We provide government and municipal signs, apparel (shirts, hats, etc.), vehicle lettering and wraps
to customers in Yuba City, Marysville and the surrounding area. All types including community
centers, city halls, police departments, fire departments and more.


Your agencie's apparel can encompasses much more than a black t-shirt with white lettering. We are capable of giving you shirts, hats, hoodies and much more, in a style you’ll be proud to wear.


We take care of all of your sign needs, not just putting stickers on a board. Everything from vinyl to painted, wood to metal. Sometimes you need more than a banner stapled to your building. We also know the demands that public signage demands, and use the required materials to ensure your products last.


There are many ways to identify on your vehicles. We can take care of a single truck or the whole fleet. Simple door lettering all the way to a full wrap, and my personal favorite…. a little in-between.

Everything Else

There are many choices when having a website designed. Every municipality and government agency will need something different. For some, a simple site will be more than enough. Others will need more complicated and involved. Either way we are up on the latest ADA and government compliances to ensure your site meets all the requirements. This includes Special Districts. Don’t be sold more than you need.

What We Do

Using a blend of cohesive indoor and outdoor signage will pique the curiosity of motorists and passersby and entice them to see what products and services you offer. Having professionally made signage also provides you with the perfect opportunity to introduce your brand to your community and how your products and services will make their lives better.

However, with mediocre signs made by ordinary sign companies, your target audience will pass by, unaware as they go about their daily lives. You need to partner with a professional signage company who knows how to engage even the most distracted customer and entice them to see what you have to offer.

We can help you do just that! We have a proven track record of delivering effective, quality signage solutions to both big and small business owners, and we are eager to show you how our solutions will help you.
