The Washington Mental Health Workforce

Key findings

• Washington registers 664.2 active providers per 100,000 residents. That ranks 7 of 51 jurisdictions, above the national 433.5. #
• Spokane County has the state's highest registered density (903.1 per 100k); 1 of Washington's 39 counties have fewer than 3 registered providers. #
• Counselors are the largest group at 66.2% of Washington's registered workforce, compared with 43.9% nationally. #
• 3,094 providers with a Washington practice address first entered the NPI registry in 2025, versus 3,301 in 2019. These are registry entries, not licenses issued. #
• 73% of Washington providers share a registered practice location with six or more in-scope providers. #

Providers per 100,000 by county

Providers are allocated to counties from their practice ZIP code. For 1 county with under 3 allocated providers or under 1,000 residents, we show the count but no per-100k rate, because numbers that small don't make a reliable rate. We also withhold the rate for 3 counties (Grant, Stevens and Asotin), where a single practice address holds at least half the providers registered there, typically a regional employer that enrols its whole clinical staff at one headquarters, which inflates that county and thins its neighbours. The same values appear in the table.

Provider-type mix vs the national picture

Each provider counts once under their primary taxonomy; the US share is printed beside each Washington figure for comparison.

When Washington's providers entered the registry

This chart shows active providers by the year they entered the NPI registry. Registry entry is not licensure. Clinicians typically register when they start billing, so this measures registrations, not the workforce itself. 2026 is a partial year.
