We are (as far as I know) the only shop who just does design and theming for Drupal. We funneled our years of theming expertise into the Fusion base theme, now the second most popular on drupal.org.

In 2005, I overhauled my personal site, found Drupal and fell in love with the power a front-end developer could have. After freelance theming for a couple of years, my partner and I decided that those other CMSes shouldn't have all the fun, and founded the first Drupal-only theme store.

TopNotchThemes loves to tackle both straightforward designs and more complex requirements, like supporting specific Drupal distributions. Our focus is on delivering a theme that administrators can maintain without having to come back to us for changes as their site evolves.

We love working with e-commerce Drupal sites, and are excited to be participating in the Commerce sprint before the camp. Mobile is also becoming an important space, and we're always eager to see what others are exploring in that space. We recently released a Fusion Mobile theme, and responsive layout & HTML5 are next on our list. And of course, we love to see familiar faces and meet people who are using our themes!
