🌁 Hi! I’m a native San Franciscan back after twenty years in Hawaii. I began my nannying career in Y2K, and have cared for little ones (newborns- 5 years) since then in San Francisco, Marin, and Maui. 🐣 Over the years, I’ve had the privilege of nurturing children from infancy through adolescence, including my goddaughter, who is aspirationally kind and thoughtful. 🩵 I bring an empathetic, warm, and grounded presence into the home, and always try to grow the giggles! I aim to create a safe, loving environment for children to feel confident, secure, and seen. 🎨 Trained in ballet, hula, acting, and visual arts, I love to encourage imagination and creative self-expression. 💬 With a background in public relations, I’m highly communicative, discreet, organized, and dependable. 🦺 My driver license, vaccination records (COVID x2/ MMR/ Tdap), and background checks (LiveScan, Checkr) are available upon request. ✈️ I'm able to travel with your family (USA Passport/ CLEAR/ TSA Pre-Check), and am available for overnights. 🌸 Please feel free to message me about availability, rates, or anything else; I can usually reply immediately. I look forward to connecting with your family! Aloha! **For the health and safety of all the children and families I work with, I’m unable to care for those actively sick with highly contagious illnesses such as HF&M, RSV, flu, pink eye, COVID, etc. Thank you for understanding.

Hi parents! I’ve been in United States since 2019. I came as an au pair and now I’m a college student. All this time I had the pleasure of taking care of kids from different ages: 8 months to 12 years. With the kids I like to read books, paint, play, take them to parks or different places if the parent is comfortable. I’m a person that is very patient, calm, respectful and trustworthy.
“Karen was very friendly and professional, our daughter really enjoyed her! We would definitely hire her again. ”
5 years experience as lead teacher at a Preschool in Fairfax. Associate Preschool Teacher degree with 12 ECE units. I can usually respond within one or two hours.. Patient, calm, ready to play and be of service! Originally from Toronto, I live in Fairfax and have been in the Bay Area for 16 years. My experience looking after children started in the 70’s with my own baby brother, babysitting throughout my teenage years, a young step-son and more recently my teaching work at a Preschool. I love being with all children and playing, helping with homework, reading, art, languages and piano. I look forward to hearing from you!
