Founded in 1926 as a retail shop called Harry R. Mygrant Glass & Glazing, Mygrant Glass is now a third generation business. It was first passed to son Robert F. Mygrant in 1945, who transitioned the business to wholesale in 1952 and grew it to as many as 6 locations by 1966. Grandson Michael R. Mygrant took over the one remaining location in 1979, and is now general manager of 67 locations nationwide, making Mygrant Glass Co., Inc. the largest independent wholesale distributor of auto glass in the United States.
