James Galvin
Brand and Marketing StrategyI’m a marketing and brand strategist with experience on both sides of the table; agency and in-house in New Jersey, New York, and now London, where I’ve been based for the past seven years. I’ve led brand and marketing strategy for start-ups and established organisations alike. Now, as a consultant, I focus on creating strategies that helps brands grow, stand out, and scale with purpose.Roy Weber
Campaign and DeliveryAs a campaign specialist, my focus is on lead generation, email marketing, SEO, PPC ads and web development. I plan, manage, and optimise campaigns from end to end, making sure every channel delivers. Whether it’s building high-converting funnels or improving performance, I help businesses turn strategy into measurable results.Sam Chen
Audience and MessagingWith a focus on audience insight, segmentation, and brand storytelling, I craft craft copy that connects and converts. I help brands tell the right story to the right people with clarity, purpose, and the right tone. Before One Week Marketing, I led content and messaging in-house. Now, I work with businesses to sharpen their story and make every word count.
