I’ve been happily making things for wonderful clients since 2006. I’ve worked with large companies (like Peets Coffee, Dagoba Organic, and Nutiva Organic), agencies (like the Northeast Ohio Areawide Coordinating Agency, US Army Europe, and the City and County of San Francisco), universities (like UC Davis and CSU East Bay), clean-tech companies, startups, small businesses, non-profits, and individuals.

I use a clear and inclusive process that involves you in your project. I ask questions, get your input and preferences, design/review/revise, build, and provide training so that what we create provides as much value as possible.

I also sincerely care about my clients. I want the experience of working together to delight you, and I want what we create to inspire you.

If you’re interested in working together, please contact me. I’d love to learn about your project!

Sarah Mattern is by far the most creative and adaptive designer there is. More importantly, she is easy to work with and dependable; so much so that our clients actually ask to work with her again. Sarah’s qualities are a fundamental reason our company is doing well. Kevin Knapp
CEO, Tierra Plan
Our MatternCo-designed sites regularly receive positive feedback for their clean, elegant designs and intuitive usability. Behind the scenes, Sarah has been a dream to work with, delivering three projects for us, each of which was on-time, on-budget, with no drama – only results. Mark Pastore + Chris Cosentino
