In a surprising revelation that speaks to her supportive nature, Tarek once shared that he had hit a low point in his real estate career and lived in his mother's garage.

European Roots, Privacy, and Why She Avoids the Spotlight

One of the most defining characteristics of Dominique El Moussa-Arnould is her preference for privacy, a stark contrast to her son’s career on reality television. This desire to remain out of the public eye is deeply rooted in her background and personality.

Dominique is of European descent, with reports citing her heritage as Dutch and/or Belgian. Tarek’s father, on the other hand, is Lebanese Catholic. This diverse cultural background has undoubtedly shaped the family's values, perhaps contributing to a more reserved and traditional approach to public life compared to the typical Southern California reality TV sphere.

Her decision to maintain a low profile is a deliberate choice. While Tarek and Heather share virtually every aspect of their lives on social media and their HGTV show, Dominique only appears in carefully curated family photos. This allows her to support her son's successful career without sacrificing her personal peace or privacy. She is the quiet force, preferring to offer her love and support behind the scenes rather than seeking the fame that comes with the El Moussa name.

Dominique’s influence is clear in Tarek’s life. She instilled in him the resilience and work ethic that allowed him to bounce back from financial hardship—including the period where he lived in her garage—to build a real estate empire. Her life story, though largely untold in the media, is a powerful narrative of a dedicated mother and grandmother who prioritizes family bonds above all else, making her the essential, private matriarch of the El Moussa clan.
