SISCO

At SISCO, we believe in delivering more than just benefits administration - we deliver peace of mind. As a third-party administrator with roots dating back to 1980, we've grown from a boutique firm handling complex plan designs into a premier national benefits administrator serving over 600 employers and more than one million members.

Headquartered in Dubuque, Iowa, SISCO operates as part of the Cottingham & Butler family of insurance services companies - an organization with over 130 years of industry experience characterized by organic growth and zero debt. Our team of 1,300+ professional teammates spans the nation, bringing together ERISA attorneys, physicians, pharmacists, registered nurses, and health coaches to deliver comprehensive support.

What sets us apart is our commitment to the 'One Roof' service model, where we handle everything from claim adjudication for self-funded medical plans to insured ancillary benefits. We reject the industry trend of reduced standards and rising costs, instead choosing to administer employer plans with the same care and diligence we'd apply to our own benefit program. Our licensed call center representatives and 24/7 online portal, SISCO Connect, ensure members receive responsive, personalized support from enrollment through every milestone of their healthcare journey.
