Rosenthal was born in Massachusetts and graduated from Mount Holyoke College in 1979. She settled in New Orleans, Louisiana where she continued working as an active volunteer for her alma mater. In 2005, flooding associated with Hurricane Katrina forced Rosenthal to abandon her home and she began to offer assistance to similarly displaced fellow alumnae.
Levees.Org
Rosenthal began organizing in response to the official narrative and response to the flooding and evacuation of New Orleans.

Rosenthal recruited actors Harry Shearer and John Goodman, to assist with outreach for the group's message. Using video, social media, letter-writing teams and numerous other means, Levees.Org has educated people worldwide on the facts surrounding the 2005 flooding. Rosenthal has been a blogger with the Huffington Post since 2009 and with the New Orleans Times-Picayune since 2007.

''Words Whispered in Water''
In Words Whispered in Water: Why the Levees Broke in Hurricane Katrina, Rosenthal gives a first-person narrative of the 2005 flooding and its aftermath that thrust her into her role as a leading voice for fact-based responses to flood threats. She describes her transformation into an advocate for education on the history of flood control failures after Hurricane Katrina had moved inland, and her subsequent work as a watchdog tracking the responses of government and media in the hours, weeks, and years after the floodwalls first gave way.
