About Us

Meet Your Gregory Drilling Team

Larry and Bev Gregory started the tradition of excellence in drilling and dependable service in North Dakota back in 1975. Their sons Chad and Chris, both highly experienced Certified Well Drillers (CWD), manage drilling crews, and are proud to work side-by-side with their father, expanding the company and their drilling capabilities in Washington.

After nearly 50 years, we offer you more experience, more drilling crews, and better drilling equipment than ever in Washington. When combined with our no-nonsense approach to drilling and business, you can trust Gregory Drilling to be easy to work with and to deliver excellent results on your drilling job.
