I'm Catherine O’Brien, a creative concepteur and copywriter specializing in crafting narratives that bring brands to life. With expertise spanning both editorial and digital, I help houses shape their stories - through words, visuals, and experiences that resonate.

Whether refining a brand’s voice, scripting a campaign, or weaving together an editorial story, my focus is always on creating meaningful connections between brands and the audiences they inspire.
