About Us

Downing Diversified - a born leader in the horizontal directional drilling industry!

Jimmy Downing began gaining his extensive knowledge and love of drilling in 1989. His father purchased the first model drill manufactured by Ditch Witch. Also one of the first mini rigs to come to the Pacific Northwest.

Growing with the industry has given Jimmy unequaled skill rounded by years of hands on experience in most every facet of the business. 

Jimmy and his wife Diana Downing started a new chapter in 2012 forming Downing Diversified Directional Drilling.

Diana brings her construction and business management experience to the company along with proven start up business success.

"Growing with the ever changing, environmentally friendly, technology of trenchless installation is key to our goal of complete customer satisfaction."
