Blood, Trauma, and Biohazard Cleanup in Treynor, IA

Treynor is a small city in Pottawattamie County in southwest Iowa, just east of Council Bluffs.

Treynor began in the late 1880s around Fritz Eyberg's general store, August Olderog's dance hall and saloon, and St. Paul's German Evangelical Church.

Local German immigrant farmers first called the settlement Four Corners or 'High Five,' after a popular card game, and the surrounding area east of Middle Silver Creek had previously been known for its many wolves.

Treynor got its name when its post office opened in the early 1890s, named for the recently deceased postmaster of Council Bluffs; the town was incorporated in 1905.

Treynor got its own railroad in 1911, the Iowa and Omaha Short Line, which ran 12 miles to a Wabash Railroad depot, but the line was unprofitable and quit after only five years.

During the early Cold War, a U.S. Army Air Defense Command Nike Hercules missile base operated just outside Treynor.

Treynor had 1,032 residents at the 2020 census, living in 394 households, crossing the 1,000 mark for the first time.

Treynor packs its population tightly: at about 1,600 people per square mile on just 0.58 square miles, it is far denser than most Iowa towns its size.

Treynor more than doubled in size in a single decade as a Council Bluffs bedroom community, jumping from 472 residents in 1970 to 981 in 1980.

Treynor is a family-heavy town, with a median age of 38.0 years and about 28% of residents under 18 at the 2020 census, and it is served by the Treynor Community School District.
