About Construction LLC

Casias Construction LLC was established in December of 2003 by Domingo R. Casias, with the assistance of his son Frank D. Casias.  After retiring from Ft. Sam Houston National Cemetery, with 29 years of civilian service and 3 years of active duty, Domingo decided to start another chapter of his life by founding Casias Construction LLC.

Due to the success and growth of the company, Frank D Casias joined the company on a full-time basis as the Operations Manager in October of 2006, and assumed full ownership of the company in July, 2016.  Frank is a University of Texas at Austin graduate, who brings over 35 years of construction management and estimating experience to the company.  In December of 2018, Thomas S. Johnson and Frank D. Casias III were named Vice Presidents, assisting with the executive management of the company.


Though a relatively young firm, the staff of Casias Construction LLC averages over 20 years of construction experience.  Our knowledgeable and dedicated employees are the reason for our success, and are all considered members of the extended Casias family.

We pride ourselves on the quality of the projects we deliver and the relationships we have with our clients.  As a result, a lot of our business comes from repeat clients such as Sea World of Texas, H-E-B Grocery Company, San Antonio ISD, Northside ISD, Somerset ISD, LOK Properties, Schertz-Cibolo-Universal City ISD, The Beck Group, Haven for Hope and the U.S. Army Corps of Engineers just to name a few.

Casias Construction LLC is certified SBE, ESBE, HABE, and MBE by the South Central Texas Regional Certification Agency, MBE by the Central and South Texas Minority Business Council and HUB certified by the State of Texas
