The State of Ohio chartered The National Mutual Automobile Association. The company could write only automobile fire insurance, and its first association members were twenty residents of Celina, Ohio.

1915

The association had its first fire loss - an auto was destroyed in a paint shop. Business was handled out of a two-room office with only one clerk. Mr. Brookhart described the early days thus: "Of necessity I was publicity manager, home office underwriter, field man, loss man, mail boy, and office janitor, in addition to trying to take care of a local insurance agency here in Celina."
