William Clark attended Loyola University of Chicago on a swimming/water polo athletic scholarship and was elected as the president of his fraternity.  William obtained his undergraduate degree in history, then worked as a teacher and varsity swim coach at Marist High School and later St. Benedict High School for several years.  After attending law school at night, he graduated from DePaul University with a Juris Doctor degree and has been a licensed attorney in Illinois since 1977.  Before founding his own practice, William worked his way up from an associate attorney to become a partner at Dore & Clark where he extensively litigated cases in the Circuit Court of Cook County; and has argued cases before the United States Supreme Court, the Illinois Appellate Court and Illinois Supreme Court.

As he began to focus solely on family law and divorce litigation, William founded, and is the principal attorney, for William G. Clark, Jr. & Associates, Ltd. where he is able to put his extensive litigation experience into practice on behalf of his clients.  William is a Fellow in the American Academy of Matrimonial Lawyers and has represented a variety of clients with their financial and parenting issues.

William continued to put his experience to work as a speaker at the Chicago Bar Association and the Illinois Institute for Continuing Legal Education.  He has been a volunteer for the Chicago Volunteer Legal Service earing a “Distinguished Service Award” for his pro bono work representing individuals in dissolution of marriage and other family law matters who were unable to afford private counsel.

William’s ties to Chicago and political heritage can be traced back more than 100 years. Mr. Clark’s great grandfather served as a Chicago alderman for many years beginning in 1909. His grandfather, John S. Clark was the Cook County Assessor from 1934-1954. Mr. Clark’s father, William G. Clark held numerous elected offices in Illinois including State Representative; State Senator; Attorney General; and the Illinois Supreme Court where he served as Chief Justice from 1985-1988.

In his spare time, William enjoys spending time with his family, fishing, and spending time outdoors in the Upper Peninsula of Michigan.
