The story
The group was founded by 32 successful life insurance agents who met at the Peabody Hotel in Memphis, Tennessee during the annual meeting of the National Association of Life Underwriters (NALU). Their meeting focused on improving technical knowledge and enhancing their sales abilities as well as maintaining ethical standards in the industry, and from the beginning the organization adopted the NALU Code of Ethics. The 1927 meeting resulted in the formation of the MDRT organization.
The group grew quickly, reaching 118 members by 1930 and exceeding 1,000 members by 1952. By 1976 it had 11,804 members and had introduced an elite qualification of "Top of the Table" for members who could show a single year premium production of US$5 million.
