History of 314 S. Sixth Avenue - The Whitmore House

The building at 314 S. Sixth Avenue was built in 1906 for Dr. W.V. Whitmore. He was born in 1862 in Maine. He received his medical degree from the University of California and moved to Tucson in the 1890’s to take a position as a physician for the Southern Pacific Railroad. He soon entered private practice and quickly became a prominent physician and very active community member. Whitmore helped found the Pima Medical Society and served as its president of the Arizona State Medical Association.


Somehow appropriate for the current use of his home, Dr. Whitmore was indicted in 1924 for narcotics violations. He was convicted of conspiring with Tito Flores, a druggist with pharmacies in Tucson and Bisbee. The criminal case’s trial evidence showed that during the period of the conspiracy, Dr. Whitmore wrote 3,500 prescriptions for narcotics, often without even seeing the patient, all of which were filled at the Flores pharmacies. Whitmore’s friend of 25 years, U.S. District Judge W.H. Sawtelle, had tears in his eyes as he sentenced Whitmore to 15 months at McNeil Island, Washington. 

Dr. Whitmore returned to Tucson and lived in his house until his death in 1940. His wife had died just months earlier.

The Whitmore House was acquired by a barber named H.W. Sprawls and eventually became the Park Barber Shop, which continued to exist until at least 1971. By 1981, the property was vacant. In 1990, it housed the Community Outreach Program.
