About Dsi Event Group Inc.

With over 34 years of experience, we handle every element of event production, from high-quality, reliable audio production, lighting, video, staging, design, event coordination, equipment rentals, installations, event consultation and retail sales.


DSI Event Group formerly known as Dowlen Sound Inc is a Denver-based production company with over 30 years’ experience in event production. Dowlen Sound was Founded in 1979 by audio engineer Bret Dowlen, and has grown from a small, grassroots organization into a full-service production and events company with national and international clients.


Fueled by a passion for quality audio production, Bret Dowlen began designing audio equipment systems for local Denver events. DSI gained local exposure as a reliable, knowledgeable production resource, and in 1984, DSI partnered with Red Rocks Amphitheater for the first time.

Dowlen Sound continued to grow throughout the 1980s and 1990s, adapting to a changing market to win contracts with Red Rocks, Mile High Stadium, the Pepsi Center and the Colorado Symphony, continuing to successfully take on new clients of all sizes.

In 2013, Dowlen Sound purchased the assets of The Opera Shop (d.b.a. InOvation Group). Dowlen Sound, now operates under the name DSI Event Group, Inc. and acquired a new 32,000-square foot facility located at 6400 North Broadway in Denver, Colorado. With the expansion and growth of DSI Event Group, clients of all sizes can rely on DSI for all of their production needs.


We offer high-quality, reliable audio production, lighting, video, staging, design, event coordination, equipment rentals, touring, installations, event consultation and retail sales. Today we are a continually-growing national company with a diverse selection of high-quality equipment enabling us to produce hundreds of shows each year, tour with national acts, service numerous rooms and theaters regionally, and supply the Denver area and Rocky Mountain region with equipment throughout the year.

“It doesn’t matter if you hire us to do one show, a tour, or an entire sound system installation, you will always receive the same level of engineering and attention to detail that I’ve built this company’s reputation on.” -Bret Dowlen
