Our Purpose

Live Life To The Healthiest

We believe that the health insurance industry should do far more than just provide access to doctors and cover or administer claims. The way we see it, health care plans should help people live healthier. Which is exactly what makes us different. As a health plan management and administrative services company, we’re leading the charge on everything from expanding network physician and provider options to creating innovative approaches to wellness, prevention and community well-being. That’s because at Quartz, we’re a company committed to good health.

High Quality Coverage.
Wellness Programs.
Broad Networks.

Philosophy. Imagine a future where health plans are equally as committed to creating wellness programs as they are to expanding provider networks – as committed to community health as they are to the customer experience. A time when health plans are designed, supported and managed by people who truly care about making every community they touch not only healthier, but also happier. We believe that day is today. At Quartz, we believe that the health plans we manage and administer can be an integral part of advancing and bettering humankind. This is our vision for the future.


Local Decision making.
Broader network access.

As Quartz grows, so do the provider networks we offer. This means that certain plans will offer access to the local physicians of UW Health, UnityPoint Health – Meriter and Gundersen Health System, including specialty care at UW Health’s American Family Children’s Hospital and UW Health’s University Hospital – rated best in Wisconsin by U.S. News and World Report*.
