Summer Du




Summer Du brings her extensive litigation experience to bear on behalf of fathers who are being denied a place in their children’s lives. Previously, she worked for Judge Mark J. Lopez in the Domestic Relations Division of the Circuit Court of Cook County, where she researched and drafted the very type of decisions that she now fights for on behalf of clients of the Law Offices of Jeffery M. Leving Ltd. Her experience also includes international law disputes.

Before joining the Leving firm, she gained extensive and sophisticated civil litigation experience, including representing the City of Chicago. She has litigated and supervised law firms for years.

As a new mother and recent immigrant, Summer empathizes with her clients’ struggles and goals, which she has fought for in and out of the courtroom.

Summer earned her Juris Doctor from DePaul University College of Law, Master of Science from Indiana University, and her Bachelor’s degree from Beijing Sports University. She is licensed to practice law in the state of Illinois and the United States District Court of the Northern District in Illinois.

Summer participated in the DePaul Domestic Violence Project to assist domestic violence victims filing petitions for emergency orders of protection. Summer is a past president of DePaul Asian Pacific American Law Students Association, and two-time Diversity Scholarship winner.

Summer has been a fierce advocate for the Asian American community in Chicago.  She has been a regular volunteer at Chinatown Pro Bono Clinic since 2014.  Summer is the communication co-chair of the Asian American Bar Association of Greater Chicago, and a board member of the Chinese American Bar Association.
