Areas of Expertise


William Gulya, Jr., is a member of the third generation of his family to work in the construction industry. His grandfather was a builder who constructed area homes out of old Army crates after World War II, because there was no wood in the area. Gulya's father, William, Sr., founded Middlesex Trenching Company in 1952 with a rubber-tired backhoe, one of the first hydraulically operated rubber-tire backhoes available.

When Gulya graduated from Union Technical Institute in 1972, he joined the business, which consisted of a dump truck, two backhoes and five employees meeting in a deli that had a payphone on the wall.

In addition, Mr. Gulya now provides contractor consulting - litigation prevention and expert consulting and expert witness testimony for attorneys, plaintiff and defense; contractors; general contractors; and government agencies.
