Every law firm's resume speaks of the unwavering commitment of its lawyers to advance the clients' interests in an intelligent, efficient, and economical way.  That was the basis upon which Ottosen DiNolfo Hasenbalg & Castaldo, Ltd. was formed in 1992, and that remains the cornerstone of the firm today.  What sets Ottosen DiNolfo apart is the fact that many of its lawyers are distinguished, not only as lawyers, but also in other fields.

Karl R. Ottosen started out of law school with the Illinois State Labor Relations Board as one of its first hearing officers. As such he helped shape policies that govern the Board's operations even today.  Stephen H. DiNolfo began his career as a Cook County Assistant State's Attorney and handled hundreds of jury and bench trials.  Maureen Anichini Lemon serves as an adjunct law professor which brings an understanding of educational systems to her role as counsel to the clients she serves.

Many of the firm's attorneys are frequently invited to speak to various professional groups, provide training, as well as write for various professional journals and publications.
