As a patient, calm, and creative caregiver, I prioritize open communication with parents to ensure their peace of mind, and I follow their lead when it comes to enforcing household rules.

I have 10 years of experience working with families taking care of their kids. I’ve been working as a full time nanny and as a part time teacher. I have a BLS, CPR certification, I am fully COVID vaccinated, all the vaccines up to date such as MMR, HepB, Flu shot and more. I have my own car available to use with your kids, clean driving record, and exceptional driving skills. I enjoy being able to help in the developmental process of each child. I have been using development tools for years such as Kinedu and Baby-Led Weaning. Apps designed to support parents in nurturing their child's development through play as well providing foods that are nutritious for babies in a way that they can handle them. I’m bilingual, English-Spanish and I enjoy teaching these languages through reading, singing, play time and throughout their daily’s routine. I’m a sporting person, I like swimming, gymnastics and I workout regularly to keep myself healthy. I have experience taking the kids to swimming classes, gymnastics, and outdoors- indoors activities. I’m a Montessori fan and I’m happy to share my knowledge and experience to help your kids in a fun way to use it, love it and apply it in their lives as in their playrooms, bedrooms, pantries, meal times, hygiene routines, schooling activities and more. I’m a tidy person so I love helping out families at home. My background is in child development as well in nursing. I’m currently a CNA. I have great references from the families I’ve worked for and I’ll be happy to share them with you. Feel free to reach out to me, I’d love to get to know your family, share smiles with your little ones and be helpful in anything that you’ll need.

“Sara was super friendly with Sir Jingles! Looking forward for her to take care of him while we're gone!”
