What Northwest Kidney Centers does
Mission
Northwest Kidney Centers' (nkc) mission is to promote the optimal health, quality of life and independence of people with kidney disease through patient care, education and research. Northwest Kidney Centers is a not-for-profit, locally managed provider of kidney dialysis, public health education and research into the causes and treatments of chronic kidney disease. Founded in seattle in 1962, it was the world's first dialysis organization. Among the eighth largest dialysis providers in the country, it is an influential model because of its high-quality services, deep community connections and generous donor support.
As stated on its FY2025 Form 990.
Programs
In the year ended june 30, 2025, Northwest Kidney Centers provided 285,069 dialysis treatments, essential to sustain the lives of people with kidney failure. Nkc served a total of 2,676 patients. The organization provided patient care in twenty (20) free-standing clinics and in eight (8) local hospitals and supervised self dialysis treatments in the homes of patients throughout the community. Nkc spent over $25.8 million more on the care of patients with medicare and medicaid insurance than the programs reimbursed us for. In addition, nkc provided more than $4.4 million in charity care. Northwest Kidney Centers' renal specialty pharmacy, a rarity in the nation, served more than 2,174 dialysis patients and kidney transplant recipients during the year.

The class program provides outreach to people who are not dialysis patients and may help them keep their kidneys healthy enough so that they never need to go on dialysis or can delay its onset. The patient-focused, evidence-based curriculum was developed by Northwest Kidney Centers. There were 884 chronic kidney disease education participants. In addition to its free classes, Northwest Kidney Centers connected with 102 community-based organizations, participated in 45 community events resulting in 15,725 touchpoints with people through our outreach efforts.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $221M to $260M (+17%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 2% · 2021 1% · 2022 0%. Grants only. Government contracts and fees sit inside program revenue.
1% of NORTHWEST KIDNEY CENTERS’s revenue is contributions — more donation-reliant than the typical peer (1% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 8 funders to 17 funders, grant income rose $316k → $369k.
13 of 49 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 21% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of NORTHWEST KIDNEY CENTERS’s funders (the co-funder graph). Top 30 of 49 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
NORTHWEST KIDNEY CENTERS has a broad base — no single funder exceeds 25% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
30% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund NORTHWEST KIDNEY CENTERS.
Largest funder’s share by year: 2017 79% · 2018 31% · 2019 38% · 2020 22% · 2021 21% · 2022 57% · 2023 62% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
38% of NORTHWEST KIDNEY CENTERS's funders are still giving 3 years after their first grant; 49% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
NORTHWEST KIDNEY CENTERS draws 52% of its grant income from funders outside Washington, across 14 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $633k arriving through sponsors registered in 9 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
