Think HQ Appoints Charmaine Griffith as Head of Growth

Positive change independent agency Think HQ has appointed Charmaine Griffith as head of growth, doubling down on its Sydney expansion. The position is a newly created role designed to accelerate the agency’s NSW expansion.

Charmaine joins Think HQ from Clemenger BBDO, where she has spent over two and a half years as growth director. Prior to that, she held growth leadership roles at VML, including growth director for Australia and New Zealand. She brings a wealth of integrated agency knowledge to the position, with prior experience at PwC’s CMO Advisory, OMD, and Initiative.

In her new role, Charmaine will drive Think HQ’s Sydney growth strategy, strengthening the 100 strong Melbourne-headquartered agency’s presence in NSW and beyond.

This follows recent pitch wins with Cancer Council Australia, Stride Mental Health and Raising Children Network.

She will join Sarah Wood on the Sydney leadership team, driving coordinated growth across Think HQ’s integrated approach to strategy, creative, PR, tech, and diverse audience engagement.

Think HQ founder and managing director Jen Sharpe said, “Charmaine’s appointment reflects the strength of our ambition in NSW, and nationally. From the first conversation, it was clear she truly understands our unique strengths in the market, and brings a proven ability to lead growth in complex, integrated environments. I’m looking forward to working together to bring Think HQ’s positive change approach to more clients and communities across Australia.”

Think HQ Sydney director Sarah said, “Charmaine’s one of those people who instantly lifts a room. She’s smart, curious, and genuinely invested in helping clients and teams grow. I’m so excited to have her on board at Think HQ Sydney as we build on our growth trajectory and keep driving positive change.”

Think HQ head of growth Charmaine said, “Think HQ has built something rare -- an agency that solves complex problems for major clients, while staying true to their values. That’s good growth, and exactly what I want to scale in NSW and nationally.”

Charmaine has commenced her role at Think HQ’s Sydney office.
