  • Matthew Joseph Medina

    I endorse this lawyer. I first encountered John when I was an Assistant Cook County Prosecutor. He was opposing counsel on many of my cases. John is was of the best defense attorneys I know. He is a tough-as-nails defense attorney, yet, he never alienated opposing counsel or the judge. He is well respected and that respect is well deserved.
