Hello! My name is Juliana, and I am 18 years old. I was born and raised in Oakland, California, and I am currently pursuing a degree in Education with a minor in Child Development. Working with children is something I am truly passionate about, and I have over four years of experience caring for and mentoring kids of different ages. I am energetic, responsible, and dependable, with a fun and goofy personality that helps me build positive connections with children. I enjoy creating engaging activities, supporting learning and development, and making sure children feel safe, happy, and cared for. I also have quick reflexes and stay attentive at all times, allowing me to respond quickly in any situation. My goal is to provide a nurturing, supportive, and enjoyable environment where children can learn, grow, and have fun. I look forward to bringing my experience, enthusiasm, and dedication to your family.
Hi! I’m a caring, patient, and energetic caregiver who genuinely loves working with kids. I have experience with children of all ages and personalities, and I always aim to create a safe, fun, and supportive environment where kids feel comfortable and included. I currently work at an after-school program, which has helped me build strong skills in staying organized, keeping kids engaged, and handling different situations calmly. I also volunteer on some Sundays at a children’s ministry at church, where I usually work with toddlers—so I’m very comfortable with younger kids as well! In my free time, I enjoy staying active and being outdoors, and I like bringing that same fun, positive energy when I’m with kids—whether that’s playing games, helping with homework, or just keeping them entertained and happy. I’m reliable, easygoing, and someone parents can trust to take great care of their kids while making sure they have a good time too!
“Very professional and great w small children”
I am a 2nd grade teacher with an Early Childhood Education background. I have been teaching for 6 years. Prior to this I was a full time nanny or live in nanny from 19-26. I have cared for a variety of children from infants to teenagers. My primary care has been infants through age 8. I have cared for high special needs kids as well such as Down syndrome, autism, and childhood cancer. I also am a mom to a level 1 autistic child who’s 7. I am seeking part time work and would not be bringing my own child. I work full time as a teacher during the school year and will be off all summer seeking occasional babysitting or tutoring if interested.
Hi, my name is Caroline! I live in Oakland and am a Saint Mary’s College of CA alum for both my undergrad and masters degrees. I currently work with children and families in early intervention mental health as a therapist and have had a variety of roles within the child development field for the last 10+ years. I have also babysat all different age groups since I was a young teen and am looking forward to continuing! My responsibilities have included driving to/from activities, nap and bedtime, meals, light household responsibilities, arts and crafts, outdoor play, etc. I’m a very patient, flexible, and fun loving person. In my free time, I love exploring the bay, trying new restaurants with friends, and traveling. Looking forward to connecting and working together!!
I have a Bachelor's degree in Kinesiology with a concentration in exercise and movement science and I have about 11 years of recruiting experience in biotech. I recently got laid off from work and I am looking to do something meaningful in the meantime as I transition to my next role. I enjoy working with children- I have previously coached kids on various sports and did a summer camp at SFSU.

"Caitlin was awesome and jumped right in to chaperone four girls (10, 9, 8 and 6) at a family wedding (they were bridesmaids) and she was very helpful with the event as well as taking them home and putting them to bed."
Lila P., parent

"McKenna was great with our 3 year old son! She came prepared with a box of fun activities and handled playing, dinner, and bedtime seamlessly... and it was all at our hotel while we were in town for a wedding. Thank you McKenna!"
