Tom Heffelfinger has devoted most of his 41-year career to investigating, prosecuting and defending white collar criminal misconduct and violent crime. In addition, he has focused his career upon issues facing Native American communities. Tom has served as an Assistant Hennepin County Attorney, as an Assistant United States Attorney in Minnesota and, on two separate occasions, as the Presidentially-appointed United States Attorney for the State of Minnesota. During Tom’s service as United States Attorney from 2001 to 2006, he also served as Chairman of the United States Department of Justice’s Native American Issues Subcommittee and was responsible for the development and implementation of a wide range of policies related to public safety in Indian Country. In his private practice of more than 27 years, Tom specializes in the representation of individuals and organizations who have been the victims of white collar crime, accused of such crime or are seeking to prevent such crime within their organization. Tom conducts internal and background investigations for such clientele and counsels them in the development of crime prevention programs such as ethics and compliance programs.
