John is a native of Joliet, Illinois, and a lifelong resident of Will County, where he has practiced law since 1993.  He has over 25 years experience in the areas of real estate, personal injury, workers’ compensation, criminal and traffic, family law and probate.

John worked for a local law firm upon graduation from law school, but struck out on his own in 1998.  He began his solo practice in 1998 in Joliet and continued running his own practice until joining Kavanagh Grumley & Gorbold, LLC.  In 2019, his solo firm was voted one of the best law firms in Will County in the Herald-News Readers’ Choice Awards.  Kavanagh Grumley & Gorbold LLC was voted the best law firm in the same poll.  Merging his solo firm into KG&G allows John to continue in the path of excellent legal services.
