“It’s an honor to step into this role and continue supporting Mercy’s mission,” Day said. “Our goal is simple: Make sure Mercy has the resources to provide excellent care and invest in the communities we serve. By helping more people choose Mercy for more of their care, we are increasing access to some of the highest quality, best cost care in the industry.”
Day earned a bachelor’s degree in business administration with an emphasis in finance from Truman State University in Kirksville, Missouri, and an MBA from Webster University in St. Louis. He serves on the board for Access Academies, a nonprofit that supports education in St. Louis.
Day’s appointment follows the retirement of Cheryl Matejka, Mercy’s executive vice president and CFO, who concluded her 19-year career with Mercy at the end of 2025. Matejka was a key leader in building Mercy’s financial strength and guiding the organization through challenges such as changes in reimbursement, government regulations, COVID and supply chain issues.
