I am an attorney focusing on overweight truck defense. Since beginning my legal career in 2002 I have worked as a criminal prosecutor, a commercial litigator, a deputy general counsel, and now a private practicioner with my own firm.
In addition to my civilian career, I am also retired Colonel in the United States Army Reserve where I served as a Judge Advocate. I began my military service in R.O.T.C. at John Carroll University. I was commissioned a Second Lieutenant upon graduation from college in 1996 and served on active duty. In 1999, I left active duty to attend law school and joined the Illinois Army National Guard. In 2000, I joined the Army Reserve.
In 2003, I was recalled to active duty and mobilized to the Middle East in support of Operation Enduring Freedom and Operation Iraqi Freedom.
I reside in the suburbs of Chicago and when I am not working I enjoy spending time with family and friends, working out, running, biking, tennis, and fishing.

Incredible
As the addage goes " In a Heartbeat" I originally retained one attorney that wanted to do whatver the prosecutor wanted and actually apologized for bothering the prosecutor with me sitting there watching. I dismissed this attorney and by whatever reason you wish to choose, I found Mr. Sean Connolly. ...
"Sean is a hardworking, knowledgeable, and dedicated attorney. He treats his clients with respect and gives each client personalized treatment."
"Mr. Connolly is a knowledgeable and diligent attorney, providing quality representation to his clients. I endorse this lawyer."
"Sean Connolly's training and experience give him great advantage in the courtroom. Whether he is arguing a case at trial, or negotiating a favorable settlement, Sean is someone I would want on my side to aggressively represent my interests."
