“Mariana has been wonderful with our family. She is reliable, communicative, and always checks in to make sure she’s aligned on what needs to be done. She helps with school pickups, homework, showers, dinner, and generally keeping the kids on track in the evenings. She’s proactive, responsible, and great with the kids! We’ve had a great experience with her!”
