Tammy Gillis is a Canadian actress, director and producer. She portrays Deputy Marissa Staub in Freeform's TV series, Siren.


Tammy grew up in a rural Manitoba town. She took interest in acting at a young age. In high school, she joined an after school drama club. However, she didn't attend an acting university after graduating high school because of a lack of role model actors and her disbelief in her own ability to become an actor herself. So she took a safer route, going to college to become a lawyer, only to later transfer to business, the faculty of commerce. During which time, she was scouted to model though it wasn't an interest of hers. She then began to audition for commercial and short films. This led to a well established career in acting.
