Our History

Original service station location of Grimsley's


Grimsley's begins as a service station and a Kaiser-Frazier car dealership. The business is a partnership between two brothers, Vernon and John Grimsley.


Kaiser-Frazier stops manufacturing automobiles, leaving the two brothers looking for an alternative product to sell. Through a loose partnership with another individual, Grimsley's begins selling wholesale candy and tobacco products.


After discussion of needs with a third brother, Harold, who owns a floor covering business, Grimsley's Janitorial Supply is formed.


John Grimsley passes away, leaving Vernon as sole proprietor of the business.


Vernon retires from Grimsley's and sells the business to his children, Mark and Jane Grimsley.


Grimsley's Janitorial Supply is incorporated, and becomes Grimsley's Inc.


Mark becomes sole owner of Grimsley's when Jane passes away.

New location of Grimsley's


Grimsley's Inc. moves from its original location on North Main Street to a new 12,000 square foot warehouse located at 119 East Airport Road.


The ownership of Grimsley's changes once again, as Ryan Smith purchases the company from Mark Grimsley. Ryan has worked for Grimsley's since 1994, and will continue to lead Grimsley's in the same upward direction it has taken in the past.
