MEMBERSHIP MEDICINE SOLUTIONS
Primary care is under structural strain. Health systems are struggling with physician burnout, declining access, and unsustainable fee-for-service economics.
​
Tributary Advisory Group (TAG) helps health systems and physician groups explore membership-based care models that complement traditional primary care. These models can improve physician sustainability, strengthen patient relationships, and create new revenue alignment without abandoning insurance-based care.
TAG provides strategic guidance to organizations considering how membership medicine may fit within their existing primary care portfolio.
