Established in 1897, The Brethren Mutual Insurance Company is owned by its policyholders, rather than stockholders. Brethren Mutual is a property/casualty insurance carrier with a stable foundation. Brethren Mutual is extremely proud of its heritage, as well as, its niche in the insurance marketplace. We have grown from a small insurance organization that protected local farm dwellings, crops and personal belongings, to a regional company currently servicing the personal, business and farm insurance needs of policyholders in Maryland, Pennsylvania, Virginia, and Delaware as well as the commercial needs of policyholders in the District of Columbia.
