The OPSO offices are located in the River Forum Building just off of Macadam Avenue. Though our address states Macadam, our actual building is on Moody located just south of the South Waterfront Development (OHSU Tram) and north of the Avalon Hotel.


From Macadam, turn east (toward the river) on Hamilton Court. Turn left on Moody immediately after the railroad tracks. We are the last red brick building on the right – River Forum #1.
