Outstanding Asst. State's Attorney

Mary Cole
Lake County Assistant State’s Attorney
Lake County Court House

Mary Cole
In 2013, Mary received her Undergraduate Degree in Paralegal Studies from Southern Illinois University. During this time, Mary served as a Domestic Violence Victim’s Advocate for the Williamson County State’s Attorney’s Office.  After three and a half years as a Victim Advocate, she returned home to Lake County. She worked at the Cook County State’s Attorney’s Office from 2015 – 2016 in the Special Prosecution Bureau Gang Crimes Unit and the Domestic Violence Unit. Mary graduated from John Marshall Law School in 2016 and began working as an Assistant Public Defender in Dekalb County.  Since 2018, Mary has worked at the Lake County State’s Attorney’s Office in the traffic and misdemeanor division.  

Mary quickly gained the respect of many in Lake County by her professionalism, calm demeanor, and genuine dedication.  Mary is a diligent but fair prosecutor who believes that “one-sided compassion is just as dangerous as no compassion.”  

Mary Cole deserves this recognition for her hard work; she is an asset to the Lake County State’s Attorney’s office.  Our community and our streets are safer because of her. 

Congratulations from AAIM’s Court Monitors!

Desirée Sierens is an Assistant State’s Attorney in Boone County, Illinois, where she primarily prosecutes felony offenses under the Illinois Vehicle Code.  Desirée graduated from the University of Illinois in 2002 and graduated Cum Laude from Northern Illinois University College of Law in 2006, where she was Managing Editor of Law Review.  In 2006, Desirée started her career as a misdemeanor and traffic prosecutor in Boone County, Illinois.  She left for a brief period of time to prosecute in Winnebago County, Illinois but returned to Boone County in 2016.  Desirée has prosecuted a wide variety of crimes throughout her career, from ordinances to murder, but her passion is prosecuting felony traffic offenses.  In so many of those cases, peoples’ lives are turned upside down due to the selfish decisions of those who drive while impaired. She is honored to work with victims, their families, advocates, law enforcement, and fellow members of the Boone County State’s Attorney’s Office in bringing justice to impaired drivers.   

We are proud to recognize Desirée with the Outstanding Assistant State’s Attorney Award.
