Hillier then left SUA TV to pursue studies in New York City, focusing on Broadcast Journalism at the New York Film Academy. During this period, she also studied Acting for camera, films, commercials, and teleprompter usage. While in school, she interned with Veja TV, another Brazilian television network, where she had the opportunity to interview many more major celebrities. She then began working with the Brazilian TV show "Primeira Classe," where she explored New York City's hottest spots and major events, such as New York Fashion Weeks, numerous gala parties, and prestigious award events like the Emmy Awards and AMFAR charity galas. Covering these fashion events sparked Hillier's interest in personal styling and image consulting, leading her to start a fashion, beauty, and lifestyle blog, www.sharistylenyc.com. The blog, directed towards the modern woman, promotes the belief that all women can feel self-confident in all areas of life by being well put together.

Hillier started a new chapter in her career and focused on empowering women through a beautiful concept at Nuovo Artistic Photography, where she discovered the power of helping women find self-love and self-confidence. This inspired her to share stories of successful women who had overcome various struggles, aiming to inspire and encourage other women to believe in themselves and the power of self-love through her podcast. Early in her career, Hillier arrived in the U.S. from Brazil in 1999 after studying Science of Nutrition at PUC University in Brazil. Her journey began in Boston, MA, where she attended ESL classes at Harvard University and held several jobs to support her education. During this time, she also took various acting courses and workshops. As her career progressed, she moved to New York City in 2008 to continue her studies and further her career.
