      Vermilion is top notch. RMEQ formerly Out Boulder has worked with this team for decades. We have used them for rebranding and wayfinding and we would never consider another firm.

      We know people come to greenway.org to plan their East Coast Greenway adventures. With this redesign, we’re also highlighting the critical ongoing work to advance the trail, while offering efficient tools and resources for trip planning.Vermilion did an outstanding job helping us speak to the Greenway’s varied audiences. The new site is both highly functional and visually compelling, and I’m excited for our supporters to explore it.

      Jake Wells's Review Sourced from Google

      Outcome = awesome and unique yet simple logo that I love. Process = Sean really understood what I was after, helped me articulate it better, he was creative with good ideas/suggestions along the way, and we did multiple rounds of revisions/tweaks until it was just what I was after.

      Kristen Stephen's Review Sourced from Google

      Sean recently presented on SEO to an entrepreneurial group which I am a part of. He took a concept that can be rather confusing and translated it into an easily digestible format. He clearly answered all of our questions and gave us several actionable items that we could immediately take, to improve our website SEO. I’m very grateful his assistance!

      Sean's depth of SEO knowledge translated to sharing high quality and targeted information to our group. His ability to listen, quickly understand and analyze our questions, and identify actionable steps to improve our websites was extremely helpful!
