AAHA Proud AAHA is an animal health organization with a simple mission: to accredit veterinary practices who demonstrate excellence in everything they do. In order to accomplish this audacious purpose, AAHA routinely examines and inspects participating practices on approximately 900 standards of running a truly exceptional animal hospital - from anesthesia protocols to technology and software, and everything in between. Fewer than 15% of veterinary practices are AAHA accredited. We are proud to be one of the few.
