After gaining a license in wireless telegraphy, she sought to honor her ancestor's legacy by establishing a radio school.

It is believed she was well-schooled, with early interests in music and languages (including mastering French, German, and Italian).

Her grandfather was a strong influence in her life – he taught her to use tools and to build mechanical devices and helped develop her interest in science and the new inventions of the industrial age.

There was a family precedent; her cousin, Dr. Mahlon Loomis, had conducted early wireless experiments with moderate success.

Miss Loomis mastered wireless telegraphy, becoming competent enough to be granted a license by the United States Department of Commerce in 1919.

Miss Loomis set high standards for the school, and it attracted students not only from the United States, but Europe and Asia as well.

[8] Miss Loomis was a lecturer, wireless teacher, and author, as well as a member of the prestigious Institute of Radio Engineers.

In addition to a radio laboratory (with equipment constructed almost entirely by Miss Loomis herself), the school maintained a complete shop capable of teaching carpentry, drafting, and basic electricity.

Fewer students could afford the training, and the larger schools like the National Radio Institute had more resources to weather the hard times.

She is known to have relocated to San Francisco in 1938, where the census shows that she lived in the St. Francis Hotel and listed her occupation as a stenographer.

She died in San Francisco on June 7, 1960, at the age of 79, and was buried at the Woodlawn Memorial Park in Colma, California.
