Introduction
DePaolo & Zadeikis is a Chicago-based law firm dedicated to representing workers and injury victims throughout Illinois. Founded by attorneys Mark DePaolo and Donna Zadeikis, the practice is known for its focus on workers’ compensation and personal injury litigation. With decades of combined experience, the firm has earned a reputation for trial readiness, individualized client care, and consistent success in securing fair compensation.
Unlike high-volume firms that rely heavily on advertising, DePaolo & Zadeikis takes on fewer cases to provide every client with the attention and resources they deserve.

Legal Philosophy
DePaolo & Zadeikis operates with a trial-first philosophy, preparing each case as though it will go before a jury. This strategy ensures that opposing parties take claims seriously and increases the likelihood of favorable outcomes.
The firm works on a contingency fee basis, meaning clients pay no legal fees unless compensation is secured. By handling a smaller number of cases at a time, the attorneys are able to devote greater resources to each matter. Clients receive direct communication from their lawyers, timely updates, and clear, honest assessments of their claims.
Recognition
Both founding partners have received professional recognition for their contributions to Illinois law. Mark DePaolo has served as president of the Workers’ Compensation Lawyers Association and has been named to Super Lawyers multiple times. Donna Zadeikis is equally respected for her trial advocacy and commitment to injured clients. Together, they have established a firm respected by peers, clients, and the courts for professionalism and results.
Client Experience

The firm is praised for maintaining close communication, returning calls promptly, and making clients feel heard and supported throughout their cases. Many clients emphasize that they were treated as individuals, not case numbers, and that the attorneys fought tirelessly for their rights.
