he Mid-Atlantic Petroleum Distributors' Association is an organization of independent marketers of branded and unbranded petroleum products. Together with members from a broad range of supporting industries, MAPDA distributors have played a key role in bringing about the advancement of the petroleum industry throughout the region and beyond.

Dating back to 1946, and evolving through several name changes along the way, MAPDA has become a strong and respected trade association that provides numerous services and education for its members. Its unified voice has become a respected clarion among legislators, government officials, industry leaders, and representatives of the business community.

MAPDA members are located throughout the mid-Atlantic region and distribute fully ninety percent of the residential heating oil sold in all of Maryland. MAPDA members distribute more than one-third of all the gasoline sold in Maryland as well, and most MAPDA member companies are privately held and operated by second-, third-, even fourth-generation family members who are active in a wide variety of civic groups, community organizations and state and local politics.
