clark as the exchange's acting CEO.
"I'm excited to continue the great work started under Allison's leadership," Clark said.
Clark has served in the COO role since December 2016. According to MNsure, he's helped lead numerous improvement projects, including the addition of an online shopping comparison tool and the hiring of a private-sector company that's working to improve MNsure's system stability and performance.
MNsure Board chair Phil Norrgard praised O'Toole for her work Wednesday, and added his confidence in Clark's leadership.
"Given Nate's strong experience and expertise, we'll keep all of our improvement projects moving forward," he said.
Clark plans to take the helm of MNsure on April 14.
