Bill Reason - President of Certified Lighting

Bill Reason


Bill purchased Certified Lighting in 2003. After recognizing the direct connection of lighting and signage working together; he acquired Professional Sign Services, formally known as Graphic Works, in 2012. He is from New Orleans and attended the University of Louisiana Lafayette where he majored in Computer Science with a minor in Business. Bill likes living in Chattanooga because he thinks it is one of the finest towns to raise a family. He also enjoys the community involvement behind the town and the diversity.

Bill loves his job because he gets to do something different daily. He also enjoys dealing with the most complex issues and finding the best problem-solving solutions for clients. Bill thinks the name of PSS relates ideally to how our industry is evolving. He thinks PSS will open the door to new business opportunities and better showcase all of our services to past and future clients.

Chad Moore - Operations Manager for Certified Lighting

Chad Moore

Operations Manager

Chad has been a part of Professional Sign Services and the Certified Lighting side of things since 2008. Not only does he manage the projects for Certified Lighting, he also has helped PSS with graphics installs and production. Chad is from Lookout Valley, TN and is a senior at UTC pursuing a degree in Industrial Engineering.

When Chad isn't eating, sleeping and breathing work he enjoys relaxing with friends and family. His favorite past time is lounging by the pool, watching and keeping updated on collegiate and professional sports. He also claims to be quite the Netflix watcher. In the next five years he would like to mark "running with bulls in Spain" off of his bucket list.

Chad's favorite part about being on the Certified Lighting team is getting to experience the satisfaction in our customer's eyes after we help them with their needs. He believes that his growing position with Certified Lighting will allow him to interact with clients and let them know we are more of a full service sign and lighting company rather than just a basic lighting business.

Certified Lighting Team Members

Team Members


There are several team members from the staff that work on the Professional Sign Services side of the house to electricians and installers that work out in the field. Working with the immensely talented individuals from the Professional Sign Services division, allows Certified Lighting a unique position of understanding how our installations will work from a visual perspective, the artists angle and the overall feel of the end product before we even begin the installation of many of our projects.

When our electricians and technicians have specific needs on a project that need to be conveyed to the designers, they have worked with designers from our own Professional Sign Services division as well as outside design houses and architect firms. Our team knows how to discuss the project on a level of understanding that is required at all different levels of the project.
