Following in her older sister's footsteps, Mackenzie has been dancing since the age of two. In 2011, Mackenzie, her sister Maddie, and their mother Melissa Gisoni were cast on Lifetime's hit reality TV series "Dance Moms", which allowed Mackenzie to grow as an artist and pursue other passions such as acting and singing. On the music front, Mackenzie released her debut album in 2014 which soared to #1 on the iTunes pop chart list, #7 on the overall album charts, and her music video for the song "It's A Girl Party" reached #1 in the US, UK and Australia. Mackenzie went on to record and star in "Freaks Like Me" by Todrick Hall and later recorded "Day & Night" with Johnny Orlando.

In 2017, Mackenzie released the single "Monsters (aka Haters)". The song was a trending track on YouTube's top 15 and was featured on Sirius XM1 Hits. She followed this up with "Teamwork". The song is part of a collaboration with Justice stores to unveil her activewear collection with the brand. "Breathe" is her most recent release and the song that Mackenzie calls her favorite. Her music videos have received collectively over 150 million views to date. 2017 also marked the start of live touring for Mackenzie as she embarked on the "Day & Night" tour with Johnny Orlando.

Mackenzie has twice guest starred on Nickelodeon's Nicky, Ricky, Dicky & Dawn, was nominated for a Teen Choice Award for her social media as Choice Muser, was the face of Clean & Clear's Fall back-to-school campaign, starred in Ralph Lauren's Kids Spring and Fall/Winter campaigns, and on top of all of this, she has announced a 2018 book!
