AUCKLAND, Today: Thompson Spencer has welcomed Megan Clark Cook as Managing Partner. Known for integration and opportunity, she’ll help steer growth, shaping new and existing client partnerships while amplifying the power of the agency’s expanded offering.
After merging with Reason earlier this year, the agency united seven specialist businesses and an in-house production suite under one brand. This positions Thompson Spencer as one of New Zealand’s largest independents, with momentum growing daily.
Clark Cook joins at a crucial moment, ensuring the agency’s many capabilities hum together. Her focus is delivering seamless, full-funnel creative, media, and performance solutions for clients across New Zealand and abroad.
“Megan is an outstanding leader, with the rare ability to blend entrepreneurial drive with big-network expertise,” says Melanie Spencer, Co-CEO of Thompson Spencer.
“As well as proving her ability to build businesses from scratch, she’s driven growth for some of the world’s most iconic brands. Bringing her on board as Managing Partner is a huge win for us, and most importantly, for our clients.
“She will help harness and direct the incredible opportunities now possible with Thompson Spencer’s ever-growing expertise.”
