I have 4 years of experience working in a daycare, caring for multiple children from 18 months to 5 years old. I also have experience caring for twins under 2, a 4-year-old boy, children with special needs, and infants from 4 months to 1.5 years old. I’m responsible, patient, and caring, and I really enjoy working with children and helping them learn and grow. I’m CPR and First Aid certified, a confident swimmer, and a safe driver. I’m comfortable with daily routines, playtime, meals, bath time, and keeping children safe and engaged.
Hi there! My name is Tara. I have my Bachelors in Business Administration and work in the tech field. Since childhood I’ve been passionate about helping children learn and grow. I’ve been a nanny since I was a child myself, starting with a baby-sitters club I made with my best friend in 6th grade. I have extensive experience working with infants to grade school aged children and also focused my early career working at Challenger School and nannying for various families. I enjoy spending my spare time singing, reading, gardening, creating art, baking, traveling to new places, skiing, spending time outdoors, and being around family.
Hi, my name is Elysia, and I am currently a senior at UCLA. I have a passion for working with children and serving our youth in any way I can. Kids truly bring so much joy to life, and I love connecting with them while supporting their growth, confidence, and creativity. I hope to not only be a caregiver, but also a positive mentor and role model for the children I work with. I have hands on experience working at the Boys & Girls Club, where I formulated weekly lesson plans that encouraged student participation through interactive activities and creative projects. I focused fun and engaging learning experiences while fostering an environment where children felt safe to express themselves and develop critical thinking skills. Creating a supportive and welcoming space was always my top priority. Through this role, I demonstrated strong leadership and mentorship by guiding students in personal growth, helping them set attainable goals, and motivating them through positive reinforcement and recognition of their accomplishments. This approach helped increase their self confidence and enthusiasm toward both academics and daily life. I also implemented structured daily routines to provide consistency, while maintaining a warm, caring, and positive attitude when working with both individuals and groups of children. Overall, I strive to ensure a safe, nurturing, and encouraging environment where children feel comfortable, supported, and inspired to be their best selves. I truly love working with kids and feel grateful for the opportunity to make a positive impact in their lives.
Hi! My name is Madison, and I’m a 22-year-old college student based in Union City. I have experience caring for children of different ages and enjoy creating a safe, fun, and supportive environment where kids can learn, play, and feel comfortable. I am CPR and First Aid certified and understand the importance of patience, responsibility, and communication when caring for children. Whether it’s helping with meals, playtime, bedtime routines, or homework, I strive to provide dependable care that parents can trust. I am reliable, attentive, and passionate about helping families while giving children a positive and engaging experience.
