Deratany & Kosner

Excellent trial attorney who really knows how to get the maximum recovery on his cases.!

I had an incredible experience working with Deratany & Kosner, and I especially want to recognize attorney Greg Olmstead for his outstanding work. Greg was not only professional and knowledgeable, but also compassionate and genuinely dedicated to getting the best possible outcome for my case. From the start, Greg made sure I understood every step of the process. He always took the time to answer my questions, returned calls promptly, and made me feel like a priority--not just another case. His attention to detail, strategic thinking, and relentless advocacy truly made a difference. Thanks to Greg's hard work and commitment, I felt confident and supported throughout a stressful and emotional situation. I highly recommend Deratany & Kosner, and if you get the chance to work with Greg Olmstead, you can rest assured you're in excellent hands.

He is the best as the business is

Great Lawyers. Mike Kosner is one of the Premier Trial Attorneys in Illinois.

They are complete liars . This is a law firm for abuse and neglect and they know I have a case so they say it’s for injuries … so wack and discriminatory

Was referred to the law firm and attorney Greg Olmstead followed up with me. He was very responsive, so I told other attorneys that I was already moving forward with this firm. After the first call and email, I was ghosted. I just wish the attorney had the decency to send a quick case rejection reply. I sent follow-up emails, as my reference suggested, and I just feel silly for wasting my time and sharing personal information. If you don’t have a lucrative case, don’t waste your time with this firm.

They didn't go to bat for my family on the crestwood water case. They settled for millions & offered us less than $800 total. No amount of money will allow me to live my life after what my family and I have gone through but $800?! That's a slap to the face! Update: my mother passed away due to our case & that's still all we were offered.

Love them from the heart.. They are family... The best law firm ever live...

Great Firm, exceeded my expectations in terms of the outcome of settlement. Special thanks to Jay, Mike and Diedre
