Licensed Structural Engineers in Oregon, Washington and California
Johnson Broderick Engineering’s professional engineers are licensed in Oregon, Washington and California. Oregon law doesn’t allow us to stamp plans prepared by someone else, so every set of drawings and calculations we seal is work our own office prepared.
