Independent positive change agency Think HQ has appointed Victoria Gehrig as Chief Operating Officer.

Gehrig joins the agency’s national leadership team, bringing experience across agency operations, scaling businesses and M&A integration. She returns to the Australian market after six years in the United States, where she served as Global M&A Integration Director at dentsu.

During her time at dentsu, Gehrig led acquisition activity from due diligence through to integration across large-scale, multi-market acquisitions.

Before dentsu, Gehrig spent more than a decade at Isobar Australia, eventually becoming Group General Manager.

During that period, she helped scale the business from a 20-person digital agency into a 350-plus-person operation across four national offices, winning multiple ANZ Digital Agency of the Year awards.

In her new role, Gehrig will work with Think HQ Founder and Managing Director Jen Sharpe to strengthen the agency’s operational foundation across Melbourne and Sydney.
