What Wrightson, Johnson, Haddon & Williams does

Wrightson, Johnson, Haddon & Williams (WJHW) is a US-based consulting and technical design firm specializing in technology systems for complex venues. Founded circa 1989, the firm provides integrated design services spanning acoustics and noise control, sound reinforcement, audiovisual systems, LED video and scoring displays, broadcast and video production, theatre planning, performance lighting and rigging, distributed TV/IPTV, video surveillance and access control, and structured cabling. Its core methodology combines Enhanced Acoustic Simulator for Engineers (EASE) predictive acoustic modeling with BIM/CAD documentation, and it maintains a vendor-neutral stance — declining franchise alliances with specific manufacturers — to optimize product selection per project. WJHW operates as a wholly-owned subsidiary of PMY Group Pty Ltd (Australia) following an April 2021 combination, with offices in Carrollton TX, San Antonio TX, Lakewood CO, and London, and active project delivery across the US, EMEA, and APAC.

The firm sells professional services on a project-based, fee-for-service basis to venue owners, architects, and general contractors across six primary segments: sports & entertainment venues, performing arts & theatre, education (K-12 and higher ed), hospitality & convention, government & civic, and corporate & infrastructure. Notable engagements include AT&T Stadium, Allegiant Stadium, Mercedes-Benz Stadium, MetLife Stadium, Madison Square Garden, Fenway Park, Wrigley Field, Yankee Stadium, and Adelaide Oval. Go-to-market is relationship-driven enterprise field sales, with growth supported by PMY Group's global reach and a principal-led team that includes former venue operators and theatrical technicians.

Revenue is generated entirely through professional services engagements scoped per project. Pricing is not publicly disclosed and is negotiated on scope, complexity, and client. Distribution is direct-to-client with no resellers, marketplace channels, or OEM franchises. The firm invests in its talent base (e.g., RCDD-certified structured cabling designers, ETCP-certified riggers, ASTC members) and relies on its landmark-project portfolio as its primary commercial asset rather than outbound marketing.
