EOI Service Company, Powered by Centro, is a national benefits communication and enrollment firm that brings over 47 years of experience to the design, communication, and enrollment of core and voluntary benefits and other value-added services.

EOI communicated and enrolled the first-ever employer sponsored universal life plan in 1979 at Harris Bank, Chicago’s third largest bank. EOI also implemented the first micro-computer worksite benefit enrollment, the first combined universal life and term plan, and the first universal life with long term care rider plan. We expanded into the areas of benefit statement enrollments and core benefit enrollments in the late 1990s and currently offer state of the art technology in these areas. Today, EOI excels in the following areas:

- Expert evaluation of the voluntary benefit market
- Electronic core/voluntary benefit enrollments
- Custom-designed electronic and print communication campaigns
- Creation and distribution of total compensation statements
- Coaching employees to appropriate medical plan options
- On-boarding of technology platforms
- Dependent eligibility audits
- Replacement of existing non-performing voluntary benefit programs

Our scope of operation is national with roughly half of our business coming from the eastern United States and half from the western United States. We are active in enrollments that include one-on-one on-site employee counseling, call center enrollments, and self-service programs.

EOI is appointed, licensed, and represent clients in all 51 jurisdictions with regional offices in California, Colorado, Illinois, New York, and Texas.
