CHICAGO — In an effort to accelerate growth, Golin has moved two agency vets into newly created senior leadership positions.

Carrie von der Sitt, who most recently served as head of US growth, has been promoted to global head of growth. Her remit includes leading global business development, along with overseeing Golin’s marketing including brand strategy, advertising, external communications and thought leadership.

Ron D’Innocenzo, Golin’s executive creative director since 2013, has been upped to North America chief creative officer. In the expanded role, D’Innocenzo will lead creative across the region, which includes overseeing the firm’s conceptual creators, graphic designers and content production teams. He will also take an active role in business development, elevating the agency’s creative delivery for its clients and prospects.

“We have a really good partnership and the two positions are very linked when it comes to the growth and business development of the agency,” von der Sitt said.

All of which are critical steps in growing the business with top-tier clients like Lego and Twitter, which Golin landed this year. “I held this role with a US remit and now we can take processes and make sure they cascade and are used around the world,” she said.

D’Innocenzo, meanwhile, said his primary responsibility is “up leveling” creative output across North America so that campaigns garner more attention. Doing so, he said, involves uniting Golin’s offices across the region around a creative vision. “Good creative ideas should just move a brand forward. Otherwise they are just good creative ideas,” he said.

Both von der Sitt and D’Innocenzo will report to co-CEO Matt Neale. “Together, Carrie and Ron are a powerful combination,” he said. “They don’t settle. They know how to motivate high-performance teams and bring an unparalleled energy and passion to their work.”
