What people are saying about our products
Excellent training! This 8 hr class was by far the best training I have been a part of since I started my masonry career 20+ years ago! The crew at Conproco did a fabulous job organizing and performing the training . I also had the privilege to act as the proctor for this training thru SWRI. I would highly recommend it to anyone in or new to the industry! Great job Larry, Kirstin, Aaron, and Don!
