- William K. Monier

History of A. J. Monier & Co., Inc.

For one hundred years, A. J. Monier & Co., Inc. has served the San Antonio commercial service and construction market with confidence, quality and integrity.  In 1908, A. J. Monier established the business with high standards and competence.  His son, Kurt, a graduate mechanical engineer from Texas A & M University, joined the company in 1935 and a tradition of trust was established. 


Three decades later, grandson William K. Monier, a graduate industrial technologist from Texas A&M University and also a journeyman plumber-fitter became a member of the family-owned business. William K. Monier followed in his father and grandfather’s footstep's to become President and CEO in 1977. A. J. Monier & Co., Inc. with its generations of service and effective quality construction has proven to be a leader in the performance of commercial, institutional and industrial projects in San Antonio.


The original red brick building circa 1922 still remains from the early days of A. J. Monier -- a testament of not only its strength but the strength of the company it has housed for the last 90+ years. The company that August Jacob Monier started behind his house on Culebra Road in 1908 now covers almost 20,000 square feet.


At A. J. Monier & Co., Inc. we take pride in our work. In the 21st Century we are constantly growing and changing, but one thing remains the same, our dedication to our customers.
