Maureen Duffy is originally from the United States, where she was a litigator in Chicago, first in private practice with Rudnick & Wolfe (now DLA Piper), then as a specialist in the area of children's rights. She worked in both the trial and the appellate divisions of the Office of the Cook County Public Guardian, and later as an administrator/attorney for the Illinois Department of Children and Family Services. Maureen has extensive trial and appellate experience. Before becoming an attorney, Maureen worked as an editor and writer in the publishing field.

Maureen holds a master's and a doctorate in law from McGill University, where she was awarded the O'Brien Fellowship for Human Rights and Legal Pluralism and a Social Sciences and Humanities Research Council of Canada Fellowship for her doctoral research. During her master's program at McGill, she was a researcher for the McGill Clinic for the Special Court for Sierra Leone.

The pleading was later published by the Criminal Law Forum. She also holds a Bachelor of Science degree in journalism from the University of Illinois at Urbana-Champaign and a Juris Doctor, Cum Laude, from Loyola University Chicago School of Law.
