Montreal-born Stephanie Castagnier lost her parents to AIDS when she was a teenager, which taught her how to fend for herself ever since. She worked full time while studying at McGill University, and upon graduation she worked as a commercial banker. She was later ranked among the top commercial lenders in the country for a number of years, until tragedy struck and the recession hit the financial sector. Despite her losses, she founded the non-profit organization Child Cause/Fear to Fire, which provides help to teens affected by AIDS and substance abuse. She has also written a book titled "Fear to Fire", in addition to her work as a national speaker.
In 2010, Stephanie Castagnier was chosen as a contestant in NBC's The Apprentice. She was praised for her work, but was fired in the tenth episode because of the poor results she produced in the project. After leaving the show, she strived hard and became the President and CEO of Hudson Financial Group headquartered in Chicago.
