About Us

With corporate headquarters and distribution facility in San Angelo, TX, the Principal Sloan team has 150+ years of combined experience serving the LED signage market.

We Speak Sign Language

At Principal Sloan, our mission is to simplify the lives of our customers by streamlining the sign lighting process and providing the tools necessary to plan and implement a sign fabrication or retrofit project.

“Our mission is to simplify the lives of our customers.”

People, innovation, and value are the core pillars of everything we do as we constantly seek ways to create or innovate our products to save time and valuable resources. The product development process at Principal Sloan starts from the needs of the sign builder or designer—not the other way around.
