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 Yulianna and I'm currently a junior at SJSU. I am offering child care, senior care, and household services. I love being a babysitter and have been watching, infants, toddlers, and kids. I have a strong background in working with children, working as a teacher aide and teacher for schools throughout the Bay Area. I am a registered behavioral technician and am CPR/BLS certified. My responsibilities have included driving to/from school, crafts, tutoring, and even dance lessons. I also work as a household assistant and can cook, clean, and run errands. I have been a caretaker for my own grandparent and am comfortable with senior care. I can cook, drive to appointments, or do other tasks. I am allergic to cats but happy to work with families with dogs.
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.
⸻ Since 2007, I have dedicated my professional life to working with children and supporting their growth, development, and success. My background as a special education teacher has given me extensive experience working with children of different ages, personalities, learning styles, and abilities. Throughout my career, I have developed strong skills in patience, communication, organization, problem-solving, and emotional support, all of which I believe are essential qualities for an excellent caregiver and nanny. Working with children is more than just a job for me—it is something I genuinely enjoy and feel passionate about. I take pride in helping children build confidence, achieve goals, and feel safe, supported, and encouraged in their daily lives. As a special education teacher, I work closely with children who have unique learning and developmental needs. This experience has taught me how to be adaptable, compassionate, and attentive to each child’s individual personality and needs. I understand that every child learns differently and responds differently to situations, routines, and communication styles. Because of this, I always approach caregiving with patience, understanding, and flexibility. I believe children thrive best when they feel heard, respected, and cared for in a positive environment. Over the years, I have worked with students on academic goals, social skills, behavioral development, emotional regulation, and daily life skills. My work requires consistency, creativity, and the ability to remain calm under pressure. I have learned how to encourage children in a supportive way while also maintaining structure and routines that help them feel secure and confident. These same skills translate naturally into being a nanny and caregiver. I understand the importance of creating a stable, nurturing, and positive atmosphere where children can grow emotionally, socially, and academically. One of the things I enjoy most about working with children is helping them recognize their strengths and abilities. I believe every child has potential, and I enjoy finding ways to motivate and encourage them to succeed. Whether I am helping with homework, guiding a child through challenges, organizing activities, or simply spending quality time together, I strive to create meaningful interactions that support their development and happiness. I truly enjoy seeing children gain confidence, learn new skills, and accomplish goals.
