Started by John and Stacey Durkin, Onyx Corporation began in 1980 as a trucking company under the name Onyx Transportation. The name “Onyx” originated from John Sr.’s first truck, which was painted Onyx black. The company expanded through the years and in the early 90’s grew to include a 30 acre sand and gravel pit and quarry in Leominster, Ma. Roughly about the same time, they branched out into the field of excavation, performing local private jobs and eventually transitioning into larger public infrastructure work.
After receiving his degree in Landscape Construction from Penn State University, John and Stacey’s oldest son, John Jr., rejoined the team full time. Once again the company branched out, this time in the field of high end Landscape Construction. John and Stacey’s younger son, Cale, also joined the company full time, playing an important role in the excavation division.
In 2011, the companies name was changed from Onyx Transportation to what it is now known as, Onyx Corporation. The name was changed to better represent the company, combining its three divisions, Materials/Trucking, Excavation, and Landscape Construction. The company was also given a new logo. While similar to the original, the new Onyx logo is a representation of the family business. The X at the end of Onyx has three additional X’s after it, symbolizing John and Stacey’s three children, John Jr., Cale, and Harleigh.
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.
