Dr. Kathy Shear, Founder and Director of the Center for Complicated Grief, is a an internist and a psychiatrist with the heart of a social worker. She is a talented clinician who has been studying and treating people with complicated grief for more than 30 years.

Complicated Grief Therapy (CGT) has the strongest evidence base of any grief treatment in the world.
