According to her IMDB page, she has quite an impressive resume as an actress, although I personally will always know her as Deanna Troi, because I grew up on Star Trek. Well, I also remember her as Demona in Gargoyles, which was weirdly like Star Trek in an alternate universe, with the mix of voice talent. And, that appears to have been a deliberate thing*. Anyway, back to Sirtis; 2016 looks like another good year for her, as it appears that she’s got several projects in the works. Apparently, she caught the acting bug when she was quite young and is still going strong, and good on her for that!
*Scroll down to #13, if you’re interested in Gargoyles/Star Trek crossovers.
