Our Story
Building a clinic model focused on the long term health of a growing panel of prepaid, satisfied & loyal members, to unlock a new relationship for value-based care.

History of Tribus
Making healthcare safer, more affordable and more personalized for providers, patients and payers alike.
Founded on the belief that it should be easier to provide the right care, at the right time, at the right cost. Our model is bringing that belief to life, improving outcomes and empowering financial sustainability along the way.
A decade ago, a team of healthcare executives asked themselves a question: What are the most pressing issues in healthcare, and how do we fix them? For the system to thrive, the adversarial relationship between payers and providers had to end. This called for an innovative approach, with economics and data shared freely across the continuum of care. It meant incentives for behavior – not punishments – supported with the right information and tools.
A Strong Foundation With Lumeris
Tribus is supported by Lumeris which has a proven model and provides data from working directly with hospitals, specialists and patients to help support the risk-based clinic operations of Tribus' senior adult care model. In addition, LumerisEngage technology helps orchestrate care and drive behavioral change, improving communication and the relationship between providers and patients.
