As a small-animal primary care veterinarian, I deal with the diseases of dog and cat...

By Amy Lawton, Research Manager, Chaplaincy Innovation Lab, Brandeis University In times of loss, change or other challenges, chaplains can listen, provide comfort and discuss spiritual needs. These spiritual caregivers can be found working in hospitals, universities, prisons and many other secular settings, serving people of all faiths and those with no faith tradition at all.
