Her innovative approach has earned industry recognition for prominent British and global brands, including Boots, Direct Line, Bayer, and British Gas.

Catherine joins Assembly from Amazon, where she held the position of head of content marketing within Amazon Transportation Services and led SEO initiatives for Amazon-owned shipping software, Veeqo. Prior to Amazon, she was head of SEO at Havas Media. With over 12 years of SEO experience spanning both in-house and agency environments, Catherine has driven integrated marketing strategies for global brands, including Coca-Cola, Starbucks, Kia, and the Dundee Super Bowl campaign for Tourism Australia, which won a Cannes Lions in 2018.
