About Us

The Name

The Mendota Group is based in Saint Paul, Minnesota suburb of Mendota Heights.  Its location inspired the Group’s name.  But, there”s more to the story. According to local historians, “Mendota” is derived from the Dakota Indian word “Mdote”.  Mdote means “the mouth or junction of one river with another”.  Mendota Heights sits above the confluence of the Minnesota and Mississippi Rivers. Naming the company after a word that means confluence seemed fitting.  The American Heritage Dictionary defines confluence as, “A gathering, flowing, or meeting together at one juncture or point.”  A confluence of ideas refers to a melding of ideas from different sources and perspectives into a cohesive and cogent theme.  That pretty well describes The Mendota Group.
