Nitschke & Sika is a two-attorney law office established in 1996. Nitschke & Sika S.C. represents clients in all areas of the law. Thomas J. Nitschke (of counsel) and Dainis Sika are both licensed to practice law in Wisconsin and Illinois and various federal courts in both states. Our firm has a casual, informal style, so clients are comfortable dealing with us. In addition, Nitschke & Sika S.C. is different from most law firms or attorneys because we return phone calls and/or messages within 24 hours, if at all possible.
