Mary Margaret Callahan and Abraham

Mary Margaret Callahan is the Chief Mission Officer for Pet Partners, where she is responsible for leading mission delivery, including the Therapy Animal Program and grassroots advocacy program. As an animal lover with a background spanning education and health care, Mary Margaret couldn’t be more delighted to find herself at the nexus of her interests and experience working to improve human health and well-being through the power of the human-animal bond.

The daughter of a veterinarian, Mary Margaret grew up surrounded by pets and has a deep appreciation for the strength of the human-animal bond. She joined Pet Partners in 2013 and has worked to establish the organization as both an influencer and a resource within the animal-assisted intervention (AAI) and human-animal bond (HAB) community. In 2018 she was named one of PetAge Magazine’s Women of Influence.

Mary Margaret lives on a small farm outside Seattle with her husband, daughter, and menagerie of animals including dogs, cats, guinea pigs, chickens, goats, and miniature donkeys.
