A new mobile medical unit named for Layne Staley is set to bring medication-assisted addiction treatment straight to Seattle’s tiny home villages, rather than asking residents to trek across town for care. Backed in part by the Layne Staley Memorial Fund, the converted clinic-on-wheels is built to dispense methadone and other treatments right where people sleep and gather. The approach is meant to cut down on missed doses and help connect patients to longer-term services.
The Layne Staley Mobile Medical Unit is expected to operate Monday through Saturday, visiting at least three tiny home sites a day and serving up to about 250 people daily. Service is slated to start next Monday (June 15) at a tiny home village in Interbay, according to KING 5.
“People will see this man with his microphone singing out into the world,” Layne Staley’s mother, Nancy McCallum, said in remarks quoted by KING 5. Reflecting on the new unit, Therapeutic Health Services CEO Patricia Edmond-Quinn told the station that “hope starts here. hope is available,” as the organization rolled out the project.
Therapeutic Health Services, which manages the Layne Staley Memorial Fund, says the vehicle was developed with partial funding from the fund and is now in the final stages of licensing with the DEA and SAMHSA. The group says the unit will deliver medication-assisted treatment to residents of tiny home villages across the greater Seattle area. Therapeutic Health Services notes that partners worked with a manufacturer to equip the vehicle for on-site dispensing and counseling.
Where the unit will go
The first stops will be tiny home villages operated by the Low Income Housing Institute, with Interbay among the earliest locations on the schedule. Salmon Bay Village at 3435 15th Ave W is one of LIHI’s Interbay projects and has hosted tiny homes along with a safe RV parking program. Local reporting has documented the village’s location and role in LIHI’s Interbay portfolio, including coverage from MyBallard.
Why mobile MAT matters
Public health officials say bringing medication directly to where people live can lower barriers to care at a time when overdoses remain a serious concern in King County. County leaders and partner organizations have warned that although overdose deaths dipped in 2024, the trend swung back in 2025, largely driven by fentanyl, a pattern they have recently highlighted.
Therapeutic Health Services says it will post the mobile unit’s route and hours on its website as operations scale up, with the hope that predictable visits will support better treatment adherence and link residents to broader wraparound services.
