    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.

    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
