Well, I always told my students "Wikipedia is not a source!" - but.......
As it's the only "source" on this I have at hand, I took a look. The "Career" section of Rick's page mentions Alembic, his eponymous company, Westwood Music, and Highlander Musical Audio - but the only other company they credit him with time at is President of Gibson Labs West Coast R&D Division, '88-'92.
My guess is that he "designed guitars for" Cort in the sense that that is a copy of an Alembic........
