Get to know Diem Digital Interiors

Diem Digital Interiors (DDI) was founded in 2003 by its current President and Owner, John Dorsey, after many years of entrepreneurial experience in the Information Technology field. Currently DDI is one of the top Residential and Commercial audio, video, automation and low voltage systems integrators in Texas. Our staff of industry professionals is comprised of personnel in many areas of specialization and expertise from sales and administration to field service, customer relationship management and project management. We seek to provide highly functional solutions at value oriented price points in the market.

One of our most critical strategic partnerships is with Control4, a top manufacturer of commercial and residential audio, video, lighting and automation products. We are pleased to announce that DDI recently earned the honor of Control4 Top Volume Sales Dealer in Texas and 15 other states in the Midwest Region.

In addition to our knowledge of the technology systems we design and implement, we bring a thorough understanding of the construction process, as your audio/video partner. Throughout the various phases of construction, we pay special attention to wiring infrastructure, trim and final system installation. We remain involved with your project and work closely with the general contractor and other sub-contractors to ensure successful completion and attention to detail.
