Joseph received his Bachelor’s Degree in 1986 from Lake Forest College and his Juris Doctor/Master of Business Administration in a joint degree program from Dominican University and The John Marshall Law School in 1993.

Joseph was immediately hired by a prestigious defense firm in Chicago where he concentrated on defending employers and their insurance companies in major loss workers’ compensation cases throughout Illinois. The firm partners recognized his abilities from the onset and trusted Joseph to oversee high-profile workers’ compensation cases for major clientele.

Other clientele took immediate notice of his trial results as well. At the specific request of a team of Illinois risk managers of a major client, Joseph formally divested himself of all other firm responsibilities and became their designated attorney to exclusively handle their sizable Illinois workers’ compensation caseload. He was even asked to oversee their workers’ compensation cases in other states as general counsel only 3 years after his graduation.


In 1998, after five years defending insurance companies and employers, Joseph decided he would rather champion the rights of the injured rather than seek to limit them. In 1998 he joined his brother Andrew Leonard in developing and promoting Employee Legal Services, LLC. into a prominent workers' compensation/personal injury plaintiff’s firm that Andrew had started with the assistance and vision of their late father Dr. Eugene Thomas Leonard III. The firm is now known as Leonard Law Group, LLC with Joseph as the firm’s senior attorney and is located at Teamster City in Chicago, Illinois.


Joseph specializes in difficult career ending worker’s compensation claims and permanent total disability claims. He accepts cases that other attorneys have rejected as “unwinnable” and consistently shows otherwise. Joseph has represented thousands of union and nonunion workers and has successfully argued and won cases before the Illinois Workers' Compensation Commission, Illinois Circuit Court and Illinois Appellate Court. Joseph has a 98% success rate on workers' compensation claims he has taken to trial and is recognized by his peers as one of the best and most knowledgeable workers’ compensation lawyers in the State of Illinois.


It is with this same zealousness that Joseph represents his personal injury clients. Joseph concentrates his personal injury practice in the area of construction site accidents; representing carpenters, ironworkers, laborers, and all tradesmen and women.

Joseph also represents those injured in scaffolding accidents, crane accidents, trucking accidentscar accidents, bus accidents, medical malpractice and premise liability. Joseph is currently in the pre-trial discovery process on numerous severe construction site accidents and trucking accidents.



After graduating from Lake Forest College in 1986 with his Bachelor’s Degree, Attorney Joseph Leonard obtained his Master of Business Administration and Juris Doctor Degree from The John Marshall Law School in 1993.
