Hello! My name is Ella and I am a recent college graduate interested in working with kids! I love babysitting toddlers and kids -- I have previously wrangled little ones moving through summer theatre and dance camps, and I have special skills in working with easily distracted kids and getting them back on track :) I am also available to catsit, dogsit, and housesit upon request!
Hello! My name is Katie. I have been working as a full time nanny for the last 6 years, and babysat for several years prior as well. I have cared for kids aged 4 months to 10 years, and also helped as a household manager- scheduling appointments and running errands. Additionally, I have experience working in a Montessori school/daycare. I would love to chat more and see if I could be a good fit with your family!
Hello folks! I am Elizabeth and am so excited to meet you! I am happy to offer child care, senior care, and household services. I have a car and am available to help with driving tasks. I have over five years of experience in healthcare. As a float pool nurse, I worked in units all across the age spectrum from adolescent psychiatry to geriatric care. Therefore, I am very comfortable working with children and folks of all ages and abilities. I have my basic and advanced life support licenses and an overall focus on the well-being and joy of those I interact with. Additionally, I have a background in outdoor education. I’ve worked as camp counselor, soccer coach, and as well as a facilitator for team building workshops. I love to be outside and I love to help others explore the world around them in order to discover and grow into themselves. Happy to work with families with dogs, but I am allergic to cats. Thank you!

"We were incredibly grateful that Maya was able to help us out with a last-minute childcare emergency. She matched our 9-year-old's energy with arts & crafts, some quiet reading, and a walk around the neighborhood. We'd have Maya back in a heartbeat!"

"We used Tania for a last minute emergency. She responded very quickly. My daughter seemed to enjoy herself. My son napped most of the time. I enjoyed how she kept me updated by text."
