American Animal Hospital Association

The American Animal Hospital Association (AAHA) is a non-profit organization for companion animal veterinary hospitals. Established in 1933, the association is the only accrediting body for small animal hospitals in the U.S. and Canada. The association develops standards for veterinary business practices, publications, and educational programs. Any veterinary hospital can join AAHA as a member, but must then pass an evaluation in order to receive AAHA accreditation. Provided by Wikipedia
