Leadership Transition GSD&M is undergoing leadership changes with the long-time CEO Duff Stewart stepping down and President Lee Newman assuming the role. This presents an opportunity to position services around leadership alignment, change management, and business transformation communications as the new strategy foundation takes hold.

Growth Momentum With revenue in the 500M to 1B range and a history of growing client businesses, there is room to propose expanded scope services such as integrated brand platform development, performance marketing, and cross-channel activation to accelerate client growth.

Expanded Production Recent leadership promotions and hires, including a new Head of Production, signal a strengthened production capability. This creates upsell potential for end-to-end production services, studio capabilities, and faster time-to-market for multi-format campaigns.
