Houston-Area Schools

We first developed our identity as a trusted security solution provider by supplying CCTV systems to Houston-area school districts in the 1990s. After serving nearly 40 districts and countless campuses, Design Security Controls developed a reputation for providing educational institutions with quality systems and support.

Digital Boom

After the security industry’s digital boom, we built on our reputation by expanding into the next generation of security solutions. This opened up a variety of new industries to embark on, including government, commercial, and industrial.

Serving The Thousands

Since our inception, we have served thousands of clients in Southeast Texas by providing reliable life safety and physical security solutions.

The DSC of Today

Today, we are known as DSC and our primary solutions have expanded to include fire alarm, professional sound, video surveillance, access control, and intrusion alarm systems. In 2014, DSC was purchased by Kate and Ryan Droll, who continue to operate the company today as partners in both business and marriage.

Our Ownership Story


In 2014, Kate and Ryan Droll purchased DSC together. Prior to becoming co-owners of DSC, the husband and wife team had been associated with the company for over 15 years while Ryan served in a leadership capacity with a former DSC affiliate.


Today, Kate and Ryan run DSC together, with Kate serving as CEO and general counsel and Ryan serving as the company’s president.


Kate is a Texas A&M University graduate, where she received her bachelor’s and master’s degrees. She is also a University of Houston Law Center alumna. Kate is an avid runner who has run five marathons and multiple half-marathons.

Also a graduate of Texas A&M University, Ryan has 20 years of experience owning and operating private enterprises. Outside of his duties as DSC president, he also leads DSC’s sales and design teams.


Ryan is passionate and knowledgeable about low-voltage system design, consultation, installation, and service. In his spare time, he enjoys sports, fitness, and Texas A&M football.


Outside of co-owning and running DSC, Kate and Ryan enjoy spending time with their family. They have four children together.
