The AO VET community embodies a culture of teaching and learning, combined with research and development. As the only worldwide academic community in veterinary medicine that delivers innovative educational and research opportunities, AO VET created a membership to give veterinarians a core group of individuals with whom to communicate, not only to solve clinical problems, but also to enhance their training and career. After attending an AO VET educational event, becoming a member is the means to joining the AO VET family and sharing our passion for veterinary surgery.

The first undertaking of the AO founders—Maurice E Müller, Robert Schneider, Hans Willenegger, Martin Allgöwer, and Walter Bandi—was to find a suitable place to conduct research.
