History of Main Street America Insurance
- Founded: 1923
- Founders: National Grange Mutual Liability Company (Grange Fraternity members)
- Acquired by American Family Insurance Mutual Holding Company: 2018
The company was organized in Keene, New Hampshire, on March 28, 1923, as National Grange Mutual Liability Company, and began doing business on July 16 of that year. Its founders served members of the Grange Fraternity, the farmers' organization, offering affordable coverage to a membership that commercial insurers often bypassed. A companion carrier, National Grange Fire Insurance Company, formed in 1935 and was later absorbed into the mutual.
The modern structure assembled gradually through mergers. In 1959, National Grange Mutual's subsidiaries consolidated into Grange Mutual Insurance Company. The Main Street America Group organization was initiated in 1986, acquiring 100 percent of NGM's common stock and beginning the conversion of the old mutual into a stock insurance company under a holding structure. In 1996, the group merged with Mutual Assurance Company, adding Old Dominion Insurance Company to the portfolio.
Between 2003 and 2005, the company adopted the Main Street America name and moved its headquarters and domicile from Keene to Jacksonville, Florida, repositioning itself as a national carrier rather than a regional New England mutual. Acquisition and affiliation continued: the group acquired Great Lakes Casualty Insurance Company of Grand Rapids, Michigan, in 2008, and between 2009 and 2012 affiliated with Grain Dealers Mutual of Indianapolis, Spring Valley Mutual of Minnesota, and Austin Mutual Insurance Company of Maple Grove, Minnesota.
By the late 2010s, Main Street America wrote more than $1 billion in annual premium across personal and commercial lines through roughly 3,000 independent agents. Its mutual holding structure made it a natural partner for a larger mutual. In May 2018, the group announced a merger with American Family Insurance; the combination completed later that year. The rationale on both sides was channel and geography: American Family sold through exclusive agents, Main Street America through independent ones, and their books were largely non-overlapping.

Inside American Family, the subsidiary kept its name, its Jacksonville headquarters, and its independent agent distribution. The 2023 to 2025 hard market hit commercial and personal books hard, and in 2025 the group exited Main Street America's personal lines business entirely, refocusing the century-old brand on commercial insurance and farm and ranch coverage. The company marked its 100th anniversary in March 2023 with commemorations in Keene and Jacksonville.
About American Family Insurance Mutual Holding Company
What does American Family Insurance own?

Who founded American Family Insurance?
Herman Wittwer founded the company in Madison, Wisconsin, on October 3, 1927, as Farmers Mutual Automobile Insurance Company. His founding insight was that farmers presented lower auto insurance risk than city drivers and could be served more cheaply by a dedicated mutual insurer. The company renamed itself American Family Mutual Insurance Company in 1963.
Where is American Family Insurance headquartered?

American Family Insurance is headquartered at 6000 American Parkway in Madison, Wisconsin, where it has been based since its 1927 founding. Subsidiary operations are based in Boston for Homesite, Jacksonville for Main Street America, and Nashville historically for The General before its 2024 sale.
How many brands does American Family Insurance own?
The group operates approximately four primary consumer-facing brands: American Family, Homesite, Main Street America Insurance, and CONNECT powered by American Family Insurance. Including supporting entities such as Bold Penguin, Midvale Indemnity, and American Family Life Insurance Company, the broader corporate family comprises more than a dozen licensed insurance and service companies.

Main Street America Insurance Categories & Tags
Awards & Recognition
Main Street America holds an A (Excellent) financial strength rating from AM Best with a stable outlook, the rating agency's third-highest grade, and an "a+" issuer credit rating. These ratings are the primary third-party recognition that matters in commercial insurance distribution, since independent agents typically will not place business with carriers below A-level ratings.

The brand also maintains affiliation with Trusted Choice, the branding and referral program of the Independent Insurance Agents and Brokers of America, a relationship it retained through the American Family merger and continues to market in agent communications.
Main Street America Insurance Recalls & Controversies
Main Street America's most significant recent scrutiny followed its parent's 2025 decision to exit the subsidiary's personal lines business. The withdrawal left independent agents and their customers needing replacement coverage for home and auto policies, generating complaints typical of market exits and requiring regulatory filings in affected states. The company attributed the move to underwriting performance within the group's broader restructuring after three record catastrophe-loss years.
The 2018 mutual merger itself was uncontroversial: both companies were mutuals, policyholder-members of each voted in favor, and regulators in Wisconsin and Florida approved the combination without condition.
No major fraud finding, accounting restatement, or enforcement action is on record against Main Street America or its underwriting companies as of November 2026.
