It seems like we redesign our own website about once a year or so. We took roughly a month to do this one, and a lot of that was just creating all the new media for it. We're super happy with how the home page video turned out (If you're on mobile, check it out on a desktop or tablet).
We're also happy with how it guides you through the site. It's a much more structured navigation process now. You can still get directly to the main things with the footer navigation, but the important parts are up top, and lead you to the next step in the process (About>What We Do>What We've Made>Contact). It makes it easier for new clients to learn about us, everything we do, and see examples of what we've done.
