What Rehn & Associates does

Rehn & Associates is a private third-party benefits administrator headquartered in Spokane, Washington. Founded in 1961 by Archie W. Rehn as a specialist for multi-employer Taft-Hartley trust funds, the firm has expanded into a full-service benefits administration provider offering Taft-Hartley healthcare plan administration, pension plan administration, self-insured medical, dental, and vision administration, COBRA continuation coverage, consumer-driven healthcare administration (FSA, HRA, HSA, VEBA, and Retiree Medical Trusts), consolidated billing, and ACA reporting (Forms 1094/1095). Its customers include multi-employer Taft-Hartley trusts, unions, individual self-insured employers with 35-plus employees, brokers, consultants, and associations, with the firm serving more than 1,500 employers, unions, trusts, and associations across the Pacific Northwest.

The company's technology stack combines proprietary claims adjudication software developed and maintained by an in-house IT team with WEX Health-powered online portals for COBRA and consumer-driven healthcare administration. These web-based systems deliver 24/7 access for participants, employers, brokers, and consultants to manage eligibility, billing, claims information, and compliance tracking. The firm operates on a professional services revenue model, generating fees for administering benefit plans on behalf of employers and trust funds; pricing is not publicly disclosed and contracts are customized through direct consultation. The firm employs a unionized workforce represented by United Food and Commercial Workers Local 3000, with several employees holding 15-to-40-plus year tenures supporting deep institutional knowledge in benefits administration.

In April 2025, Rehn & Associates was acquired by Harbour Benefit Holdings Inc. through its subsidiary Zenith American Solutions, positioning the firm within a broader national network of benefit administrators. The transaction preserved the Spokane headquarters, the Rehn & Associates brand, and its personalized service model under President and CEO David W. Kimmet, while providing access to expanded technology resources, operational scale, and cross-sell capabilities across the parent network.

Expansion highlights4 records

Direct peers

• Zenith American Solutions: Sister company under Harbour Benefit Holdings (the acquirer of Rehn in April 2025); operates a national third-party administration platform for Taft-Hartley and multi-employer benefit funds, offering directly overlapping services including claims adjudication, COBRA, and pension administration.
• Total Administrative Services Corporation (TASC): Large national TPA offering COBRA, FSA, HRA, HSA, and consumer-driven benefit administration for employers and Taft-Hartley groups; competes head-to-head with Rehn's CDH and COBRA service lines through its Universal Benefits Account platform.
• Further (formerly Conexis): National TPA providing COBRA, FSA, HRA, HSA, and compliance administration to employers and benefit consultants; offers comparable consumer-driven healthcare administration with similar broker/consultant go-to-market approach.
• BBP Administration: Third-party administrator offering COBRA, FSA, HRA, HSA, and retiree billing services; comparable mid-size TPA with multi-state employer footprint serving similar brokers, consultants, and Taft-Hartley-adjacent accounts.
• Benefit Resources: Mid-size TPA administering FSA, HRA, HSA, COBRA, and transit benefits for employer clients; comparable product breadth and go-to-market reliance on brokers and consultants to employers of similar size to Rehn's typical account.

Emerging players

• Ameriflex: Specialized TPA focused on FSA, HRA, HSA, COBRA, and commuter benefits administration with a tech-forward platform; smaller scale than Rehn but rapidly expanding on a multi-carrier debit-card stack directly competing in Rehn's consumer-driven healthcare niche.

Others

• WEX Health: Technology platform provider that powers Rehn's CDH and COBRA portals; competes indirectly via its HSA/COBRA/FSA offerings when it sells direct to employers, and represents both a partner and potential competitive threat to Rehn's consumer-driven healthcare services.

Broad incumbents

• ADP (TotalSource / Benefits): Broad incumbent offering PEO services and benefits administration integrated with payroll; while much larger and broader than Rehn, ADP competes for the same mid-market self-funded employer seeking outsourced benefits, COBRA, and CDH administration.
• Health Equity (WageWorks): Large consumer-directed benefits administrator combining HSA, FSA, HRA, and COBRA services following the WageWorks acquisition; competes with Rehn's CDH and COBRA offerings especially for employers looking for a single national vendor with broader scale.
• Paychex (HR/PEO): Major payroll and HR services provider with bundled benefits administration offerings; overlaps with Rehn's self-insured employer segment through its PEO and benefits solutions aimed at small and mid-sized businesses.
