About Sensenig & Weaver

Many years ago a drilling company was started under Titus L. Sensenig using cable tool machines. In 1973, Titus sold the business to his son, Floyd R. Sensenig. As the business started to grow, Floyd took on Ronald R. Weaver as his partner in 1976 and the business became Sensenig & Weaver Well Drilling. The company remained a partnership until the end of 2006. At that time, Floyd & Mary Sensenig formed a corporation continuing under the name Sensenig & Weaver Well Drilling Inc. At the end of 2007, Floyd passed away.  Mary and their son Brian Sensenig took over running the business.  Since then Mary has retired and the business is owned and operated by Brian.
