MEET Mollie Johnson

As Founder of Three Brooks Marketing, I help leaders become recognized authorities in their industries, to drive real results, open doors, and make sure their great work doesn’t go unnoticed.


With over a decade of experience in digital marketing and PR, I transitioned into personal branding after seeing firsthand the power of thought leadership to elevate ideas and the people behind them. Based in Washington, D.C., I’ve spent my career helping nonprofits, advocacy organizations, research centers, and social change entrepreneurs amplify their voices and expand their impact—because I believe ideas can change the world, but only when they reach the right audience.

At the Mercatus Center at George Mason University, I built and led a personal branding program that equipped experts to grow their influence—both within the organization and at academic institutions across the country. After five years in this role, I wanted to take this work further, partnering with professionals across industries to help them build standout personal brands and tell their stories with clarity and confidence.

Since then, I’ve worked with authors, entrepreneurs, and industry leaders to drive outcomes like:

  • Growing online platforms by thousands of followers

  • Increasing visibility by 100% to 5,000%

  • Earning coverage in Politico, The Hill, The Financial Times, and more

  • Opening new business opportunities worth thousands in revenue

  • Selling thousands of books and earning recognition in their fields

When I’m not helping clients get results they’re proud of, you’ll likely find me at the playground with my kids or squeezing in a strength workout at the gym.

The story You TEll is the current that carries An impact.

At Three Brooks Marketing, I help individuals and organizations gain the clarity, credibility, and visibility they need to make a meaningful impact. Whether you're an expert with big ideas or a business founder with bold goals, I craft strategic marketing solutions that move your message—and your mission—forward.

I specialize in personal branding that helps people stand out, build trust, and grow their influence. From authors selling books to business owners attracting new clients, I develop tailored strategies that connect with the right audience at the right time.

Over the years, I’ve helped nonprofit leaders engage stakeholders, experts launch successful podcasts and newsletters, and policy professionals establish themselves as trusted voices in their fields. No two clients are the same, and that’s exactly why every approach I build is custom-fit to your vision and values.

At Three Brooks, I’m here to help you gain momentum for your excellent work, and turn your message into lasting influence.

Your Journey, My Approach

Every powerful brand begins with a spark—an idea, a goal, a vision for something more. Turning that idea into impact takes clarity, strategy, and momentum. My approach is rooted in listening deeply, crafting thoughtful strategies, and building authentic growth—so your message doesn’t just make waves, it travels far.

Here’s how I make it happen:

Listen Deeply & Shape Your Brand Story

Whatever your ambition, I’m here to listen. I believe every strong personal brand begins with clarity, so I take the time to understand your values, your voice, and your vision. This is a vital foundation for helping shape your brand story that reflects who you are, where you’ve been, and where you're headed.

Craft a Strategy That Charts your path

I design a strategy that moves your message forward. From content creation to platform positioning, I map out how and where to show up—consistently and with purpose. This is where your message gains momentum, reaching the right audience in ways that feel authentic and aligned.

Grow your audience & Expand your Reach

Rooted in your strategic roadmap, I help you build systems and habits that keep your brand growing. Whether you're growing a newsletter, launching a podcast, connecting with clients, or mobilizing a movement, I guide you through a growth process—so your influence deepens and your impact expands.
