In the order they came.
Most people in dialysis are experts in one seat. I was moved through all of them — not by design, by accumulation. The floor, the unit, the bedside. Then I crossed to the other side of the curtain, into the industry, and for the first time saw the whole country at once — what worked, what didn’t, and how much of the confusion was baked into the system itself. The country was settled in layers, in the order its problems arrived. So was I. That is the whole reason I can draw this map: I did not study the territory from above. I accreted through it, then stepped back far enough to see it whole.

CNN
Metro New York, then the entire Northeast — Pennsylvania to Maine. The seat where the map began: from the other side of the curtain I saw programs across the country at once — the ones that could not start a transitional care unit because no one knew where to begin, the ones that stayed outsourced because they had never learned to run their own. Studied CRRT, SLED, and convection deep enough to teach nephrologists why the device fit the sickest patients.
VANTAGE 06
Quality & Safety
Inpatient HD and ambulatory PD — QAPI, survey readiness, program governance.
