Our Story
Our story began with Matthew Myles Walsh’s small carpentry business
in 1898. Since then, our company has evolved through four generations
of family ownership to become the multi-billion dollar contracting
business we are today, with more than 8,000 skilled tradespeople and
professional staff.
