Michael Hersh Korein

About me

I am passionate about representing my clients to the best of my ability and have been doing so successfully for 25 years.  This has won me the recognition of my peers as a Leading Lawyer in Illinois Workers Compensation and rated as one of the Best Lawyers in America.  I have taught numerous continuing legal education courses to other attorneys practicing workers compensation law and have even spoken as a guest lecturer to the Illinois Workers Compensation arbitrators and commissioners as part of their own continuing educational requirements.


In addition, I believe in giving back to the community.  From running free speed and agility clinics to coaching youth sports to my involvement with Youth Lifeline America, I love teaching our children about the importance of self respect, self discipline, and achieving personal success on and off the field.

    Michael is a highly skilled and intelligent advocate for his workers' compensation clients. In this highly compartmentalized area, he is the go-to guy without exception. I have referred numerous workers' comp clients to him, and in addition to obtaining outstanding results for the clients, he is very hands on and willing to keep his clients well informed throughout the process (not many attorneys are willing to do this). Simply put, I know that when referring a client to him, they will be in good hands. I endorse him without reservation.
