Shark Tank star Mark Cuban's family life

Cuban's wife: Tiffany Stewart

Mark Cuban and Tiffany Stewart met in 1997 in Dallas, beginning a relationship despite their different career paths. They married in a private ceremony in 2002 in Barbados, where close family and friends attended. Stewart, who previously worked in advertising, has supported Cuban's ventures, including his purchase of the Dallas Mavericks and his role on Shark Tank.

The couple prefers a private lifestyle, occasionally appearing together at events but generally keeping their family life away from the public eye. Stewart has maintained a low-profile life, focusing on charitable work with organizations like Hoops ‘n Hopes and the Mays Foundation, aligning with her interests in youth education and community welfare.

This complements Cuban’s public-facing career, as Stewart balances family and philanthropy while Cuban remains active in business and media. Together, they prioritize privacy and simplicity in their personal lives despite Cuba's high-profile status.

Cuban and Stewart have three children: Alexis, Alyssa, and Jake. Cuban has shared his parenting approach, which includes setting boundaries on material possessions to instill values of effort and self-discipline in his children. He intends to teach them the importance of personal growth over material wealth.
