Our Clients Say
I Sleep Better At Night
“I sleep better at night knowing that representatives from Hollon + Cannon are on our projects to protect us from things we may not know or may not see. Their value is felt by every bit of weather that stays out of our finished indoor environment. Their service is an essential part of the design and construction process. I trust Hollon + Cannon and value their input on our projects.“
Kenton Heinze | President, Braun & Butler Construction, Inc.
Stands Above
“In my 25 years of construction experience with a school district, both Hollon+Cannon stands above most professionals with their collaboration and oversite on projects. They truly understand not only the construction side of projects, but have a firm grasp on how school facilities operate. KISD continues to utilize Hollon+Cannon and is currently under contract services with their company.“
