As a criminal defense attorney at Ramsell and Associates, L.L.C. I have handled literally hundreds of DUIs and criminal offenses of all types. I have fought for my clients by going to trial, and I have negotiated serious charges down to low-level offenses. Prior to the firm, I clerked for the Homicide Task Force at Cook County Public Defender's Office and the DuPage County Public Defender's. I earned a J.D. from The John Marshall Law School, a M.A. from Purdue University Calumet, and a B.A. from The University of Illinois at Chicago. I also served in the U.S. Army for 4 years and in the National Guard for 6. I am currently a member in good standing of the Illinois State Bar Association, the DuPage Bar Association, the Cook County Bar Association, and the National College for DUI Defense.
