Mike Yantis brings over thirty years of construction and development experience to the Yantis Company management team. Mike serves as Chairman of the organization. Mike primarily concentrates his efforts on the review of Yantis pricing proposals, business development, special consulting on construction issues, and value engineering as well as strategic planning for the firm.

Mike is proud to have been a partner with his father, John Yantis, starting in the early 1980’s. Mike quickly assumed much of the management responsibility for Yantis operational and estimating functions. Under Mike’s leadership, Yantis built many of the relationships and processes that the company still utilizes. The company also grew over 300% from 1982 to 2003.

Yantis has successfully completed over $1 billion dollars of infrastructure projects spread across many hundreds of individual jobs under Mike’s direct management or oversight.

John Yantis, founder of Yantis Company, graduated from Texas A&M in 1953. After serving in the United States Military John went on to work for HB Zachry Company and later became an equipment salesperson. In 1965, at the young age of 33, John decided to found John Yantis Company. Together with his first equity partner, Norm Harwell, John turned $20,000 into what Yantis Company is today.

John started Yantis Company with the idea that he would be a specialist in jobs that other people would consider difficult. His first project was a 36” sewer main that was over 16 feet deep in rock. John conducted firsthand the blasting and laying of this sewer. Despite the difficulty, John’s first project turned a substantial profit and allowed John Yantis Company to continue to grow.

Over the years John has been heavily involved and honored for his business and civic activities around San Antonio. John managed Yantis Company alone from 1965 until the early 80’s when his son J. Mike Yantis joined the firm. Under John’s leadership the company grew from a utility firm to a full service turnkey civil contractor. Some of the notable projects John was involved with include: Central Park Mall, Ingram Park Mall, Loop 410, the New Braunfels Wal-Mart Distribution Center, and Six Flags Fiesta Texas.
