dentsu Appoints Adam Lester as Senior Vice President, Growth

dentsu has appointed Adam Lester as Senior Vice President, Growth, adding a new leadership role focused on supporting the company’s growth agenda.

Lester’s move comes as marketing and advertising agencies continue to adapt to changing client expectations, evolving media channels, and the growing role of data and technology in business strategy. Growth leadership within the agency sector increasingly involves connecting business development with client needs, identifying new opportunities, and building relationships across the marketing ecosystem.

The appointment also comes amid a period of organizational change at dentsu. The company has been working to strengthen its global management structure and execution capabilities, with an emphasis on supporting client growth and improving coordination across its businesses. Its revised global structure, announced in February 2026, reflects a broader focus on transformation and more direct alignment between leadership and client-facing operations.
