I am a graduate of the University of Illinois, Urbana-Champaign with a Bachelor of Arts in Political Science and a minor in Spanish. I then attended DePaul University College of Law and earned a Juris Doctor.

While in college and law school, I worked for the Lake County Planning Department, assisting the county planners in the future plans for Lake County, Illinois. During law school, I performed an externship at the United States Attorneys’ Office in Chicago where I prosecuted petty offenses and assisted in the prosecution of federal crimes. I also served pursuant to Supreme Court Rule 711 while in law school with the Lake County State’s Attorney’s Office Criminal Division where I prosecuted traffic and ordinance violations and misdemeanor offenses as well as in the Civil Division.

After graduation from law school, I worked as an associate with the law offices of Block and Block in Chicago, Illinois, where my practice was primarily in the area of family law.

I was also the assistant Village Prosecutor for the Village of Wheeling, Illinois. As the Prosecutor, I appeared in court to prosecute all the traffic and ordinance violations and various misdemeanor charges on behalf of the Village of Wheeling. I prosecuted numerous driving under the influence of alcohol and/or drug (DUI) cases as well as driving while suspended or revoked, theft, retail theft, battery and various other criminal offenses.

From 1995 to 2011, I worked as a contractual Hearing Representative, and from 1996 to 2011, as Hearing Officer for the Illinois Secretary of State, Administrative Hearings Department.
