DiTommaso Law, LLC is Built on Business Litigation

We come into the picture when the stakes are high, because we “dare mighty things, to win glorious triumphs,” as Theodore Roosevelt put it.

DiTommaso Law, LLC focuses on the litigation needs of our individual, small business and large corporate clients. Our lawyers are at home executing complex business litigation in the heat of the courtroom.

We navigate the judicial system with fast, flexible and prudent skill as only an experienced litigation-focused firm can. From depositions, and briefs to courtroom presentation, our Chicago business litigation attorneys execute every step with committed diligence.

The outcome is results. Along with co-counsel, DiTommaso Law, LLC secured a $40,000,000 settlement in the class action lawsuit of Erikson v. Ameritech. The settlement was the second largest in the state of Illinois that year according to Crain’s Chicago Business. The DuPage Bar Legal Assistance Foundation has dubbed us Law Firm of the Year, citing our “commitment to the ideals of the legal profession.” Learn more about our record.

The same hard-work philosophy that led Vincent DiTommaso and Peter Lubin to found their firm extends to contributing to the legal community. Both partners teach trial and litigation skills to law students at University of Chicago’s prestigious law school. That dedication drives them to provide the very best representation for every client, large or small.
