Sarah Mattern is by far the most creative and adaptive designer there is. Our company builds complex web applications for many demanding customers – Sarah is the only person we will use for design and workflows. I have worked with Sarah for eight years now and she routinely creates outstanding work. 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, President
Thank you so much for delivering an outstanding microsite which completely embodies everything we wanted. You turned this around in an incredibly short time with minimal instruction. You are amazing and we are happy to provide a reference to anyone interested in your services. Thanks so very much for being the bright spot in our year!
Renee Strom, Vice President

It’s been wonderful working with you… You’ve been cheerful, professional and enthusiastic throughout the project… You possess a rare combination of outstanding design and project management skills and technical expertise, not to mention a willingness to explore and the intellectual capacity to learn new stuff quickly. It’s been a pleasure watching you create an attractive, functional website for us – we’ve received a lot of positive feedback about it.

Working with Sarah Mattern was a joy — she answered every question I had with thoroughness and patience. She brought great ideas to the table. She was knowledgeable, approachable, and reliable. I would definitely use her again for future projects.
I received a lot of positive feedback on our new website. One long-time customer said ‘this is the best investment LabSmith has ever made.’ Thank you so much!
Yolanda Fintschenko, Business Development
The best part of a project (like this website) is getting to meet and work with some incredible folks. Take Sarah Mattern, for example. This woman is the reason my blog looks the way it does and the reason I haven’t torn my hair out in the process of posting. She is 100% professional in all her endeavors. If you too think it might be fun to launch a website or design one, run don’t walk your fingers over your keyboard and get in touch with her.
Writes Better with Coffee
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.

A special shout out to Sarah Mattern of Mattern Co. for helping bring this project to life. Her guidance and expertise were priceless!
I had the greatest web designer (who put up with all of my requests, changes and general pickiness and particularity.) With her help, we hope we created a site that is simple, timeless and easy to use.

Sarah is great to work with. She’s proactive, efficient, detail-oriented, and a problem solver. She’s also a very talented designer. I’m very pleased with the brochure and website she created for 300 Santana Row and the multimedia presentation she created for City of Richmond.
Chris Hammer, CEO
Sustainable Design + Behavior
Thank you so much for your hard work and lightning fast turnaround. We got what we asked for and then some. You have a great eye for design and did I mention you are fast! It was such a pleasure to work with someone who understood our needs so quickly. Honesty, working with you felt practically effortless from our side of the fence. I’m so happy I’d wear a sandwich sign with your business name on it and stand on the street corners for a week. Is that weird? 🙂
Kris Young, Vice President
Sarah is a great partner in creating 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, Project Manager
I think your work is impeccable and makes running my practice so much easier. I have received countless referrals directly from my website. I would say that the money I paid you was money very well spent.
