About

Rosen Goldberg Der and Lewitz, Inc. (RGDL) was established in 2003. The team at RGDL has extensive experience in both the theoretical and practical aspects of acoustical and audiovisual system design. We listen closely to each client to gain valuable insight into their acoustical objectives. We then work together, combining our individual talents to craft solutions to meet those objectives. Over the years, we have completed hundreds of projects for both the public and private sectors.
