Mireille attended elementary school in Paxton, Massachusetts, high school in San Francisco, CA, and university in Beirut, Lebanon. She majored in English Literature and later taught English for two years at Snow White Academy in Beirut until she realized this was not the path for her. Mireille quit her teaching job, flew to Paris and studied hair and make-up at the Svelte International School of Cosmetology.

She began working as a make-up artist at Nidal Bsherrawi Modeling Agency in Lebanon, a job which put her on the road to becoming a talent scout and then a Talent Manager back in the states at 3:33 Entertainment and ultimately a Talent Manager at Midwest Talent Management since 2006.
