• Founder

    Red Seal union carpenter with 20+ years specializing in FRP and wood cooling-tower repairs and rebuilds. I’ve led projects across Canada (Nova Scotia, British Columbia, Alberta, and Ontario), also in a few American States and in Jamaica earning a reputation in the cooling-tower community for safe, on-schedule delivery. At GLCTI I lead proven union crews and work closely with industry-recognized engineers to pair field-tested craftsmanship with engineered solutions. My focus: rigorous planning, transparent communication, and verifiable quality—every outage, every rebuild.
