What it Means AAHA is an organization on a mission to accredit veterinary practices who uphold a simple standard: excellence in everything you do. In order to earn accreditation, a practice is evaluated on approximately 900 criteria of running a truly exceptional veterinary practice. Because of the stringent and advanced standards, fewer than 15% of veterinary practices earn accreditation. We are proud to be one of the first practices in Memphis to earn accreditation. Because when it comes to your pet, we believe you deserve no less.
