I was referred to Jay Paul Deratany by a friend after my son was born with a severe birth injury causing cerebral palsy. His firm was very compassionate and helped with my medical malpractice case. Thanks to Deratany, I not only received significant compensation for my family, but he also taught me about the law and guided me through each step of my case. I would strongly recommend Chicago personal injury attorney Jay Paul Deratany and The Deratany Firm to anyone looking for highly experienced and competent lawyers who are knowledgeable, especially in the area of personal injury and medical malpractice law.
