1948 - 1952
Staff records was run by distributor Idessa Malone in Detroit, Michigan, U.S.. Billboard says she left the running of the label to newly found partners in late 1948 opening her own Dessa label, but still with a financial interest in Staff.
By October 1949, after disagreements with her partners, she dumped the Dessa label (Decca hadn't been too happy with the name) and became full owner of Staff again.
In September 1952 she was mentioned as "former owner of Staff Records" and was then contemplating opening a label for religious recordings, "Divine Recording Services".
