María Múgica

About María

María Múgica had always been passionate about women's health, and becoming a mother at the end of 2024 made it personal. What surprised her most wasn't the sleepless nights, but how little support there was for her own wellbeing.

During pregnancy, information was scattered, outdated, and focused on the baby. After birth, support was even harder to find. Navigating recovery from a complicated pregnancy while caring for a newborn felt overwhelming, and advocating for herself felt like a full-time job at a time when she most needed guidance.

Everything changed when she met Sandra. Finally, María felt supported, informed, and able to focus on both her family and herself. Determined to give other women the support she wished she'd had, she now combines her background in Tech and Strategy with her own experience to make Sandra's expertise accessible to every woman, so they can also feel strong, informed, and empowered at every stage of life.
