It’s all in the details

Creative leadership. Impactful design.

Stephanie Martineau

I’ve always been interested in the moment when information becomes understandable.

That interest eventually led me to graphic design, and over the past decade I’ve found my way toward educational publishing, where that question is particularly meaningful. A textbook, activity booklet, or assessment isn't simply a collection of pages. The design has to help someone find their way through unfamiliar information, understand what they’re being asked to do, and stay engaged along the way.

My work spans primary and secondary education, editorial publishing, print production, and digital content. I’ve collaborated with writers, editors, and creative teams to develop everything from individual learning resources to full-length publications. I particularly enjoy multi-page work, where typography, grids, recurring features, imagery, and pacing come together to create a cohesive experience.

I hold a B.A. in Graphic Design from Rhode Island College and continued my design education at Rhode Island School of Design. My approach is detail-oriented and practical: I like a strong visual idea, but I also care about the systems, specifications, and production details that make that idea work in the real world.
