Joe Hayes

Project Manager

Joe joined Twin Oaks in 2000 as our lead brick paver expert. He created exceptional environments for clients, and was to a fault, a perfectionist when it came to measurements and angles. He was also a leader in teaching new team members the proper techniques for not only laying pavers, but understanding the importance of proper multi-layer base levels. Through the years, Joe has excelled in becoming a manager for all projects and has been honored by many clients with praise for his exceptional work and work ethic of his great team of builders.  Joe is IPCI Certified (Interlock Concrete Paver Institute).
