I honestly don't know you could call them I'm sure you could try it they will let you once then tell you of somewhere in your zip code area
If you live east of 82nd area and in Multnomah county they will serve you according to their home page. However, you may be able to explain your situation and if nothing else they would happily point you in the direction of services available to your area.
They serve the Portland metro area.
