Trundle Consultants Inc. was a consulting firm that conducted surveys and offered business analysis services to clients. Originally founded as Trundle Engineering Company, the firm focused on idustrial engineering management consulting. Clients would hire Trundle to perform studies on their organization or operating methods.

The company was founded in 1919 in Cleveland, Ohio, by engineer, inventor, and business theorist George Thomas Trundle Jr. (1884–1954). Trundle was born in Bakerton, West Virginia, in 1884, the son of George T. Trundle Sr. (1846-1934) and Georgianna Moler Trundle (1852-1929). In 1902, he moved to Cleveland and began his career as an engineer. He worked for the American Multigraph Company, eventually becoming chief engineer before leaving to form his own business.

He was the president of the Trundle Engineering Company until 1953, when his son, Robert C. Trundle (1913-1994) became president. He remained chairman of the board until his death.

Trundle held several patents and wrote articles on business management. He was the recipient of the 1937 Taylor Key award, which is among the highest honors given by the Society for Advancement of Management.

An executive who held several prominent positions at various firms, Donald Richard Meckstroth (1919-2020) became the last owner of Trundle Consultants (1920-1985), with 100 percent ownership. Meckstroth closed Trundle in 1985.
