About Us

In 1988, CalTech started as a software development company in the garage of Bob Calabrese. When several of Calabrese’s employees left he sought out help to strengthen the CalTech brand. Enter Will Welch and Brent McCasland. Will and Brent, business graduates of Angelo State University, opened Outback Computer Service in 1995 with an investment of $600 and two credit cards! They brought along Outback Computer’s loyal customer base, strong financials, and the competitive advantage to give CalTech the boost it needed. The two companies merged in 1998, maintaining the CalTech Brand. In late 1998, Mr. Welch and Mr. McCasland assumed full ownership of the company. Since then, CalTech has experienced significant growth and continues to attract both great clients and talent to our family. CalTech has been named as one of the Best Companies to Work for in Texas for eight years running by the Texas Association of Business, the Society for Human Resource Management, and Texas Monthly.
