Our Members
WSIA's membership is comprised of three groups - our employers, who operate their own self-insured workers' compensation programs; our associate members, who provide professional services to employers of both self-insurance and the state fund; and our service companies, who provide third party claims administration services to self-insured and other employers and groups. The following directory lists our members, with links to their own websites, as available.
