Hi! I’m Malissa — a reliable, flexible babysitter with 10+ years of experience. I’m 32, have my own car, and work with several wonderful families on both a weekly and occasional basis. I offer date night, overnight, and travel care, as well as pet and house-sitting. I work fully remote Monday–Friday (8–5), which allows me to help with school pickups, bring kids home, and keep them safe and engaged while I finish my workday. I’m happy to work from your home with Wi-Fi and a place to sit—this setup works great for the families I currently support. I’ve cared for children ages 0–17 and can help with homework, meals, light tidying, bedtime routines, and pet care—while making sure your kids are safe, happy, and well cared for. I accept Apple Pay, Zelle, check, and cash, and ask that payment be made by the time I leave. Overnight and travel care are available with custom rates, and I request toll reimbursement when applicable. I love building long-term relationships with families and look forward to meeting you! Warmly, Malissa
Hello, I look forward to meeting your family and pets. I have experience with giving care for 1-9 year olds. I have 2 nieces ages 2 and 5 years old, so I have changed many diaper, planned outdoor activities, and made their day with less screen time. I have personal experience with raising, training, and caring for dogs. I am a masters of nursing student so my time may be limited due to school, but I would love to spend any free time I have babysitting for any family members.
“Tina helped keep an eye on our little one during a family party at the park. It was a unique situation but Tina was game for the challenge. Very communicative, sweet, and flexible!”
Hi! My name is Cassandra. I am from Vallejo, CA. I am a college graduate with a B.S. in Molecular Biology and a Minor in Chemistry from Dominican University in San Rafael, CA. I graduated in May 2018 with many honor society achievements and graduation honors. I’m also currently finishing up a B.S. in Nursing! I've had a lot of experience babysitting children of all ages from infancy to preteen and some teenage. I am certified for Basic Life Support for infant/child/adult, which includes CPR/AED. I am also an instructor for both! A little more about me... Currently, I am a high school science teacher (Chemistry, Biomedical Innovations and Medical Interventions). I've played competitive basketball and volleyball as well as the piano all my life. Additionally, to continue my love and passion for sports, I volunteer my time to coaching girls basketball and volleyball. I am the head coach for the JV team and an assistant coach for the Varsity team at a the private high school I teach at. I am also the JV head coach for the volleyball team! I speak a little Italian and I can fully understand Tagalog. I’m hoping to take classes soon to be fluent in Italian again! I look forward to meeting and helping your family!
Hi! I’m Julia, a professional nanny with over 10 years of experience supporting families and caring for children of all ages, from newborns to school-aged kids. I have a Bachelor of Arts in English from the University of São Paulo and over 12 Early Childhood Education credits, which have helped me develop a strong foundation in child development, communication, and creative learning. I’ve worked with a wide range of families, including those with infants (starting as early as 4 months), premature twins, toddlers, and multiple siblings. My experience includes everything from bottle feeding, sleep training, and potty learning to creating educational play activities, supporting developmental milestones and organizing enriching outings. I’ve also navigated food allergies, maintained structured routines and provided overnight care when needed. I believe in a gentle, respectful approach while holding firm and loving boundaries and I love fostering independence, curiosity, and confidence in every child I care for. What I love most about nannying is forming deep, trusting relationships with the children and families I work with. It’s incredibly rewarding to watch little ones grow and thrive in a safe, nurturing environment where they feel seen, supported, and celebrated. I aim to be a calm, steady presence in a family’s life. Someone who brings joy, structure and a helping hand whenever it's needed. A little about me: I live in Walnut Creek with my wife and two dogs. I’m fluent in both English and Portuguese, have a clean driving record and am certified in First Aid and CPR. Outside of work, I enjoy photography, cooking, hiking, and hosting friends for game nights or home-cooked meals. I’d love to learn more about your family and how I can support your child’s growth, happiness, and daily routine. Looking forward to connecting!
“Thanks so much, Julia! Can't wait to have you back!”
Hello! I am a proactive, responsible and dedicated nanny, family assistant and household manager. I have 10 plus years of recent professional experience, excellent references, letters of recommendation, and I am currently looking for evening jobs! I love adventuring with kids or interactive playtime at home. I enjoy going for hikes in nature, walks to the park, library or museums, spotting airplanes, wildlife, flowers, great books and art. I also like playing games and doing arts and crafts, building lego creations & forts, playing with dolls and animals, or reading books with hot cocoa on a rainy day. A simple peek-a-boo session, singing ABC’s, practicing counting or tummy time for the little ones:) I have experience providing support with school drop off/pick up, driving children to and from after school activities, homework assistance, as well as household chores, preparing snacks & meals, doing laundry, running errands, dog walking, traveling with the family and overnight care. In addition, I have experience managing and assisting with household inventory, scheduling appointments and communicating with contractors, housekeepers or caterers, organizing closets and calendars, and managing packing lists and travel preparations. I am discreet and respectful of a family’s privacy when needed and yet I welcome sharing a meal with them when invited. I am flexible enough to calmly transition from meal prep to children to dishes and back to children again:) I am very healthy and live an active lifestyle outside of work. I am close to completing an associate in arts degree for transfer. Please feel free to reach out to me with any questions. I look forward to connecting with you soon!
