When was ICS formed?

ICS was formed in 2000, by Cheryl Westeren and Gary Archibald, who combined, have over 60 years of claims administration experience.

How much experience does ICS have with public entities?

We have over twenty years of public entity claims administration experience. ICS was founded on public entity administration and has built its foundation on managing claims and providing excellent customer service to those departments. We know the challenges and nuances of navigating claims with public entities, and we appreciate the loyalty and ongoing relationships that we have with our public entity customers.

Can ICS customize our workers’ compensation claims program to fit our needs?

Yes, ICS can customize any claims administration program to suit the needs of our clients. Workers’ compensation claims administration is not a one-size-fits-all industry. We understand the needs of each client are different. Therefore we offer customized solutions to make it efficient and easy to work with us.

Does ICS provide any special reporting for its clients?

Yes, ICS provides custom reports for all clients. We can customize any report the way our clients would like to see them. We have a dedicated support staff that focuses on custom reporting because we get many report requests daily
