So the back should be more comfortable. It should have more storage room, like locking file cabinets. Things like that.” “Then it was a lot of learning curves around just purchasing the van, what we wanted the van to look like...I already had an idea of how we wanted to have a phlebotomy chair in there, how we wanted to have the shelves set up, how we could do testing, how we could have lights.”
Services Offered	• Harm reduction supplies (naloxone, fentanyl test strips, smoking supplies) • Nursing services • Insurance enrollment • Snacks, clothes, sleeping bags • Transportation support • HIV, Hepatitis C, and Sexually  Transmitted Infection testing and treatment • Post-Overdose Outreach • Recovery Coaching	“I mean, sometimes it’s not just MOUD...I remember this one time I got five financial counseling appointments. They wanted insurance...and also PrEP [pre-exposure prophylaxis to prevent HIV infection], Hep C treatment.” “That they’re there reliably with snacks, supplies, whatever else, is something that people have really enjoyed.” “Fentanyl test strips were a really big hit too.”
