Merck’s head of HR to retire; replacement named

Kenilworth-based Merck announced Wednesday its chief human resources officer, Mirian M. Graddick-Weir, is retiring.

Graddick-Weir has been with the company for 12 years. She is being succeeded by Steven C. Mizell, who will join the company in October.

Graddick-Weir joined Merck in 2006 and will remain with the company until November to ensure a smooth transition.

“Mirian has made significant, enduring contributions as a member of Merck’s senior leadership team,” said Kenneth C. Frazier, Merck chairman and CEO. “Her work has positioned us to better attract and develop the workforce of the future.”

Mizell is joining Merck from Monsanto, where he was executive vice president and chief human resources officer since 2004. He will be responsible for the company’s global human resources and will serve on Merck’s executive committee.

“We are pleased to welcome Steve as our new chief human resources officer. His experience in leading human resources organizations, counseling leaders and board of directors and maximizing human capital around the world will make him a valuable contributor to our team,” Frazier said.

Prior to Monsanto, Mizell was senior vice president and chief corporate resources officer for Advance PCS, a prescription benefit plan administrator. He was also senior vice president and chief human resources and real estate officer for Zilog Inc., a technology company.

“Given Merck’s legacy, values and impact on the world, I couldn’t be more honored to join the company,” Mizell said. “I look forward to contributing to the executive committee and the organization at large.”

“I am proud of the Merck human resources team and its contributions to the company during my 12 years leading this world-class HR organization,” Graddick-Weir said. “I will leave Merck feeling satisfied that I have contributed to its long-term mission and improving its most important resource, which is people.”
