History of the Tucson Office

For nearly 19 years, the CoreSource Tucson office has provided third-party administration services for numerous clients, which now include hospitals and healthcare networks, technology companies, the service sector and manufacturers.

Northwest National Life Insurance Company opened the office in 1990. The insurance company previously had acquired Northern Life Insurance Company of Seattle, and in 1995, unified both companies under a single name ReliaStar. And, CoreSource purchased the ReliaStar office in 1998.

Today, a total of 37 employees work in the Tucson office, including 25 in the Claims Department.
