The Home Depot is the world's largest home improvement specialty retailer, with stores in all 50 states, the District of Columbia, Puerto Rico, U.S. Virgin Islands, Guam, 10 Canadian provinces, and Mexico. The Home Depot was founded in 1978 by Bernie Marcus and Arthur Blank. Along with investment banker Ken Langone and merchandising guru Pat Farrah, the founders’ vision of one-stop shopping for the do-it-yourselfer came to fruition when they opened the first two Home Depot stores on June 22, 1979, in Atlanta, Georgia. According to Bernie and Arthur, the customer has a bill of rights at The Home Depot, and this entitles the customer to the right assortment, quantities and price, along with trained associates on the sales floor who want to take care of customers.
