Part of Early Caldwell Settlement…
The Frost-Dorman Property

Elijah and Matilda Frost

Elijah Frost led five different wagon trains along the Oregon Trail 1847-1862. He and wife Matilda settled in Caldwell near the future Chapter House site in 1883.



Idaho "Ida" Frost Dorman was born in 1871 in Idaho Territory. Henry Dorman came to Idaho in 1883, prospecting for gold. He came to Caldwell in 1885, and married Ida in 1893. They raised prizewinning fruit and cattle.

Dorman Mansion

The Dorman Mansion (their second house) was built in 1910 for $10,000. The Caldwell newspaper carried several articles on its construction, stating: "The house will be modern throughout, and it is safe to say that it will be one of the finest houses in the city…."


Providing Community Health Care…
The Caldwell Sanitarium

Caldwell Sanitarium

In 1919, the Dorman house was purchased by three physicians--Doctors Fern Cole, James A. Young, and Clifford Kaley. The doctors converted it into a private hospital, called "The Caldwell Sanitarium." They retained much of its home-like atmosphere to help patients feel more comfortable.

Dr. Fern Cole

Dr. Fern Cole delivered many babies in the Sanitarium. He and Dr. Clifford Kaley, with the help of Judge Thomas Buckner and Charles Tobias (all of their wives were all PEO members), donated the building for use as a retirement home for members of the P.E.O. Sisterhood.

The P.E.O. Chapter House Dedication, 1951

The formation of a Chapter House (retirement home) was first discussed at a 1936 P.E.O. State Convention. The onset of World War II disrupted such plans. In 1950, the former Caldwell Sanitarium was donated to the cause. An extensive renovation project restored the mansion into like-new condition. Idaho was the fourth state to have a P.E.O. home.
