PROFESSIONAL INTERESTS AND EXPERIENCE
Following graduation, Mario was an Assistant State's Attorney for the Kane County State's Attorney's Office until February, 1991. While at the State's Attorney's Office, Mario tried over two dozen felony jury trials involving charges ranging from murder and sexual assault to lesser felonies.

Mario concentrates his practice in litigation. He has appeared throughout the federal and state courts in Illinois to represent clients on a variety of matters. Primarily, Mario's practice concentrates in personal injury litigation. Mario has been the lead counsel for plaintiffs in toxic tort litigation, medical malpractice litigation, auto injury litigation, premises liability litigation, civil rights litigation, product liability litigation and all other associated areas of personal injury claims. During his career, Mario has handled numerous complex cases involving significant injuries including multi-plaintiff law suits versus Fortune 500 companies.
Mario also engages in a substantial family law practice. He has represented husbands, wives and has been a court-appointed guardian ad litem for children. Mario firmly believes that the role of the attorney in family law is to facilitate an amicable resolution to a difficult situation to ensure that his client's needs are met, while still allowing the client to move forward in life in a positive direction.
Finally, Mario has also represented numerous business clients in both complex and simple litigations concerning contracts, business disputes, and related matters. Mario devotes the same attention to a business dispute irrespective of whether it involves a multi-million dollar contract or a small collection matter-- as he appreciates that business litigation, big or small, may often be critical to the survival of a client's business and livelihood.
