Nutri-Systems Inc. was started in 1969 by Gary Frame, Lee Larsen, and Milo Martin.  It was one of the first independent Animal Nutrition Consulting Firms to be established in California.  The company initially provided services to the larger milling companies and later specialized into beef and dairy nutrition and management consulting.  In 1979 Nutri-Systems Inc. hired Tim Riordan as one of its consultants.  Tim worked together with Gary, Lee, and other staff consultants.  In the late 1990’s both Gary and Lee retired and named Tim Riordan the sole owner of Nutri-Systems Inc. Tim ran the company by himself for a number of years until 2008 when his son Andy decide to become part of the family business. Together with years of industry, feed and technological experience has made Nutri-Systems one of the leading cattle nutritional firms in California.
