Nice to meet you! I’m Kate, a 37 year old career nanny who moved from Chicago to LA in 2021 for a jet-setting/bi-coastal, travel heavy nanny position, and once the position ended, I decided to stay out here permanently. I live in Orange County with my girlfriend, and work M-Th, 7a-7p, in Studio City. My previous position was Jan ‘23- Nov ‘24. My background has always been in early childhood, and majored in early childhood education in college. I have years of experience with all age ranges and backgrounds: from kids who thrive in group settings to kids that do best with individualized, 1:1 care to kids who are neurodivergent. My first and top priority is the safety and wellbeing. Second is play, exploration, imagination, creativity, and seeing kids explore based on what they are into and things they find interesting. Third is, in my day-to-day, I take a child-centered approach. Including, but not limited to: time outside, walks, going to playgrounds, and finding activities within the home that the kids enjoy. My experience includes: working as a in-home support worker with neurodivergent kids, have worked at 3 early childhood centers (both as an assistant teacher and lead teacher); and all my experience has been from newborn to school age. In my free time: I love checking out new restaurants, adventuring the outdoors with my girlfriend, finding new trails to hike on AllTrails, the beach, and weekend trips

“Kate was amazing with our 2months old daughter. Definitely recommend and will for sure have her helping us again. ❤️🫶🏼 ”

Hey there, my name is Jenny. Nice to meet you! I have been working with Urbansitter since 2013, and I have made meaningful connections with families over the years. Though I’m currently pursuing a doctorate in Acupuncture and Chinese Medicine, I still find joy in babysitting when my schedule allows. I’m known for being patient, goofy, and communicative. My professional background is rooted in hospitality and technology, but I’ve always had a passion for working with kids in diverse settings. I coach volleyball and volunteer as a camp counselor at The Painted Turtle Camp. I’ve also had the privilege of tutoring elementary school kids via Reading Partners and mentoring with Access Youth Academy. Each of these experiences has enriched my ability to connect with kids and support their growth in fun and creative ways.

“Jennifer was very nice and our 3 boys really liked spending the evening with her! She was professional and timely and even honored our request to speak Spanish with our children while she was babysitting them. Would definitely use again as a babysitter.”

Hello, my name is Allyssa, and I am a current grad student at San Jose State University pursuing my dream of becoming a Speech Language Pathologist. I pride myself on being responsible, reliable, and full of energy, especially when it comes to working with children. Being the oldest of four, I have gained extensive experience caring for children of all ages. Back home in Orange County, I had the opportunity to work with up to four different families, ranging from ages 1-15 years old. Now, I am actively seeking part-time and one-time job opportunities that align well with my academic commitments. In addition to creating a joyful and engaging environment for kids, I can also handle meal preparation and provide homework assistance. On a personal note, I had the privilege of playing collegiate soccer, highlighting my dedication and teamwork skills. I am fully vaccinated and more than happy to share excellent references upon request. Looking forward to the chance to connect soon!

“Allyssa is pure sunshine! She connected with my son immediately and they played and played for an hour and a half with a water break here and there (:”
