AnnMaria De Mars (née Waddell; born August 15, 1958) is an American technology executive, author and judoka.

[1] De Mars is the chief executive officer of 7 Generation Games and The Julia Group, as well as a statistical consultant and activist, having authored grants for various Native American programs.

She missed the first women's world championships while in grad school, but in 1981 won bronze in the British Open and Tournoi d'Orleans.

De Mars pursued further study, including an MA and PhD in Educational Psychology from the University of California, Riverside;[8] which came in handy while teaching her daughter Ronda the proper mindset to take before fights.

In 1995, De Mars' then-husband Ronald Rousey suffered a sledding accident which resulted in a broken back and chronic pain.

[10][11] Following this, De Mars moved her family back to Southern California and settled in Santa Monica, where she homeschooled her children.

While there, De Mars performed evaluations for talent search, vocational rehabilitation, Health Careers Opportunity Program (HCOP), Even Start Family Literacy and SAMHSA Grants.

In the founding of 7 Generation Games, De Mars' focus comes from The belief that children fall behind in school early in mathematics and it hurts their opportunities their whole lives.

My idea for a math game came following meeting my partner (Dr. Erich Longie) and I attended in Washington, D.C. to analyze the National Indian Education Study.

Erich was president of the school board on his reservation at the time and he told me, "We need to come up with a way to incorporate math and culture because I'm not willing to give up either one in my grandkids' education."

Our team designed and developed a game that is a 3-D virtual world where kids are attacked by wolves, hunt buffalo, escape from enemies and have to use math at every turn.

[19] De Mars is the mother of Ronda Rousey, an Olympic bronze medalist judoka and former UFC Bantamweight world champion.

She is also the mother of María Burns Ortiz, a sports journalist who serves as the social media columnist for ESPN.com and as a contributor to Fox News Latino.
