Brielle, a native of New Jersey, embarked on a career in the entertainment industry, initially gaining experience through commercials and print work. By the tender age of five, she had already begun to secure bookings for prime-time television shows and feature films. As her career progressed, Brielle landed recurring roles on notable television series such as Royal Pains on USA and Hope & Faith on ABC. Her breakthrough came when she secured a series regular role on the USA hit series The Starter Wife, playing the daughter of Debra Messing.
Following the cancellation of The Starter Wife, Brielle and her family temporarily relocated back to their native New Jersey. However, the allure of work in Los Angeles for both Brielle and her now-established brother Thomas ultimately drew them back to the West Coast. Today, Brielle and her family maintain a dual residence, splitting their time between their permanent home in New Jersey and their Los Angeles abode.
Since relocating back to Los Angeles, Brielle has continued to appear in various commercial and print campaigns for prominent brands, including Coca-Cola, J.Crew, Mattel, Apple, and Netflix, among others. Her television credits also include appearances on Modern Family on ABC, Deadtime Stories on Nickelodeon, Trophy Wife on ABC, and Scandal on ABC.
