What H. A. Thomson Company does

H.A. Thomson Company is a privately held insurance agency founded in 1934 and headquartered in Chester Springs, Pennsylvania, specializing in municipal insurance and risk financing for the state's public entities. The company self-describes as Pennsylvania's largest provider of municipal insurance and risk financing services and was the first firm to customize insurance programs for Pennsylvania's public entities. Its product portfolio spans six core lines — Liability and Property Pooling (via PIRMA), Property Insurance, Liability Insurance, Automobile Insurance, Worker's Compensation Insurance, and Bonds (Treasurer and Blanket/Position) — complemented by Risk Management Services such as property valuations, playground surveys, loss control inspections, and workplace safety consulting.

H.A. Thomson generates revenue primarily through insurance premiums and commissions on coverage placed for municipal clients, with annual quote-based pricing tailored to each entity. In 1987 the company partnered with PIRMA (Pennsylvania Intergovernmental Risk Management Association), a member-owned self-insured pooling program that now serves over 600 Pennsylvania public entities and is governed by its members. The go-to-market is sales-led and relationship-driven, with a team of Producers and Account Managers working directly with Pennsylvania municipalities; distribution is entirely domestic within Pennsylvania.

The company relies on a traditional insurance agency model without proprietary technology platforms, augmented by third-party partnerships — IRM Claim handles property, auto, and liability claims intake, while EMC Insurance and AmTrust Group serve as workers' compensation carrier partners, and ePay Policy provides the online premium payment portal. Leadership includes Derek Giangiulio (Chief Operating Officer), Andrew DiProspero (Senior Vice President, Producer), and Graham Giangiulio (Head of Marketing, Producer), with the Giangiulio family appearing to play a continuous role across operations and marketing.

Expansion highlights3 records

Broad incumbents

• Arthur J. Gallagher & Co. One of the largest global insurance brokerages with a dedicated Public Entity and Scholastic practice that places property, casualty, workers' comp, and bonds for municipalities and school districts. Comparable to H.A. Thomson as a multi-line intermediary to government entities, though at vastly greater scale and geographic breadth.
• Marsh & McLennan Agency: National insurance brokerage with a Public Sector practice serving municipalities, counties, and public agencies across multiple states. Comparable offering to H.A. Thomson across property, liability, workers' comp, and bond products, but with broader geographic reach and larger institutional resources.
• Alliant Insurance Services: Specialty insurance brokerage with deep public entity and pooled-risk expertise serving municipalities, schools, and special districts. Directly overlaps with H.A. Thomson's municipal-focused product portfolio including pooling programs and multi-line public entity coverage.
• Wells Fargo Insurance Services (now Marsh McLennan Agency): Former large insurance brokerage with a public sector practice that placed municipal property, liability, and bond coverage. Historically comparable to H.A. Thomson in serving PA and other state municipalities with multi-line packages.

Direct peers

• Brown & Riding Insurance Services: Specialty insurance brokerage operating through a wholesale/retail hybrid model, arranging complex property, casualty, and specialty placements for public and private clients. Comparable to H.A. Thomson in arranging multi-line coverage for niche/exposed client segments through carrier partnerships.
• Trident Insurance Services: Independent insurance agency focused on municipal, school, and public entity risks, offering property, liability, workers' comp, and bond products. Closely comparable niche focus and product mix to H.A. Thomson, operating in adjacent states.

Emerging players

• Public Risk Management Association (PRIMA): National association that supports public entity risk pools and self-insurance programs. While not a broker itself, PRIMA is conceptually aligned with H.A. Thomson's PIRMA pooling model and represents the broader ecosystem of municipal risk-pooling alternatives against which PIRMA competes.
• York Risk Services Group: Third-party administrator and risk services firm handling claims, loss control, and pool administration for public entity and insurance carrier clients. Comparable to H.A. Thomson's risk management and claims-adjacent services (work done with IRM Claim partner).

Others

• EMC Insurance Companies: Workers' compensation carrier partner of H.A. Thomson. As an upstream carrier supplier, EMC is a channel relationship rather than a competitor, but represents the type of P&C carrier infrastructure that H.A. Thomson's brokerage model relies upon.
• AmTrust Group: Workers' compensation carrier partner of H.A. Thomson. Like EMC, AmTrust is a carrier partner in the value chain that enables H.A. Thomson to bind coverage for municipal clients; not a direct competitor.
