80 years of discovering land value.

Andrews & Foster, a family-owned, full service drilling,

exploration and development firm, has 80 years of experience serving clients ranging from individual homeowners, farmers and ranchers to multinational corporations. With expertise in several types of drilling and exploration, A&F has achieved excellence from its beginning. With the goal of bringing water to homeowners, ranchers and farmers in East Texas, M.C. Andrews Sr. purchased a single drilling rig in 1940, marking the official founding of Andrews Drilling Company. As rural communities grew throughout the 1940s, the demand for water increased; as a result, the company prospered. In 1952, Andrews’ daughter Betty married Donald D. Foster who later became an integral part of the company; so integral, in fact, that the company was eventually renamed to Andrews & Foster Drilling Company. With the help of Foster, the services offered by the company were expanded to include water well drilling for both individuals and entire communities, which is a service that remains a staple of the company to this day. Twenty years later, after learning the business inside and out, Foster’s son, Donald (Don) Foster, joined the family business full-time in 1982. Since then, Andrews & Foster has participated in numerous projects throughout the United States, Western Europe, and Asia. The family legacy continues today with Don, as company president, and his daughter Ashley, vice president.
