NEW YORK—Nancy Mensch Turett is leaving Edelman after 23 years to start her own consulting practice. Turett will also become a part-time senior counselor for Daniel J Edelman Inc.’s Zeno Group and its clients.

Turett has worked in New York, London and Paris in several key roles. From 1994 to 2000, she led the New York health division and moved on to become the founding leader of the global health practice. She also played leading roles in creating the Edelman Excellence program in 1997, the firm’s new brand identity in 2002, the creation of the global citizenship program in 2005 and Edelman Health Barometer in 2008. Turett also served as chair of Canada and Latin America from 2006 to 2009.

Most recently, Turett was appointed chief strategist, health and society, Edelman. As of March 1, Kym White has taken on the role of global practice chair for health.

Alan VanderMolen, vice chairman of Daniel J. Edelman, thanked Turett for “her visionary and passionate dedication, commitment and service to Edelman, our team and our clients.”

Turett added: “It’s been a joy and honor to be part of this company, one that I joined still in my 20s with the idea that in order to realize my own vision I would need some ‘agency experience.’ I soon learned that for someone who wants to work on issues material to business and society, Edelman is a destination not just a quick stop.”
