NEW YORK — Edelman has named three global sector chairs: Tish Van Dyke for food and beverage, Deidre H. Campbell for financial services and Amy Hemingway for energy. All three will report to Kym White, global director of sectors and global chair of Edelman’s health sector.

In this construct, Edelman is expanding its addressable market by accelerating opportunities for cross-practice and cross-geography support in some of the world’s most important industries.

“Our effort around sectors is designed to deepen the firm’s industry specialization and better organize existing firm expertise against it,” said Ben Boyd, president of practices, sectors and offerings. “At the same time, continuing to push forward and develop our market-leading practice capabilities, which are at the core of what we do.”

Edelman’s global sectors include technology, health, food and beverage, financial services and energy. Maria Amundson, former head of Edelman’s Silicon Valley office, was announced as the new global sector chair for technology in September. Sector chairs are responsible for client counsel, portfolio management, new business development and sector marketing.

As head of food and beverage, Van Dyke will continue to head a group of 250 professionals that include registered dietitians, public affairs and corporate reputation experts, agricultural policy and issues specialists and brand and commodity marketers.

As global sector chair, financial services, Campbell will lead Edelman’s global team of more than 150 financial services communications experts. Campbell joined the firm’s global corporate practice a year ago after working at several financial communications boutiques and global agencies.

As the global sector chair for energy, Hemingway leads Edelman’s team of more than 100 experts that serve diverse energy client interests including natural resources, power and cleantech. Since joining Edelman in 2006, Hemingway has managed campaigns for energy clients on energy and policy issues including access to energy, taxes,  prices, advanced technologies, air quality and emissions, crisis preparedness, safety and security.
