Lily McArn
Therapy Dog

Lily visits the Center on Tuesdays. She is a black lab mix who came to live with College Chaplain Jeff McArn after being placed in a rescue facility. Lily’s interests focus on outdoor recreation, particularly involving squirrel life, but if a rabbit or ground hog are available, they produce a special quiver in her heart. She loves long walks on cross-country trails in the summer and golf course sprints in the winter where deer wander. While pictured above with her book Inside of a Dog, Lily cannot in fact read, but she is a solid couch potato, able to sit through multiple conversations and movie viewings at a stretch. In December, 2015, she drove to Tonowanda, NY for her certification exam to become a therapy dog. She passed her 13-point exam with flying colors and proudly wears her official insignia when she is at work. She has made official therapy visits to Community Memorial Hospital in Hamilton, NY and the Presbyterian Home in New Hartford, NY and is primed and ready to sit with students who desire her company in therapy sessions in the Counseling Center at Hamilton College.
