Diversified Technical Services

When Elio Castañuela launched Diversified Technical Services, Inc., in 1980, he envisioned a company with a fierce commitment to customer success and satisfaction. From those beginnings, DTSI developed a culture intent on providing the most innovative and advanced solutions to the increasingly demanding technological challenges facing governmental agencies. Although small in size, the organization gathered a highly experienced and knowledgeable staff, leading numerous projects in the U.S. and around the world, building a reputation for meeting deliverables on time.

DTSI is a leader in the systems engineering and IT services industry. With nearly four decades of experience providing quality and cost effective technical support services and solutions to a diverse customer base, DTSI applies time-tested skills, knowledge, and abilities in the management of its projects and contracts. DTSI also possesses a wide range of capabilities from software development to telecommunications and network support to legacy system migration and system modernization. As a CMMI® Level 3 appraised company and a successful graduate from the SBA’s 8(a) Business Development Program, DTSI’s Quality Control Processes guides DTSI in not only the operations of its contracts, but the management of the entire corporate body.
