Grinnell Mutual, a century-old property and casualty insurance and reinsurance firm, unveiled its new brand identity today. The new theme is "Trust in Tomorrow." Along with a new primary logo for Grinnell Mutual, the evolution in brand identity features a new name and logo for its reinsurance unit, Grinnell Re. It also includes a new member logo, Grinnell Mutual Member, which replaces the longstanding FarMutual logo. The new brand identity is Grinnell Mutual's first major update since 1963.
