Crime Scene & Biohazard Cleanup Near Jolly Corner Seffner, FL

Seffner is an unincorporated census-designated place in Hillsborough County, about 15 miles east of Tampa, with roots that trace back to one of the county's earliest settlements.

The area was originally known as Simmon's Hammock, named for Baptist minister Daniel Simmon, who came from Savannah, Georgia in 1829 to set up a mission near Lake Thonotosassa.

Seffner was named for its first postmaster, F. P. Seffner, and its post office opened in 1884 as the railroad was being planned through the area.

Seffner, Mango, and Dover were the three primary towns along the South Florida Railroad right-of-way between Tampa and Plant City, and each became an important shipping center.

By 1925, Seffner had grown into the fourth-largest town in Hillsborough County, prospering on citrus groves before the devastating freeze of the winter of 1894-1895 had earlier forced many residents to rebuild.

Seffner had a population of 8,362 at the 2020 census, up from 7,579 in 2010, although its ZIP code area, which reaches into Mango and Thonotosassa, is home to around 35,000 people.

In 2013 Seffner made worldwide headlines when a sinkhole opened beneath a home and swallowed resident Jeffrey Bush as he slept in his bedroom; his body was never recovered, and the same sinkhole reopened in 2015 and again a decade later.
