About us
Mary Catherine Marketing is a mission-based business helping nonprofits and small businesses do more good in the world.
With 20+ years of experience in the nonprofit and small business sectors, we truly understand what it’s like to lose sleep over limited time, tight budgets, and stretched-thin teams.
From mission-driven nonprofits—like Down syndrome organizations, environmental conservancies, and Catholic Newman Centers—to purpose-filled small businesses and creative entrepreneurs, we love partnering with people who care deeply and just need a little help. A stepping stone, if you will, to look polished and build the trust that fuels growth, revenue, and impact.
Why? Because the world desperately needs more of the good you have to offer. And you deserve a good night’s sleep.
Let us take a weight off your shoulders so you can get back to the work that matters most.
What We Offer
From storytelling to strategy, we offer hands-on support to help small nonprofits and businesses grow with confidence.
Whether you need a fresh website, a compelling video, help with copywriting, or just an extra set of hands, we’re here to make the work feel lighter.
How it all started
The heart of our story lies a place where it all began, filled with love and loss. Read on to explore our beginnings and uncover the roots of our mission, as well as the extraordinary bond that propels us forward.
