UnitedHealth Group Inc. is making changes to its senior leadership, following the retirement of Steve Nelson, chief executive officer of its UnitedHealthcare health insurance and benefits unit.
Nelson will be succeeded by Dirk C. McMahon, currently president and chief operating officer of Optum, the group's health services, technology and pharmacy benefit management business. McMahon has held numerous senior positions since joining the company in 2003, including oversight of UnitedHealth Group's enterprisewide operations.
Daniel J. Schumacher, currently president and COO of UnitedHealthcare, will become Optum president and COO. Schumacher's new role includes oversight of OptumInsight, the company's data, analytics and technology business, Optum Technology and Optum operations.
Schumacher joined the company in 1999. In March, Optum named Andrew Witty, the former GlaxoSmithKline CEO, as its CEO.
“At a time when UnitedHealth Group is performing strongly in the marketplace on multiple dimensions, we are advancing leaders who will improve the overall health and well-being of the people we serve,” David S. Wichmann, CEO of UnitedHealth Group, said in a statement.
