Strategic Marketing & Creative

Hi! I’m Andrea (On-dre-uh), born in San Francisco, raised in Portland, and creatively shaped in Seattle. I’m a marketing and communications professional who blends strategic thinking, creative problem-solving, and a genuine love for bringing brands to life.

With 8+ years of experience across in-house and agency environments, I’ve worked at the intersection of brand strategy, integrated marketing, creative development, content, and communications. I’m especially drawn to the space where strategy meets storytelling: helping organizations communicate who they are, what they stand for, and why it matters to the people they’re trying to reach.

My work spans integrated campaigns, brand development, digital and content marketing, events, client engagement, thought leadership, and creative production. I’m comfortable moving between the big picture and the details—developing a marketing approach, shaping a story, building the creative, coordinating partners and stakeholders, and making sure everything comes together consistently and on time.



Some things I love….

Why work with me?

Working across different industries and teams has made me adaptable, collaborative, and comfortable navigating competing priorities and perspectives. I bring a balance of strategic thinking and hands-on creative execution, always grounded in business objectives, audience needs, and thoughtful brand stewardship.

Outside of work, you’ll usually find me exploring the Pacific Northwest, attending art walks and music festivals, discovering new restaurants, wandering markets for fresh flowers, or enjoying a good city skyline at sunset—with an iced chai always in hand. I’m deeply inspired by Seattle’s creative culture and love supporting local businesses, artists, public spaces, and community-driven work.
