SEMCO History

SEMCO Construction, a family owned and operated business, has a family legacy of hands-on building for more than 45 years. The SEMCO dream began after World War II, when Shelby Earnest Marchant, Sr., or “Daddy Ernie” as his family called him, began in the construction industry as a contractor in Dallas, Texas. His son, Shelby Earnest Marchant, Jr (S.E.), added another dimension to the family business by including new home construction & remodeling. Third generation, Donnie Marchant was welcomed into the business in 1983 and with his father, renamed the company SEMCO Homes in 1993. We changed our name again to SEMCO Construction in 2019.

Donnie moved the business from Dallas to Oklahoma City in 1998, as he saw great potential in the Oklahoma City area. Donnie, wife Debi along with their sons, Josh and Seth continue the dream & are passionate about integrity in all facets of construction & sales.
