Laguens grew up in a middle-class family in Louisiana. Lyndon B. Johnson happened to be at her baptism and held her briefly, a fact to which her family later jokingly attributed her Democratic affiliation. She has stated that she was "always pretty political" and "way more liberal than probably my whole family." Her early activism dates to when she was in third grade; she started a student council due to unfair playground rules that discriminated against the female pupils.[citation needed]
Through late 2010, Laguens ran a Democratic political consulting firm. She also served Planned Parenthood as a brand consultant for ten years before being recruited to serve full-time as executive vice president and chief brand officer,[24] a post she took in January 2011. She remained with the organization through 2018. During her tenure, she led the organization through numerous programs and initiatives, such as resisting 21 Trump-Pence congressional attacks to defund Planned Parenthood; growing the organization from 2 million to 12 million members; helping develop a period tracker app for the organization; promoting and expanding access to birth control across 50 states; developing the Planned Parenthood Action Fund, the organization's political advocacy branch, and more.[25]
After her departure from Planned Parenthood, Laguens became strategic advisor at Redshift Leadership and the Vaid Group and the expert-in-residence at IDEO.
Laguens is married to Jennifer Treat. The couple has triplet daughters, Katherine "Kate", Hallett, and Sydney Treat, who were born in 1998.[28][29][30]
