Former KGO-AM 810 anchor Mary Ellen Geist, who left radio in 2005 to become a caregiver for her Alzheimer’s-stricken father, has now written a book about her experiences titled “Measure of the Heart: A Father’s Alzheimer’s, A Daughter’s Return.” She was interviewed Sunday on KCBS’s “In Depth” program (here’s a link to the 30-minute program).

Geist left her spot as co-anchor of KGO-AM’s morning news in 2004 for CBS Radio in New York. A year later, she asked CBS to be let out of her contract so she could return home to Michigan when her father’s Alzheimer’s got to be too much for her mother to shoulder alone.
