A product of the Celtic academy, Sienna continued to impress through the Hoops ranks, the 23/24 campaign seeing her named as the Under 18 academy player of the year.
Having her ability boosted with game time experience, she saw a successful season long loan spell with Motherwell that saw goals in both the cup and in the league, ultimately aiding in the North Lanarkshire sides top six finish.
The versatile midfielder is also a prominent name on the international stage with frequent appearances for Scotland at youth level.
She started her loan spell at thistle in quite possibly the best fashion that could be asked for as she debuted from the bench just hours after signing, winning possession before turning in the box to drill the low finish into the bottom corner in the fourth minute of injury time to secure Thistle another top 6 finish.
