Steven Laduzinsky

Steve concentrates his practice in complex commercial litigation, labor/employment issues, professional liability matters, construction litigation, probate matters, fraud investigation and litigation, and election law. Steve has represented individuals, not-for-profit and for-profit organizations and government entities in state and federal trial and appellate courts. He has represented clients’ interests throughout the litigation process, from the initial pleading through motion practice, written discovery, depositions, trial, and appeal. In his 25 year career, he has tried over 100 bench and 30 jury trials to verdict.

Although Steve’s experience has focused on litigation, he has also advised and counseled individuals, small businesses, governmental entities and not-for-profit organizations on reaching practical and creative solutions to problems and disputes without resorting to litigation, including the use of alternative dispute resolution methods. Steve has represented clients in numerous mediations and arbitrations, successfully resolving disputes without a costly bench or jury trial.

Over his career, Steve has developed a niche in handling a wide range of family disputes. The dynamic of the family relationship may prevent a client from fully understanding and realizing the significance and severity of another family member’s misconduct. Family members may intervene to prevent an aggrieved family member from asking questions and receiving information from other family members engaged in misconduct to avoid family conflict. Unfortunately, this often enables another family member to gain financially from the misconduct. Whether the dispute arises from a family business, the distribution of assets after the death of a family member, or a family member serving as an officer, director, administrator, executor, trustee, or power of attorney, Steve has assisted clients in obtaining accurate financial information and protecting their rights in the family business, finding and recovering missing assets, and removing and holding family members accountable for their self-dealing and theft of funds while serving in a position of trust and confidence.

Prior to forming Laduzinsky and Associates, Steve was a named partner in a boutique commercial litigation firm in Chicago, and was a partner in two larger Chicago-based firms. In addition to handling litigation in Illinois’ courts, he has handled litigation in various federal and state courts throughout the country. Steve also serves as of counsel to Kaplan Papadakis & Gournis P.C.

In his spare time, Steve is active in numerous charitable and religious organizations.
