AAHA Accreditation Counts
When quality medical care matters, clients take their pets to AAHA accredited hospitals. There are 3,000 accredited hospitals in North America, and Heart of Chelsea is one of them.

Superior care is clearly a priority for you and your family, so it should be reassuring to know that your hospital made the grade. We continually exceed rigorous reviews that include more than 900 standards created by the American Animal Hospital Association (AAHA) which evaluate quality care and client service.

AAHA accreditation is a trusted sign of excellence. It shows that veterinary professionals are knowledgeable, equipment is well maintained and updated, medical procedures are cutting-edge, and facilities deliver high quality veterinary care.

To maintain accredited status, we voluntarily undergo comprehensive on-site evaluations about every three years. AAHA accreditation keeps us at the front of the veterinary pack. We are dedicated to providing your pet with the best health care possible.

Take pride in the knowledge that your pets are in great hands.
