Horner & Shifrin is a 90+-year-old, employee-owned engineering services firm anchored in CAD and hydraulic modeling (AutoCAD Civil 3D, MicroStation, HEC-RAS, EPA-SWMM) with a senior-heavy engineering bench. Pain-point clustering around project profitability, invoicing, and resource allocation suggests the firm is scaling project delivery faster than internal operations — a common friction point for services firms transitioning from founder-led to distributed management.
