Charles is an accomplished first-chair trial lawyer who focuses his practice on a range of complex employment and commercial litigation matters, including restrictive covenant, trade secret and other intellectual property litigation, employment and whistleblower litigation, contract litigation and business disputes, fiduciary litigation, and class action defense.

He possesses wide-ranging trial and appellate experience and has appeared in state and federal courts throughout Illinois and across the nation. Charles knows that the willingness and ability to stand up in front of a judge or jury to argue forcefully and effectively for his clients often is the best way to avoid litigation, to resolve it quickly and efficiently when it does occur, and to advance his clients’ interests when full-scale litigation is necessary.

In addition to his courtroom advocacy, Charles is an experienced and trusted business advisor and counselor to his clients, advising them on employment matters, trade secret and other intellectual property protection, and contracting practices. Charles helps his clients address challenges at the intersection of business and law, including by anticipating and preventing problems and avoiding major disputes.

Charles works with a wide variety of clients, ranging from Fortune 500 companies to early growth-stage companies, and he is committed to tailoring each legal strategy to each client’s specific needs and goals.  Charles adeptly partners with executive-level officers as well as the in-house legal staff of his clients, delivering the guidance and counsel they need, when they need it, to navigate their most challenging legal issues.  Charles is dedicated to learning the day-to-day business concerns of his clients and to providing practical strategies in down-to-earth business language.
