In addition to musicals, Mackenzie loves “being in the booth” and lending her voice to voice-over work.

Mackenzie has also performed voice-over work for BabyFirst TV and Mike & Mia.
Mackenzie has appeared in web series and commercials, including a fun web series baking show, Kids Chef Bakes, where she was the Kid Chef Host alongside Celebrity Chef, Rocco Dispirito.
Mackenzie has performed in cabarets at the Green Room in NYC (Young Broadway Series & A Time to Shine), Don’t Tell Mama (Safe & Sound Musical Cabaret), The Triad, The West End (All Star Cabaret), as well as virtually on Social Media for A Time to Shine, Rising Talent Magazine, AI Coffee House Live and more. She has also sung the national anthem at events, including singing at Yankee Stadium for an NYCFC soccer game.
Mackenzie has been singing since she could babble, performing her favorite movie, Broadway, and pop songs for her family from the age of two. Singing is her passion – she sings all day long, loves discovering new artists on social media, and has even written her own single, “I Try,” which is available on all streaming platforms. In her free time, Mackenzie also loves to draw, bake, crochet, play ukulele and piano, and hang out with friends.
