The Radio Rondevoo facility was built in 1940 by the Bobier Company for Florence M. Gardner, owner of KTFI and the Radioland Ballroom. The building held a dance floor and stage downstairs, with offices and a large radio studio upstairs. Every Saturday night throughout World War II, “Live from the KTFI Ballroom” was produced, with big name bands such as Tommy Dorsey, Glenn Miller, Lawrence Welk, and other local bands. In 1950 the facility changed owners and became the Rollerdrome Skating Rink.
For the past several years Radio Rondevoo has been used as an Event Center, hosting Weddings, Quinceañeras, Baptisms, Anniversary parties, concerts, and fundraising events by families from the eight county Magic Valley area.
