What Connor & Gallagher OneSource does

Connor & Gallagher OneSource (CGO) is an independent insurance broker founded in 1997 and headquartered in Lisle, Illinois. The firm serves mid-sized businesses and organizations across 46 states with a 125-person professional team, delivering business insurance, employee benefits, retirement plan services, HR outsourcing and payroll, HR consulting, recruitment process outsourcing, and personal lines such as home and auto coverage. A separate wealth management practice is delivered through an SEC-registered investment advisor entity (Global Retirement Partners LLC dba Connor & Gallagher OneSource) with securities offered via LPL Financial.

The core technology asset is an integrated HRIS platform that consolidates business insurance, employee benefits, retirement plan, payroll, and human resource programs into a single paperless administration environment, accompanied by a client portal (CGO on the Go). Revenue is generated through insurance brokerage commissions from a broad carrier network (BlueCross BlueShield of Illinois, CNA, Liberty Mutual, Travelers, Hartford, Chubb, AIG, Zurich, Employers, West Bend), fees for HR and payroll outsourcing, retirement plan service fees, and investment advisory and securities revenue through the LPL/Global Retirement Partners arrangements. Pricing is quote-based and customized to client size, scope, and risk profile, with no publicly disclosed rates.

The go-to-market model is consultative and sales-led, combining dedicated in-house field consultants and licensed client support representatives with content marketing (blog, email newsletter, social, webinars) and event-based education. The company is privately held with no parent company or external institutional investors identified, and management emphasizes this independence as a positioning point against quarterly-result-driven competitors. Client and employee retention are reported at 97% and 95%, respectively, and the firm has received multiple industry recognitions including Inc. 5000, Business Insurance Best Places to Work 2024, IIA Agency of the Year, Best Practices Agency (2016), and SHRM Recertification Provider status (2025).

Direct peers

• OneDigital: OneDigital is the closest direct peer: an integrated insurance brokerage, benefits, HR, payroll, retirement, and wealth platform targeting mid-market employers. CGO's 'OneSource' positioning mirrors OneDigital's bundled service model almost identically.
• Hub International: Hub is a PE-backed insurance brokerage rolled up from regional agencies, providing commercial insurance, employee benefits, and personal lines to mid-market clients across North America — directly comparable to CGO's core brokerage model.
• USI Insurance Services: USI is a mid-market-focused insurance brokerage and consulting firm offering property/casualty, employee benefits, retirement plan consulting, and personal insurance — a near-direct match for CGO's product set and target customer.
• Alera Group: Alera Group is an integrated insurance, employee benefits, financial services, and HR consulting firm built via roll-up of regional agencies. It directly mirrors CGO's bundled mid-market offering and acquisition-led growth posture.
• NFP (an Aon company): NFP is an integrated insurance brokerage, benefits, retirement, wealth management, and HR advisory platform serving mid-market clients — a near-identical service mix to CGO before its acquisition by Aon.

Broad incumbents

• Arthur J. Gallagher & Co. Gallagher is a global insurance brokerage and risk management firm based in the Chicago suburbs. Despite the shared Gallagher name, AJG is a public incumbent that competes with CGO across commercial insurance, benefits, and retirement services for mid-market clients.
• Brown & Brown, Inc. Brown & Brown is a large public insurance brokerage that acquires and operates regional agencies serving commercial, personal, and benefits customers. It is a scaled incumbent competing for the same mid-market accounts CGO serves.
• Acrisure: Acrisure is a rapidly growing private insurance brokerage and financial services platform combining commercial insurance, benefits, and wealth management — competing for the same mid-market accounts CGO serves but at vastly greater scale.
• Marsh McLennan: Marsh is a global insurance brokerage and risk advisory incumbent that serves mid-market and enterprise clients with commercial insurance, benefits consulting (via Mercer), and risk management — a broad comparable for CGO's commercial insurance and benefits lines.
• Aon plc: Aon is a global professional services firm offering insurance brokerage, reinsurance, HR consulting, and retirement/wealth advisory. Through its acquisition of NFP it now competes directly with CGO in the integrated mid-market benefits and HR space.
