Trish Rainone began her artistic journey as a competitive dancer. In her 20s she ventured into film with a small appearance as a Sunshine Girl in the Trailer Park Boys movie, Swearnet. She later secured a principal role in a horror film, prompting her move to Toronto for a career in film, theatre, and television.

Trish had a brief experience on set as a child on YTV's crafting series, Hands Up! Hands On! It was actually a run in at The Excalibur in Vegas with Chevy Chase & the crew of Vegas Vacation while there for a dance competition that peaked her interest in film. She didn't end up pursuing it until many years later, as filming in Sault Ste. Marie was unheard of at the time. Trish attended Film Studies at Carlton University after high school and then transferred Universities, gained a Degree in Psychology and a Diploma in the Behavioural Sciences. Following Swearnet & the horror film role, she decided to pursue acting and film/tv full-time in Toronto.

Trish's breakthrough came with a union speaking role in the cult hit, The Void, leading to her membership in the Canadian actor's union, ACTRA. Co-creating and co-writing My Roommate's an Escort, she showcased her comedic talent for two seasons, and was nominated for Best Actress at TO Web Fest in 2017 in Toronto. The series gained awards at festivals world-wide. She currently portrays tough girl, Top Dog, in all episodes of the prison comedy, Pink Is In. The Hamilton, Ontario based series has earned ACTRA Award nominations for Series Ensemble for three consecutive years and can be streamed in multiple countries.

In 2023, she played Tina in the interactive live wedding show, Tony n Tina's Wedding, with the Algoma Repertory Theatre in Sault Ste. Marie. "Rainone's Tina is a spitfire in white lace and it's hard to take your eyes off her." - Robin Waples, The Sault Star, Mar 28, 2023. Additionally, in early 2024, she portrayed Shelby in Algoma Repertory Theatre's production of Steel Magnolias, performing to sold-out crowds.

Actively contributing to her community, Trish co-founded the Sault Film Festival in 2020. She served as a producer for the Musical Comedy Guild of Sault Ste. Marie's Fiddler on the Roof in 2023.

Trish has also produced a series of films and short-form content, including the feature film, A Christmas Letter, on CBC & UPtv. She makes a cameo, which John Doyle reviewed in The Globe and Mail. "Rainone also does a great turn as a snarling, tough waitress." - John Doyle, The Globe and Mail, Nov 30, 2021.
