About Us

Well drilling and well services have been in the family for more than a century here at Nielsen Well Drilling & Service, LLC. We are knowledgeable about water and the land in the St. Johns, Arizona, area. Formerly known as Cowley Brothers, our company was founded three generations ago to put up windmills and drill wells for cattle ranches. Over time, we have earned the trust of the local residents by providing quality customer service, professionalism, and years of experience.

Today, using an environmentally friendly drilling process, we work hard to make sure all our customers receive the best solution to their needs, but also understand their own property and what the land is able to provide for them. Keeping you satisfied is our goal. We look forward to working with you, so feel free to contact us with inquiries and concerns.
