1960's - The Beginning

Sister Anna Marie Meyers has 14 high school students with disabilities about to graduate without job opportunities. She founds The Occupational Training Center as an extension program of Christ Child School in St. Paul, Minnesota. The Training Center amicably separates from the school, appoints John DuRand, Executive Director, and the first Minnesota supported work program begins.


1970's - Developing Concepts

In 1973, manufacturing contracts begin with a large government customer and 3M which remain in place today. Over the next decades these and other business opportunities create hundreds of jobs for people with disabilities. Projects use a mixed workforce of craftsmen and people with disabilities. In 1976, The Occupational Training Center becomes Minnesota Diversified Industries (MDI).

1980's - Gaining Momentum

Electronic assembly capabilities attract new customers growing employment to 600, while a capital campaign raises $2.3 million for building/equipment renovations.

1990's - Years of Growth

Growth continues throughout the decade with the opening of two Northern Minnesota locations – Hibbing (1992) and Grand Rapids (1993). The decade wraps with MDI moving its headquarters to the newly renovated St. Paul facility.

2000's - Changing Times

Employment is at over 400 and the focus is on growing commercial business. In 2004, ground is broke to triple size of the Grand Rapids facility, and MDI receives a three year grant to expand career opportunities for people with disabilities. In March 2008, John DuRand, MDI Founder, passes away, and current President & CEO, Peter McDermott, takes office in August

2010's - From Lows to Highs

The decade starts slow, with no government contract orders, and despite the growth of commercial business, employment drops to 120. But in 2011, a “surge order” and new commercial business expands employment to 440. MDI celebrates the 75th millionth plastic “flat tub”.

2013 - 2014

Deer River Hired Hands is acquired providing daytime training and habilitation for over 50 people with disabilities in the recycling business. Later that year, MDI receives ISO 9001:2008 certification. MDI celebrates 50 years and moves from St. Paul to its current facility in Minneapolis.

MDI Building


In 2016, MDI purchases a building in Cohasset, MN to improve the working conditions for the Hired Hands employees. MDI breaks ground on a new $4.7 million facility in Hibbing and obtains ISO 9001:2015 certification. Product offerings expand to include polypropylene plastic. Services expand in Minneapolis to include medical assembly done in a newly completed “White Room“.



MDI obtains ISO 13485 and FDA registration for medical device assembly.  Brand new $4.5 million facility in Hibbing opens in early 2018.  In 2019, MDI secures a new $2.7m commercial business account for distribution totes. The Quest Transition Program launches, inside MDI Cohasset, for students 18-21 years old with special needs. MDI’s Career Skills reaches 176 graduates and expands outside of MDI.  The team successfully delivers a $2.4 million orders for a new Fortune 500 customer that has tremendous employment impact.

2020 - Present

National pandemic, COVID-19, occurs early in the year. MDI is deemed an ‘essential business’.  Protocols and processes are put in place to ensure a safe work environment. MDI orders decline slightly during Summer 2020. Large government “surge order” occurs in in Q2-Q3 and pushes MDI employment to near 600 employees.
