About

We’re Theory One, an agency that helps mission-driven organizations bring clarity to their work and communicate it with purpose across digital and built environments.

With nearly two decades of experience, we specialize in shaping identity, defining strategy, and translating vision into clear, cohesive narratives that connect with the audiences who matter most.

Our approach begins with inquiry. Through close collaboration, we work to understand your organization at its core—then develop integrated solutions across brand, digital, and campaign touchpoints that align with your goals and resonate in the real world.

If you’re looking for a partner who brings strategic rigor, thoughtful design, and storytelling that moves people to act, you’re in the right place. At Theory One, we design for clarity.

Thank you, TheoryOne, for building Orion a website that finally reflects our print magazine’s commitment to artistic excellence and centers our readers’ experience!

Orion Magazine

Theory One was instrumental in helping us refine our strategy and pushing us to think further about how our website fits into our larger communications strategy. They did key discovery work to understand our audiences and needs and came up with content and design approaches we had not imagined.

The Eric Carle Museum of Picture Book Art

Theory One excels at clear thinking, strategic planning, and creative problem solving—exactly what our complex, time-constrained project required to move forward. Their iterative, informed, and logical approach to our work together built our confidence, and left us inspired and set up for success.

American Ancestors

Thank you so much for your wisdom, patience, and dialogic spirit throughout this entire process. Every time I open up my browser to the new site I feel so refreshed and excited.

Ikeda Center for Peace, Learning, and Dialogue

The exhibition looks terrific—staff and visitors are very happy. The first floor looks complete for the first time in years!

MIT Museum

We looked for a development partner who was comfortable with an accessibility-first approach to design and development; Theory One was the perfect partner to work with and learn from.
