John Miller Carroll Attorney At Law
Before starting law school, I learned about Abraham Lincoln’s impactful work as a trial lawyer. I admired his excellence and I wanted to pursue a career in which I could also make a difference. Becoming a criminal defense and personal injury attorney has allowed me to do this. I believe that everyone deserves proper representation when they have been accused of a crime or have been injured due to negligent actions of others. Throughout my three-decades-long career, I have advocated for those who need it most and fought for the rights of my fellow Wisconsinites with pride in Appleton and beyond.
