40 Years of Excellence AAHA is an organization that accredits veterinary practices for upholding a simple standard: excellence in everything you do. A practice must undergo continuous inspection and testing in over 900 facets of care, from anesthesia protocols to internal operations, in order to earn and keep accreditation. Because of the rigorous standards, fewer than 15% of practices in the nation are AAHA accredited. We are proud to celebrate our 40th anniversary of AAHA accreditation. AAHA's pioneering spirit and uncompromising standards have been a powerful guiding force for our continuous improvement.
