B school in the late 70’s (MBA) and early 80’s (certificate). Both part time when the graduate B school was next to the late World Trade Center.
I got an "advnced professional certificate" in behavioral sciences & marketing in late 1980’s. Yes, pre 9/11, tho the building is still there. Stern School moved up to the Waghinton Square Campus, and the B school building in now a high school (wierd to see all those young kids going in & out!)
