Hi, I’m Summer! I’m currently a part time nanny for twin 5 year olds and looking to pick up extra hours while I’m on break from school. I study Speech Pathology online and got certified this year to teach kids yoga which I’ve been loving and teach on occasion. I also have experience teaching swim lessons and have several years of childcare experience with kids of all ages, including multiple sets of twins. I’m CPR and First Aid certified and enjoy keeping kids engaged with fun activities that help them learn and grow.
“Summer was fantastic! She was professional, warm and engaging and my 10 year old daughter loved her from the second she walked through the door. Will definitely hire Summer again!”

I have worked with several families over the years, one of which I was with for 5 years back in Oregon. I have babysat a wide range of ages, from infants to middle schoolers. Additionally, I have experience tutoring elementary students, pet/house sitting, and 5 years of experience working in the classroom. I absolutely love working with kids and animals.

Please contact me with any questions. I would love to hear from you!
“Ellie is such a genuinely caring and compassionate person. My little one had so much fun with Ellie from the very first moment of meeting her. She had great communication both while preparing for her visit and while she was with our little one. I would highly recommend her!”
