Portland State University does have a Department for Students with Disabilities.
Google "Portland State" and it will take you to the main site for PSU.
I am very sure PSU does have a DSD but the person running it should retire.
When I encountered their DSD back in May of 2007,
the dean is a crazy lady who does not understand Aspergers/Autism in its entirety.
Whenever someone tried to speak, she always interuppted them in the middle of a sentence.
If this turns you off, there is always Portland Community College, known as PCC.
