For 23 years, T479 was the hub of the MEDEX Northwest program to educate physician assistants. Last month, the program shed the confines of that old classroom, moving into new digs that allow web-conferencing with colleagues in Anchorage and Spokane. The new space also encourages students to move desks for group collaborations. "That's what we really expect to be the big enhancement here," said MEDEX medical director Linda Vorvick.
