About Us

Establishing a Family Legacy

The roots of Pref-Tech started with Shaun’s parents, Charlie and Trisha Castillo, who owned and operated a cabling business called Integrated Telecommunications, Inc. (ITI).

In 1999, Charlie and Trisha merged ITI with several other companies to form Netversant Solutions, a technology company that spanned the United States. After five years with Netversant, they were ready to get back into small business and approached Shaun with the idea of starting a new company.

After serving five years in the United States Army, in 2005, Shaun Castillo made a commitment to start the new company with his parents. In May of that year, Trisha Castillo established Preferred Technologies, Inc. as a Texas corporation. Shaun joined the company in August and started with rebuilding an old, worn-out trailer to use as an office.

During the day, Shaun worked on that trailer. At night, his father taught him how to design cabling systems, estimate them, sell them, and install them. He also gave Shaun direction and resources to develop his understanding of the physical security market. His father officially joined the company on September 1, 2005. Pref-Tech generated income for the first time by installing a data and voice cabling system on two floors of an office building.

From its beginnings to today, Pref-Tech has successfully executed projects that extend from small data cabling jobs to large, complex, integrated security systems in environments ranging from portable classroom buildings to international airports. In all cases, the company has differentiated itself from the competition by following the business principles outlined below.


Pref-Tech’s Key Business Principles

Private Ownership

Shaun and his father are the only owners, both participate in operating the company, and both have a long-term, legacy mindset for the company. As a result, they are not influenced by outside investors and manage every aspect of the company’s operations. They focus on improving employees’ lives and delivering high-quality work to Pref-Tech customers with excellent service. Most of our competition focuses on delivering revenue and profit for shareholders.

Self-Performance

We believe in executing 100% of a project with our own employees. We do this for one simple reason. We can control quality better that way.

Competence

Our customers expect us to be experts in what we do. We, therefore, invest heavily in developing and maintaining our competencies. We have a great team of employees that can execute tasks ranging from aerial cable installation to custom software development. Put simply, we know what we are doing.

Project Management

Projects today are often complex. We believe that well-trained project managers are necessary to deliver the projects on time, to standard, and within budget constraints. Our project managers brilliantly negotiate project conditions, understand contractual obligations, and masterfully manage resources to achieve successful project completion.

Trust Relationships

We feel that we must establish trust relationships with our customers and vendors if we are to achieve long-term success. Therefore, we operate with honesty, fairness, and transparency.

Our business principles have proven themselves to be valuable. Today, we have a long list of satisfied customers, happy employees, and financial stability.

Their leadership met with us and we knew we were entering into a collaborative relationship that made the design and plan meet our needs and budget. Their sales, engineering, and installation teams are dedicated to delivering value and performance.
