Stories that inspire.
Marketing that connects.

I specialize in turning complex, mission-driven work into clear compelling stories that hit the right people at the right time. With structure, empathy, and strong execution, I drive marketing that connects and inspires action.


Hi, I’m Marissa.

For more than 20 years, I’ve helped nonprofit organizations cut through complexity and focus on what truly matters. I bring structure, clarity, and heart to big, messy initiatives, translating strategy into marketing that inspires.

How I help

My services

  • Marketing strategy & implementation

    I provide one-time marketing strategy and ongoing implementation for nonprofits and small businesses, turning big ideas into clear messaging, effective campaigns, and tactics that drive real results.

  • Trainings & workshops

    I design and lead marketing trainings and workshops that help teams communicate more clearly, work more efficiently, and build confidence in their marketing. From storytelling to AI integration, my sessions are practical, accessible, and immediately applicable.

  • Fractional marketing

    I offer fractional marketing leadership without the full-time hire. Whether you’re in transition, launching something new, or need steady support, I bring structure, clarity, and momentum to your marketing. I’m available remotely, or hybrid in Sacramento, California.
