In 2003, John Ritter — beloved actor, husband, father, and friend — was taken suddenly due to a tragic misdiagnosis of acute thoracic aortic disease (TAD).

Weeks after his death, his wife and fellow actor Amy Yasbeck founded The John Ritter Foundation for Aortic Health with a focused and urgent purpose to prevent unnecessary suffering because of the unknown.

Every day, we work to raise awareness for TAD through genetic research, widespread education, and radical advocacy.
