What is “The Jessica Effect?”

The “Jessica Effect” was named for the late Jessica Soto Pérez, former graduate student at the University of Maryland Baltimore County, member of the first cohort of PROMISE Peer Mentors. We wanted to invite, involve, and engage family members of graduate students in an effort to promote a more inclusive environment that caters to the whole person, and that values the importance of family and friends.
