For the next four years she was a staff assistant to the Speaker of the Illinois House of Representatives, including being Parliamentarian of the House from 1973 to 1975.

Upon joining the law school faculty in 1975, she began teaching both commercial law and constitutional law. She currently teaches Sales Transactions, Contracts, and Illinois Constitutional Law.

Within the legal community, she has been the Chairperson of The Armenian Bar Association, of which she is a founding member.  She is especially active in The Chicago Bar Association, which she has served for fifty years, including three terms as Chair of the Constitutional Law Committee.
