Our company was founded by George W. Dillan, who returned to Darlington in 1919 to build a business and support his growing family. In the early years, he used a steam-powered wooden drilling rig that had to be pulled from site to site by horses. As the business grew, he invested in one of the first truck-mounted drilling rigs built by the Star Drilling Machine Company in Akron, Ohio.

That same spirit of hard work and forward thinking helped shape every generation that followed.

George's son Carl grew up in the business and continued the family tradition after serving in World War II. Later, the third generation, John W. Dillan, became deeply involved in the company and eventually purchased the business in 1976.

Today, the fifth generation leads the company forward. Todd W. Dillan serves as President, overseeing geothermal heat drilling and water well drilling operations. Mark J. Dillan serves as Vice President and leads the water treatment and pump service division.

What started with one rig and a small local operation has grown into a trusted regional company known for experience, capability, and straightforward service.
