UnityPoint Health announced Dec. 7 Jon Rozenfeld as the new market president for its Des Moines market, effective Jan. 8, as David Stark has been appointed to a new role at UnityPoint Health.

Rozenfeld is a health care leader with more than 25 years of experience across several health care systems, including Johns Hopkins Medicine, Loyola University Medical Center, SSM Health St. Mary’s Hospital, and Ascension.

He most recently served as CEO of Vista Health System in Waukegan, Ill., where he focused on operational excellence, improvements in safety and quality performance, workforce recruitment and successful strategic growth efforts with physician partners. Rozenfeld has a bachelor’s degree and an MBA from the University of Pennsylvania.

“I wholeheartedly support UnityPoint Health’s mission and focus on creating a positive experience for every patient,” Rozenfeld said in a prepared statement. “I look forward to building upon the strong foundation that is already in place to provide great health care to this growing community. I’m also ready to partner with leadership, physicians, team members, donors and our community to advance health care for Central Iowa and beyond.”

Stark will formally transition to a new role as government, external affairs and philanthropy executive for the UnityPoint Health system that he was appointed to in July. In this position, he will focus on strategic legislative priorities, advocacy efforts, along with philanthropic and community impact initiatives across our entire footprint. He will also work closely with key stakeholders and elected officials to support UnityPoint’s workforce, physicians and providers and the community it serves.

“We look forward to what our future holds under Jon’s leadership as we grow programs and services to meet the needs of our community and state, and we’re also grateful for David’s continued partnership in a new way on behalf of our entire health system,” John Schmidt, UnityPoint Health – Des Moines board chair said in a prepared statement.
