In his spare time, Blake volunteers as a member of NIU College of Law’s Alumni Council and as a mentor to both law students and recently licensed attorneys. In his capacity as a mentor, he helps to advise and assist prospective and newly licensed attorneys in navigating the legal world and the difficulties new attorneys face.
