Lisa Donahue's early life and career began with her participation in the reality television show Big Brother 3, where she was one of 12 contestants vying for the coveted title.
Following her appearance on the show, Donahue decided to pursue a career in acting, marking a significant departure from her earlier endeavors.
In the year 2004, Donahue made her debut in the film industry with a small yet notable role as Lauren in the movie Jekyll.
In addition to her film work, Donahue also appeared in a repeat guest role on the popular television series Entourage, further solidifying her presence in the entertainment industry.
Donahue's acting career continued to flourish in 2004, as she also landed a guest role in the television series Dr. Vegas.
Four years later, in 2006, Donahue was one of 20 finalists vying for a spot on the reality television show Big Brother: All-Stars, although she was ultimately not invited back into the house.
During her time on Big Brother 3, Donahue had posed for Ramp magazine, a fact that was later discussed during the "where are they now?" segment on Big Brother 4.
Presently, Lisa Donahue is employed as a waitress at The Huntley in Santa Monica, California, a far cry from her earlier days as a reality television contestant.
