About Sienna
Hi! My name is Sienna. I started performing when I was 2 years old in Southern California and have continued my passions since moving to the Dallas area with my family. I love being in front of a camera or a live audience. I am spirited and confident and I like trying new things.
My talents span across acting, modeling, singing, songwriting, hosting, producing, and dance — including Ballet Folklorico. I'm SAG-E with credits on Nickelodeon, ABC, FOX, NBC, and in multiple films and music videos.
I'm the creator of KISSbySienna, a show dedicated to my love of KISS. I also served as Executive Producer on Gene Simmons' legendary box set, The Vault, when I was just 11 years old.
Beyond performing, I enjoy travel, camping, fishing, baking, and theme parks!

The Story
At age 9, on a KISS Kruise, Sienna's parents bought her a Gene Simmons bass guitar. When she met Gene to get it signed, something magical happened — they wrote a song together called "I Hate Multiplication."
That chance meeting sparked a lasting friendship. Gene invited Sienna to serve as Executive Producer on his legendary box set, The Vault — making her one of the youngest executive producers in music history at just 11 years old.
KISSbySienna was born from her passion to share KISS with a new generation. The show features her massive KISS kollection, concert experiences, and behind-the-scenes moments — proving that rock 'n' roll has no age limit. Her first KISS concert was at age 3, and her last was the legendary End of the Road tour in December 2023.
