Following her death, her manager Craig Dorfman remembered her as "one of the finest actresses I ever met."

He told People magazine, "I still remember seeing her onstage in 1992 in 'Mad Forest' off-Broadway. She was electric, funny, and a true individual. Everyone loved her. She will be missed."

Mara had recurring roles on "ER" (1995-1996), "Nash Bridges" (1996-1997), and "Ray Donovan" (2013).
