Staci Keenan the actress from, 'My Two Dads 'is still alive. Currently, she is 37 years of age as she was born on June 6, 1975. She is also married to Guy Birtwhistle and her career has boomed ever since young age.
As far as I can tell she is still alive. There is one blog reporting that she died sometime last year but I can't find anything that backs that up. Both IMDB and Wiki still list her as being alive as well.
