Attorney Mark Maciolek represents clients in criminal defense and litigation matters in federal and Wisconsin state courts. Mark’s federal experience includes representing clients charged with complex commercial crimes, federal conspiracy crimes, trade secrets crimes, securities fraud crimes, other white collar crimes, federal firearms crimes, drug offenses, and other areas.

Mark’s state court civil litigation practice includes trial and appellate representation for individuals and corporate clients.
