With the energy of a teenager, the wisdom of a sage and the memory of a super hero, Marilu Henner has deservedly earned the nickname "Perpetual Motion." A five-time Golden Globe nominee beloved for her roles on two hit classic sitcoms, "Taxi" and "Evening Shade," Henner is also a New York Times bestselling author of nine books (including "Total Health Makeover," "The 30 Day Total Health Makeover," "Healthy Life Kitchen," "Wear Your Life Well" and "Total Memory Makeover"). She has starred in over 30 films, six hit Broadway shows (including "Grease," "Chicago," "Social Security," "Over Here!" and "The Tale of the Allergist's Wife") and was a contestant on the first installment of Donald Trump's "The Celebrity Apprentice." As featured on "60 Minutes," Marilu is one of only 12 documented cases of highly superior autobiographical memory (HSAM) and wrote her ninth book, the New York Times bestselling "Total Memory Makeover" with the goal to help others tap into their memories.

Henner is representing the charity organization Alzheimer's Association®.
