Our Journeymen and Apprentices are among the best trained in
the world. Continuing Education classes are offered on a
regular basis to our Journeymen to keep them abreast of
changes and trends in the sprinkler industry through a
telecommunications link to the United Association.
In addition, our apprentices are given hands on training in
our state of the art valve rooms, CAD instruction in our
computer lab, as well as classroom instruction. This
training assures that our contractors and end-users get the
‘best and the brightest’ to design, install and service a
quality fire protection system.
No matter how big or small the project, our members work
safely, proudly, reliably and quickly ensuring that the fire
protection system will operate correctly every time and that
projects remain on-budget.
