Profile bio

About Sean Sullivan

For 10+ years, I’ve been helping brands connect with their audiences by fusing brand voice and user experience. I’m a big believer that our stories, and the way we tell them, should evolve right alongside our users’ needs. That takes reframing old problems, finding fresh solutions, and staying open to what’s next.As a full-stack content lead, I’ve worked to bring big ideas to life from the ground up. I’ve helped shape the way you experience Mac, how you buy cars on Carvana, and how BODi keeps you healthy. Outside of work, you’ll probably find me testing the latest tech, catching a sporting event, or diving into the art world—all in search of inspiration that fuels innovation.

Listed skills include Creative Direction, Creative Strategy, Corporate Branding, Brand Development, and 11 others.
