About GUENTHNER ROBERT

Robert Guenthner served as Chief Legal Officer at Oak Street Health, Inc. beginning in 2018, at a U.S. healthcare company focused on primary care for older adults. His career reflects a corporate legal profile shaped by regulated industries and growth-stage organizations. Before joining Oak Street Health, he was Senior Vice President and Chief Legal Officer at National Surgical Healthcare from 2014 to 2017. That company operated surgical facilities and later merged into Surgery Partners, a publicly traded healthcare services company. This background suggests substantial experience with healthcare compliance, governance, operational structuring, and legal oversight in multi-site care environments. Prior to that, Guenthner was a partner at Dentons and its predecessor firms starting in 2005. In private practice, he worked in healthcare law and strategic advisory roles for clients across the sector, building experience with legal issues affecting healthcare operators, partnerships, and complex service delivery models. His move to Oak Street Health came during a period of expansion for the company, when the organization was strengthening its executive team to support growth and scaling. Guenthner’s academic background also combines legal and business training: he holds a J.D. and an M.B.A. from Washington University in St. Louis, along with a B.S. in Finance and Marketing from the University of Dayton. That mix of credentials likely supported his ability to bridge legal, financial, and operational discussions at the executive level. At Oak Street Health, his responsibilities would have been closely tied to governance, risk management, regulatory matters, and the legal framework supporting growth initiatives. Based only on the available sources, he stands out as an experienced healthcare legal executive with a strong track record in corporate counsel leadership and healthcare-sector advisory work in the United States.
