Metropolitan Engineering Company was formed by 4 engineers to focus on serving municipalities, water districts, and communities south of St. Louis, MO. The firm grew in projects and staff, and continually got more and more work coming in, serving cities south of the St. Louis area. Word spread that a firm with similar experience and focus was for sale in Hannibal, MO. Before going on a two-week vacation, one of the principal engineers stopped by Hannibal to check it out. After returning from vacation two weeks later, he was told Metropolitan Engineering had purchased the Hannibal firm, Crane & Fleming and on March 4, 1985, the firm currently known as MECO Engineering was born. That principal engineer was asked to run the newly acquired company and promptly picked up his family and relocated to Hannibal, MO.

Crane & Fleming had decades worth of a glowing reputation in the area and nobody in Hannibal, MO had heard of Metropolitan Engineering Company, so the name Crane & Fleming/MECO was used in advertising, promotional items, and marketing. After several years, the company grew, thrived, and was established as a reputable piece of the northeast Missouri community. After more advertising and promotion getting the name change out, the “Crane & Fleming” was removed and the name was changed to MECO Engineering Company, which is where it has proudly stayed for the rest of the now 40 Years in business.
