Judge Tiffany Davis is a McHenry County Circuit Judge and former career prosecutor. She was sworn in as Circuit Judge of the 22nd Judicial Circuit in 2017 after being appointed by the Illinois Supreme Court. Prior to being appointed judge, she served as a prosecutor for over twenty-two years.

Judge Davis began her career in 1994 as an Assistant State’s Attorney with the Winnebago County State’s Attorney’s Office in Rockford. Then, after a brief stint as a Civil Litigation Associate in DuPage County, she joined the McHenry County State’s Attorney’s Office, where she served for a decade. She then rejoined the Winnebago County State’s Attorney’s Office, where she served as first chair for the felony division, supervising a general felony caseload of over three hundred felonies.

In her extensive career as a prosecutor covering three counties, Judge Davis prosecuted thousands of cases and tried over forty-five jury trials, including fifteen murder trials. She has prosecuted every type of crime, including murders, arsons, sex offenses, weapons offenses, narcotics trafficking, DUIs, home invasions, armed robberies, and property crimes. As the only career prosecutor currently serving on the bench in McHenry County, Judge Davis brings a necessary background and experience to the courts.

Judge Davis also teaches criminal law and criminal procedure at McHenry County College, where she serves as Adjunct Instructor in Criminal Justice. Since 2004, she has taught students who wish to become police officers, laboratory personnel, and correctional officers. Judge Davis was admitted to the Illinois Bar in 1994 and the Illinois Capital Litigation Trial Bar in 2005. She is a member of the Women’s Bar Association, Illinois Bar Association, National District Attorneys Association, Prosecutors Bar Association, and McHenry County Bar Association.

It was love for her sister that prompted Judge Davis’ interest in the law. She wanted to help her sister, who had found herself in difficult situations. Then, in 1999, her sister was tragically killed through an act of domestic violence. This tragedy drove Judge Davis to a career as a prosecutor of violent crimes, and now as a judge working to ensure justice for all.

Judge Davis is the first person in her family to be interested in the law. When she graduated Cum Laude from the University of Illinois in 1991, her graduation robe was a black robe, and she knew then without a shadow of a doubt that she wanted to one day serve as a judge. She went on to earn her law degree from Southern Illinois University in 1994. While in school, she interned in the St Clair County Public Defender’s office and volunteered in the SIU legal clinic, where she assisted elderly clients with wills and powers of attorney and coal miners with the preparation and filing of black lung claims.

Her parents are her inspiration. Judge Davis’ father was in the Air Force, so she grew up on and near air force bases across the country. He taught her the importance of service to country and community, especially when, while in his retirement in his 60s, he signed up to serve as a Supervisor at TSA after 9/11. Judge Davis’ parents worked tirelessly to put her through college, with her father becoming a car salesman after retirement and her mother opening a beauty salon. They encouraged her pursuit of a legal career, even giving her a custom-made gavel upon her graduation from law school. At her recent judicial swearing in, they got to give her a new gavel, this one with the inscription “Circuit Judge.”

Judge Davis is a 20-year-resident of McHenry County, living in Woodstock with her family. Her husband, Dan, is a former McHenry County Assistant State’s Attorney who graduated from the US Military Academy at West Point. They have three children: Daniel, Bryce, and Anna. They adopted Daniel, Judge Davis’ nephew, when he was eighteen months old after her sister’s tragic death. Their twins, Bryce and Anna, were born prematurely at 27 weeks, leading to her family being an Ambassador Family for the March of Dimes in 2008. All three children have attended District 200 public schools. The family attends St Mary’s Catholic Church in Woodstock. Judge Davis is a member of the Sun City – Huntley Lions Club, and during her free time she likes to stay active by walking and traveling.
