MOC Insurance Services and our other divisions, San Francisco Insurance Center and Farallon Associates, have offices in California. 44 Montgomery, our main office, is a 43-story, Class 'A' office tower centrally located in the downtown San Francisco Central Business District. Designed by renowned architect John Graham (Seattle Space Needle) and built in 1966, it was originally the World Headquarters for Wells Fargo Bank and once the tallest building west of the Mississippi. 44 Montgomery has achieved a LEED Gold certification for an existing building.
