Testimonials

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 & Kosner, 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 Deratany & Kosner to anyone looking for highly experienced and competent lawyers, especially in the area of personal injury and medical malpractice law.

- JOHN C.

I brought a case to Mike and Jay a couple of years ago. No police report or solid record of the injury. In spite of tough facts they got an incredible result and a very high settlement! Professional and responsive at every turn, and not afraid to go to trial if they need to. These guys are the real deal!

- DANIEL M.

Working with Jay Deratany has been an absolute pleasure. If you’re looking for a Personal Injury Attorney, a medical malpractice attorney, or a car accident attorney in Chicago… I HIGHLY recommend them!
