Our Story:

Reimagining
Healthcare.

Succeeding Together.

Castell started with a desire to improve healthcare for everyone—payers, providers, and health systems. We believe that it takes cooperation, focus and dedication from all sides to make great change in healthcare, and we’re helping to accelerate that change.

Castell.

For more than 300 years people have built human towers – known as castells – around the Catalonia region of Spain. These towers often require more than 1000 people to build. Our name represents this same building and creating together. Together, we are more than the sum of our parts, and we use our determination, focus, and shared vision to reach our goals. As a Catalonian castell demonstrates, when everyone is aligned, great things can happen.

Built From Experience.

Castell is built on our success in managing health—specifically, a proven value-based clinical care model called Reimagined Primary Care. Originally created by Intermountain Health, Reimagined Primary Care successfully implemented fee-for-value in the trial clinics. After just one year, the program produced strong results:

  • 60% reduction in Medicare Advantage admissions
  • 25% fewer commercial insurance admissions
  • 20% decreased per-member per-month costs
  • Improved patient ratings
  • Improved physician satisfaction

We’ve built on that knowledge to create a best-in-class health platform with a comprehensive suite of offerings. Castell, an Intermountain Health company, is our vehicle to take our lessons learned and help everyone succeed in the future of healthcare.
