Insights

Expansion Opportunity Horner & Shifrin is rapidly expanding its footprint across the US, including recent acquisitions and new offices in the western United States. This signals a growing need for scalable program management, integration of acquired teams, and standardized QA/QC processes to maintain quality across regions.

Transportation Growth The firm strengthened its transportation practice through the O’Neill & Company acquisition and added a VP of Transportation, indicating a focus on traffic and mobility projects. This presents cross-sell potential with state DOTs, municipalities, and regional transportation authorities seeking enhanced design-build and ITS capabilities.

Public Sector Focus A steady stream of engagements with state and local agencies (e.g., Missouri DOT and Town & Country projects) suggests ongoing demand in water, wastewater, flood protection, and infrastructure, making public-sector RFPs and alliance opportunities a prime sales channel.

Firm Strength Being 100-percent employee-owned with substantial growth recognition (Hot Firm List) reinforces stability and client trust. This can be leveraged to pursue long-term, multi-project frameworks with large municipal and federal clients seeking reliable partner firms.

Technical Capabilities A broad tech stack including GIS, AutoCAD, BIM-related tools, and cloud platforms supports integrated design and data-driven projects. This opens cross-sell opportunities for digital transformation, energy efficiency programs, and performance-based engineering solutions across utilities and infrastructure.
