My name is Cassia. I have a strong background in education and childcare, with experience working as a teacher in Mexico, Singapore, and the United States. I have worked with children from age 2 through middle school. I am also a mother of two, so I bring both professional and personal experience. I speak English, Spanish, and Portuguese. I am responsible, patient, warm, organized, and caring, and I enjoy creating a safe, positive environment where children feel supported. I can also help with pets and provide loving, reliable care for them. I am comfortable supporting elderly adults with kindness, patience, companionship, and respect, always making sure they feel valued and cared for.
I have a strong background in caregiving that began in my high school years, where I regularly babysat for families in my community. As the second oldest of six girls, I grew up helping care for my five younger sisters, so nurturing, guiding, and supporting children has always been a natural part of my life. I’m comfortable with kids of all ages and understand how to keep them engaged, safe, and cared for. I also have plenty of experience with pets. I grew up with two dogs at my mom’s house and now have one of my own, so I’m very familiar with feeding, walking, and giving animals the attention they need. In addition to childcare and pet care, I’m highly organized and maintain a clean, tidy space. I’m able to help with light housekeeping, daily routines, and anything that keeps a home running smoothly. Overall, I’m patient, responsible, and genuinely enjoy supporting families. My mix of experience, personality, and hands-on caregiving makes me a reliable and trustworthy helper.
Hi! I'm Faatimah - former teacher/babysitter, current small business owner. I have worked with children for over a decade, and spent the last few years working primarily with one family (two kids, one of whom I helped raise from infancy). I am very comfortable with infants, and spent the last few months doing night nanny duties for a NICU premie after he came home from the hospital. I am very comfortable handling multiple children at once. Open to part-time mornings/ occasional sittings only.
I truly enjoy connecting with families and caring for their children. I find it so rewarding to support them as they grow into their little personalities. I have hands on experience working in a pediatricians office as well as on a Mother baby unit at Overlook Hospital where I support moms with their newborns during their postpartum stay. I am BLS certified and can bring a calm, attentive, safety-focused approach to childcare.
Hi, My name is Lesley, and I'm currently work in the public school system. I am offering my child care services. With over 8 year working with children in schools and 17 years of hands-on parenting, I bring patience, responsibility and a supportive approach to childcare. As a parent , I understand the importance of creating a safe, fun and engaging environment. My experience includes assisting with homework, organizing activities and ensuring your child’s well-being. I am responsible, patient and reliable. Whether it’s school task, meals, or playtime, I make sure children feel safe an happy. Your child’s care is my priority.
