Established in 1878, the Louisiana Dental Association (LDA) is the largest professional health organization for dentists in Louisiana. It is a statewide grassroots organization whose purpose is to promote, advocate, and protect the dental professional. The LDA is made up of nine component societies covering each major area of the state. Each holds organized meetings, special events and seminars. The LDA promotes your services, represents your needs and provides support services and continuing education events on a state level, while the ADA provides similar services on the national level.
