Primary care is under structural strain. We help health systems do something about it.
Tributary Advisory Group (TAG) helps health systems and physician groups design and implement membership-based care models that restore physician time, strengthen patient relationships, and stabilize primary care economics — without abandoning insurance-based care.

WHY THIS, WHY NOW...
The squeeze is structural
Panels of 1,800–2,500 leave no time for the relationship. Workflow tweaks won't fix it.
It's a portfolio problem
Not fee-for-service vs. concierge. A spectrum of models that can coexist within one system.
Built, not theorized
We operationalized a middle-ground model inside an academic medical center — and turned it around.

“Working with TAG has been a game-changer for us.
Jim brings clarity, structure, and momentum to complex clinical and operational challenges. Our physicians are more engaged after his sessions, workflows are improving, and there is clear organizational buy-in. If we could hire him full-time to help scale our model globally, we would.”
