Here are a few examples of logos I’ve designed for various organizations, exhibits, and businesses, as well as some branded materials that use the logos.* Your organization’s logo should be a simple symbol that embodies the spirit of your organization. I believe that simpler is better—so that it is memorable, and reproducible at small sizes in many applications. I can also build out brand guidelines to accompany the logo if you need that.
*I designed all of these materials except the Pixar advertisements.
