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.

LANDSCAPE CONSTRUCTION

INFRASTRUCTURE

DIFFERENCE?

It’s not just our depth of knowledge in excavation that sets us apart. We’re sensitive to the environment in every decision we make, reusing and recycling materials as much as possible, and we have extensive experience working with LEED-certified architects. We are also committed to safety: we’re fully bonded and insured, and our employees are OSHA- or MSHA-certified, with many trained in first aid – which means that you can rest assured that your site will be managed to the highest standard.
