Mills Well Drilling - Robert and Diane

Diane and Rob

Rob, the owner, is one of the few well drillers in the area with extensive cable tool experience, which has allowed him to become one of the best rotary method drillers in the area.

Nick is our Water Treatment Specialist, with over 20 years of experience in the Water Treatment industry.

Diane's brother Emerson lends a hand and drives the well driller from time to time.

In 2000, Robert's wife Diane came to work full time with the company and their business doubled in size. Robert and Diane greet all customers together, especially on new well appointments. All of our customers see one of them from start to finish on all jobs we do. This is the type of personal touch you receive from us.

Mills Well Drilling has a "Tradition of Quality and Affordability", and our mission is to do the job RIGHT the FIRST time and ALWAYS give personalized service.

Mills Well Drilling was formerly Slauch Well Drilling, a Cable Tool Well Drilling Company founded in 1927.

The Slauch's sold the business in 1988 to Mr. William Hayworth and Robert Mills Jr., and Mr. Hayworth taught Rob every aspect of the business. After Mr. Hayworth passed away in 1993, Rob took over the business and changed the name to Mills Well Drilling.
