Don’t take our word for it, hear directly from our employees! Download a short profile of one of Gregg’s newest lead drillers, Miguel Hidalgo as he details what he loves about working for Gregg Drilling and why he’s been with us for 17-years.

Gregg is a family run business that has grown to one of the largest site investigation companies in California. We have always been focused on supporting our employees and their families. This is evident through our generous benefit packages, matching 401(k) retirement program, medical/dental employer-paid premiums, and the family friendly holiday parties and events. Many of our current employees are the children, relatives, spouses of original employees who are still with us 15, 20 and 30-years from when they first joined the company. We aren’t looking to just fill a job, but rather a person who wants to join us for their career.

Gregg Drilling is a minority owned business and part of the Sealaska family: For People, For Planet. We are proud to be a part of the focus on ocean health and environmental conservation.
