Achim Luder was named chief people officer at Mercer, effective Oct. 1, a spokesman said.
Mr. Luder replaced Marcelo Modica. Details on Mr. Modica's future plans could not immediately be learned.
Based in Frankfurt, Mr. Luder is responsible for the consultant's global people strategy, building a diverse workforce and inclusive environment for the 25,000 colleagues across 44 countries. He reports to Carmen Fernandez, chief human resources officer at parent firm Marsh & McLennan, and also joined the executive leadership team.
"He brings real passion for the success of our colleagues and a deep knowledge of our business to the role," said Martine Ferland, president and CEO of Mercer and vice chairwoman of Marsh & McLennan, in a news release. "During his time at Mercer, Achim has honed his understanding of our culture, our business and what makes our people successful. He leads with a combination of clear strategy, care for colleagues and clients, and strong execution focus — ideal capabilities as we reinvent to be successful in an evolving 'new normal.' With change comes new opportunity, and how we enable all of our colleagues to be part of the journey has never been more important."
Mr. Luder was most recently CEO of Mercer Germany and was replaced by Norman Dreger. Further details were not available.
