According to a book recounting the history of some of Sheridan's historic homes, the house at 148 S. Brooks was built in 1906 for the Mills family.
This most likely was the family of Robert J. Mills, who received the original deed to the land in March 1889, from the “corporate authorities of Sheridan.” The deed granted all of lots 15 and 16 in Sheridan Original Town Block 20.
A year after the house was built, the property was purchased by a “Mr. Telander” and his wife, Mable Coffeen Telander. The home stayed in the family for several decades. In 1982, the date the historic homes book was published, the property was owned by the Telanders' daughter, Mrs. George Ewan. County Attorney Matt Redle said George Ewan was a long-time dentist in the city. He said the house had also seen use as an apartment building.
In the 1982 book, the address of the property was given as 130 S. Brooks.
Sheridan physician Michael Strahan bought the building in 1998, according to county records. He added an addition to the back of the structure to provide more medical space. Records show the county bought the building in January 2007, and remodeled the interior to provide offices for the county attorney and his staff.
