*at this time I am not accepting new families but will update if that changes!* Hi there, my name is Eva and I am 27 years old. I first graduated from college in 2021, where I obtained my degree in political science, and have completed my second degree in psychology. I have always enjoyed and excelled at working with children. For two years, I have worked with children aged infant to Kindergarten in a daycare setting and am a fully qualified childcare teacher in the state of California. Most of my time is spent with the toddler (12 to 23 months) age group, but I have experience in classrooms with children up to age 6. Additionally, I have about 4 years of volunteer experience with preschool and lower elementary aged children in both a formal and summer camp setting. I have worked with families both on and off Urban Sitter for 3 years, with children ranging in age from 1 to 10 years old. The opportunity to impart knowledge and bring joy to children, or even be a playmate, is a rewarding experience - I believe children can be our teachers too. I understand how crucial it is that you feel comfortable with the person taking care of your children - and I would be happy to speak further, answer any questions, or tell you more about myself.
“I can’t say enough good things about Eva. She’s been my two-year-old’s teacher since he was just one, so we’ve known her for about 18 months now. Over that time, she’s been super reliable, caring, and just really great with kids. She has also baby sat my son individually at our house, and helped with his laundry, dishes and food. He loves his one on one time with her. She has an awesome way of connecting with little ones by talking to them at their level and really getting where they’re at. She also brings in fun, helpful developmental activities that have been great for our child’s growth. Eva has truly become part of our support network. We trust her with our eyes closed and always feel completely comfortable leaving our child in her care. Any family would be so lucky to have her.”
My name is Rocio. I am bilingual in English and Spanish and have over 15 years of experience working with children of all ages. I am CPR, First Aid, and AED certified and can provide excellent references upon request. Caring for children has always been my passion. Throughout my career, I have worked in both professional educational settings and as a nanny, helping children grow, learn, and feel safe and supported. I pride myself on building strong, trusting relationships with children and their families. Many of the children I have cared for have remained an important part of my life, and I am honored by the bonds we have created over the years. Families describe me as nurturing, reliable, patient, energetic, and highly engaging. I love creating fun, meaningful experiences for children while also providing structure, consistency, and encouragement. Whether it’s helping with homework, planning activities, exploring outdoors, or simply being a trusted adult in a child’s life, I genuinely love what I do. In my free time, I enjoy hiking with my dog, spending time with family, and being outdoors. I am outgoing, cheerful, and bring positive energy wherever I go.
“Our kids ask Rocio to come back every day. That tells one a lot - kids are picky (at least mine 3&5 year old)”
Hi! My name is Rebecca, I am 24 years old, and a recent graduate from UC Berkeley. I currently work part time as a Partnership Coordinator for the childcare non-profit Nurture, and as a behavioral class aide to autistic elementary students. I am Adult and Pediatric First Aid/CPR/AED certified. I offer child care, senior care, and household services. I believe that play-based learning in a structured and nurturing environment is the key to healthy childhood development. 🌱 I love arts and crafts, can help with homework, and can drive to/from school. I love cooking and am happy to work with animals as well! 🐾 I have extensive experience in child care as I have been a family babysitter since I was 15 years old. I have also worked through IHSS as a caregiver for a high support needs autistic woman with an intellectual disability. These experiences have taught me patience, compassion, and the importance of accommodating different learning styles. Additionally, I have experience caring for an elderly family member with dementia, which then transitioned into end-of-life care. As an undergrad, I was a dedicated member of the Sage Mentorship Project. I served as a mentor and Program Director for students at Sylvia Mendez Elementary and Fairmont Elementary. I’m excited to meet you and your family! ☺️
I am a full time employee as a diesel mechanic at a local tractor shop and a part time student. I also am in the middle of trying to get my own small business up and running. When I am not at school I am hanging out with my family, cooking family dinners or cleaning or maybe even studying for my classes! I have taken three years of American Sign Language in High School. I am not fluent but will be more than happy to try my best if it will come in handy! (Please be understanding I am rusty since I don’t use it much) If you have any questions at all please feel free to message me!
“Ashley was great. Showed up on time and had an easy-going engagement with my son. She fed him and put him to bed, and Nik had a great time.”
