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

Sarah Mattern is a pleasure to work with. A consummate professional — creative and collaborative — she is driven to provide top notch design whether for print or online. I would definitely work with her again on future projects. Anat Baron
CEO, Ducks in a Row + StashWall
Sarah is a great partner in online promotions. She has an excellent sense of design and her projects are always delivered on time and with no technical issues. I keep going back to her with additional work because I know from experience that I’ll be delighted with the results. Liz Kaplan
