About our Binghamton, NY Office

Binghamton is a small city that offers something for everyone. “Binghamton is a wonderful place to work, live and play – a key reason some of the best and brightest construction professionals are attracted to the area,” said Adam Green, who leads the Binghamton office. “Our local team is committed to delivering excellence for our customers and for the community we call home.”

The surrounding area, including parts of northern Pennsylvania, also provides a diverse array of work for the local LeChase team, which has completed projects for customers in higher education, hospitality, county government, healthcare and other markets.
