Marin's family had initially wanted her to forgo any further education and get a job in order to help out the family financially as well as help her mother care for her siblings. Marin compromised by working during the day and attending East Los Angeles College at night. After graduating in 1980, she continued to take night classes at the Los Angeles campus of the California State University (CSULA). Marin graduated from CSULA in 1983 with a Bachelor of Science in Business Administration.
