Meghan O'Sullivan

Life Sciences & Healthcare Marketing Consultant
I’m a marketing strategist and storyteller based in Massachusetts, specializing in life sciences, diagnostics, and healthcare. I help busy teams communicate clearly, plan strategically, and execute consistently—especially when they’re stretched thin.

​Strategic Storytelling & Marketing for
Life Sciences, Diagnostics, and Healthcare​

I partner with marketing, commercial, and business development leaders to turn complex science into compelling stories that build awareness, engage buyers, and move opportunities forward. Clients work with me because I make their jobs easier: clear messaging, dependable execution, and the kind of strategic support that helps marketing and sales teams breathe again.
