About Onyx Corporation
Onyx Corporation was started by John and Stacey Durkin in 1980, with early beginnings as a trucking company under the name Onyx Transportation. The name “Onyx” came from their first truck, painted Onyx black. In the 90s, the company grew to include a 30 acre sand and gravel pit and quarry in Leominster, Massachusetts- which is roughly the same time they branched out into excavation. These private, local jobs soon turned into larger public infrastructure work.
John Sr. and Stacey, along with their sons, play an active part in the day to day operations of the business. Currently the company employs 90+ team members, many of which have been with the company for over 15 years. The company views its employees as an extension of the family. This is reflected in the pride and dedication evident in their everyday work, and we couldn’t be prouder of where we’ve grown to after 40 years.
