About me

Robert Callahan has been a successful Chicago defense attorney at law for
over 17 years. We use investigation and thorough preparation to gain an advantage over the prosecution.  When you need legal representation, there is no time
to waste. Consult the law offices of Robert Callahan.  We win more cases because we take fewer clients. This allows us to give individual attention to each file, and the results are proof that our strategy works.
