About me

Attorney Colleen Thomas is a dedicated legal advocate for clients throughout McHenry County and Kane County in Illinois. She received her law degree from Northern Illinois University, where she was the Assistant Managing Editor of the Law Review, as well as the recipient of numerous accolades for her work in the International Moot Court Competition.


During law school, Ms. Thomas also gained invaluable experience as a law clerk in the Kane County Judges Office and at a prestigious firm in the city of Chicago. After passing the Bar in 1994, Ms. Thomas worked in civil litigation and appeals before opening the doors of Thomas Law Office in 1996. Her well-rounded experience in various areas of civil law, family law and bankruptcy law give her a unique skill set that is perfectly suited for family law cases, which often involve both domestic and financial matters.
