Slide AAHA Proud AAHA is an organization on a mission to certify veterinary practices who demonstrate excellence in medical care. This is a voluntary practice for the hospital, and involves the testing and examination of over 900 facets of running a truly world-class veterinary practice. The standards are uncompromising, which is why fewer than 15% of veterinary practices earn and keep AAHA accreditation. We are proud to be one of the few. Because when it comes to your pet and your family, nothing less than excellence will do.
