Attorney Profile

As founder of John DeLeon & Associates, John R. DeLeon is dedicated to representing the rights of people in Chicago, Illinois, and throughout the surrounding area. He focuses his practice on handling cases that involve criminal defense matters and civil rights violations.

Mr. DeLeon earned his law degree from the DePaul University College of Law.

An arrest alone can cause a host of problems for the accused. Having even a slight blemish on a criminal record can prevent someone from finding decent housing or meaningful employment. Misdemeanor and felony convictions carry even more implications, resulting in an array of consequences such as jail time, fines and loss of driving privileges.

Having four decades of experience as an attorney has given Mr. DeLeon the litigation skills necessary for successfully defending a client. He understands every aspect of criminal proceedings, from the procedures law enforcement members are required to follow during an arrest, to the trial to an appeal. Taking an aggressive approach to defense, Mr. DeLeon has built a track record of getting charges reduced or dismissed and securing minimized sentences.

A solid defense requires legal savvy and outside-the-box thinking. Mr. DeLeon is adept at recreating the scene of a crime to poke holes in the prosecutor’s argument. He uses expert testimony and eyewitness accounts to uphold his client’s position. Mr. DeLeon is committed to securing the best possible outcome for people facing criminal charges.
