Acadian Ambulance is one of the largest ambulance services in the nation, offering emergency and non-emergency transportation to areas in Louisiana, Texas and Mississippi. In 1971, Acadian Ambulance began operations in response to a sudden crisis. Communities around the country found themselves without emergency medical transportation when new federal regulations caused funeral homes to discontinue using their hearses for emergency transport. These regulations went into effect at midnight on September 1, 1971. At 12:01 a.m., Acadian Ambulance began its Louisiana operations with three young co-founders, two ambulances, eight medics, and the parish of Lafayette.
