Why did Salas O'Brien pursue this particular merger?

The Take

What does the DWG merger signal for AV-adjacent engineering work in Salas O'Brien's growing footprint?

Salas O’Brien is a multidiscipline engineering firm that touches AV through building systems design, technology consulting, and the integrated project delivery model that larger institutional clients increasingly require. When a firm like Salas O’Brien absorbs a 50-year coastal South Carolina practice with deep healthcare, education, and government relationships, the downstream effect for the AV channel is straightforward: more Salas O’Brien engineers in the room at the specification stage for projects in those sectors.

DWG’s client base in healthcare and education is worth noting specifically. Both verticals are active AV spend categories with applications like patient experience systems, campus collaboration infrastructure, and house-of-worship adjacency in some institutional portfolios. Both lean heavily on trusted engineering relationships when selecting technology partners and integrators.
