Who We Are

Founded in November 2018, NeuGen is a Shared Services organization based out of Madison, Wisconsin. In 1970, the not-for-profit WEA Trust was founded by the Wisconsin Education Association Council (WEAC). Well known for high-touch, personalized customer service, WEA Trust serves Wisconsin public employers, their staff and families throughout the state. In 2018, WEA Trust acquired another Wisconsin-based health plan, Health Tradition, in order to serve both public and private employees in the state. Today, NeuGen supports both health insurance companies in addition to providing medical management and administrative services to other healthcare companies.


Here at NeuGen, we are passionate about helping and giving back to our community. We are honored to be a Foundation for Madison Public Schools Adopt-a-School participant and look forward to spending time with, volunteering and donating to our school, Nuestro Mundo, each year.

In addition, NeuGen is a proud sponsor of the following organizations:

  • United Way of Dane County
  • Wisconsin Technology Council

Working at NeuGen provides me opportunities to work in all aspects of the healthcare space. I feel challenged and empowered when I come to work each day and surrounded by passionate and hardworking individuals.-Laura

NeuGen is a great place to grow and develop both professionally and personally. I find myself among a great group of colleagues who share their experience and work together in a spirit of mutual benefit. I'm proud to be a part of this exceptional team. -Brenda
