Bold Strategy

 for a Better World.

Connecting brands with what people truly value.

Uncover
the Story.

Hi friends, nice to meet you! I’m Mary Austin Harrelson, an integrated marketing, brand strategy, & sustainability communications leader helping organizations understand what people really value and turn it into stronger brands, relationships, & business value.

Mary Austin Harrelson—NYC-based strategist specializing in sustainability, communications, and stakeholder engagement for public and private sector impact.

I’ve always been fascinated by some of the first choices we make every day: What should I eat? What should I drink? What should I wear? They may seem ordinary, but the products we choose become part of how we express who we are, build community, and shape culture.

That curiosity has quietly guided my career.

From pouring pints at Oskar Blues and Brooklyn Brewery to developing brand and engagement strategies for fashion brands like INTERMIX and ETRO, I kept coming back to bigger questions about value: Why do we value the products we choose? Where does that value begin? And if the things we value ultimately come from nature, how can we create greater value for people, products, and the planet?

Those questions eventually led me to earn my MS in Sustainability Management at Columbia University, where I deepened my understanding of the environmental, social, and economic systems behind the products, businesses, customers, and communities I’d spent my career working with.

My graduate research examining human well-being in conservation reinforced something I now bring to all of my work: environmental value and human value aren’t separate ideas. Stronger systems depend on understanding both.

Across more than a decade of experience, I’ve approached that challenge from very different vantage points. I’ve built integrated marketing campaigns, shaped brand positioning and content, created partnerships and experiences, developed CRM and customer journeys, analyzed audience insights, and helped organizations translate complex sustainability priorities into stories people can actually understand and act on.

Most recently, as Head of Marketing at Sustainable Brands, I engaged leaders from organizations including Costco, PepsiCo, Levi’s, Oatly, Grove Collaborative, Ben & Jerry’s, and WWF through integrated marketing and thought leadership. As a consultant, I’ve advised companies including Target, Estée Lauder, Unilever, Mondelēz, and Nestlé on ESG communications and digital reputation. And at NYC DEP, I helped rethink communications and customer experience for more than 835,000 New Yorkers.

Different audiences. Different industries. Different challenges. But the question I keep coming back to is the same:

How do we make what an organization is trying to do meaningful to the person on the other side?

I’m at my best somewhere between the big picture and making it real: asking questions, finding patterns, connecting ideas and people, and then building what resonates.

Because the strongest brands don’t simply sell products. They understand what people really value and build meaningful relationships around it.
