Lamb Insurance Services

What Lamb Insurance Services does

Lamb Insurance Services is a New York-based insurance brokerage founded in 2003 that operates exclusively for nonprofit and human service organizations across the United States. The company places property and casualty coverage — including general liability, professional liability, property, sexual abuse and molestation, directors and officers, umbrella, auto liability, and cyber liability — on behalf of clients with carriers that specialize in the nonprofit segment. Its service offering extends beyond placement to risk management consulting, claims advocacy and management, carrier marketing coordination, and contract reviews. Lamb also operates a client portal (CSR24) supported by a mobile application (Applied Systems mobile insured) that enables policy management, certificate processing, policy change requests, and incident reporting on a 24/7 self-service basis, alongside an Aclaimant-powered claims management workflow.

The firm generates revenue through commissions paid by insurance carriers on placed policies, with pricing determined per client via quote-based, multi-year engagements and no publicly disclosed rate cards. Its go-to-market is sales-led, combining a direct client executive sales force, a phone-based inbound channel (1-866-481-LAMB), website-driven lead capture, and content marketing through industry insights, blogs, and SEO-optimized coverage pages. Lamb serves over 3,000 nonprofit and human service organization clients nationwide and self-identifies as the largest U.S. insurance broker exclusively dedicated to this vertical; the company has been recognized on the Insurance Journal Top 100 Property and Casualty agencies list in both 2022 (ranked #85) and 2025.

Lamb operates as a privately held company under parent entity Signers National, and has used acquisitions to broaden its footprint, completing four transactions between August 2023 and February 2024 — Eclipse Risk Insurance Services and Whittaker Agency in 2023, and Affiliated Insurance Agents and ISU Ballantyne Insurance Group in 2024 — bringing home health, religious organization, and adjacent nonprofit capabilities under the Lamb brand. The company is headquartered at 420 Lexington Avenue, Suite 2620, New York, NY, and is led by founder and CEO Josh Lamberg.
