History of Selective Insurance Group

The origins of the group date back to the 1920s in Branchville, New Jersey. Founder Daniel L.B. Smith, who managed a local chain of general stores, entered the insurance industry by selling a batch of personal and agricultural policies. This initial retail storefront operation laid the foundation for the current enterprise.

That small agency grew into what is now Selective Insurance Group, a company built on personal service and local decision-making. Selective’s timeline includes several turning points:

• 1926: Daniel L.B. Smith and a group of colleagues found Selected Risks Insurance Company with a $20,000 initial investment
• 1928: the company becomes a stock company, renamed Selected Risks Indemnity Company
• 1931: coverage expands to general liability, workers’ compensation, property, and municipal government insurance
• 1958: Selected Risks Indemnity and Selected Risks Fire Insurance Company merge into one carrier
• 1962: the insurer adopts IBM computer systems to automate policy processing
• 1984: the firm begins issuing flood insurance under the federal Write Your Own program
• 1986: the company changes its name to Selective Insurance Company of America
• 2002: Selective reaches $1 billion in net premiums written
• 2011: the insurer acquires two excess and surplus operations, later combined into Mesa Underwriters Specialty Insurance Company, extending its E&S reach to all 50 states
• 2019: John Marchioni is elected the company’s next chief executive officer, with Greg Murphy moving into the role of executive chair

That string of mergers, product launches, and leadership transitions turned a single-state agency into a super-regional carrier with a national footprint in specialty lines.

What does Selective Insurance offer?

The insurer organizes its business around three main segments. Each one serves a different part of the property-casualty market:

• standard commercial lines, covering contractors, manufacturers, private schools, professional offices, and small businesses
• standard personal lines, including auto, homeowners, renters, condominium, and umbrella coverage
• excess and surplus lines for harder-to-place commercial risks

Selective Insurance also underwrites flood coverage through the National Flood Insurance Program’s Write Your Own initiative, and it offers risk control services such as safety management, cyber breach response, and HR support tools for its commercial policyholders.

Distribution and operating model

Selective Insurance Group distributes its products exclusively through independent agents rather than a direct or captive sales force. The insurer describes its approach as a “high-tech, high-touch” model, pairing field-based underwriting and claims handling with agency automation technology. That combination lets local underwriters make decisions close to the customer while giving agents digital tools for quoting, billing, and claims.

The company has grown from a single-state auto and fire insurer into a multi-state commercial and personal lines carrier with a dedicated excess and surplus lines platform. Its long-term direction centers on underwriting discipline and steady expansion through its agent network, rather than rapid entry into new products or channels.
