I have 8 years of consistent childcare experience, including 3 years as a healthcare assistant at a children’s hospital and a part time nanny for a family of six kids (ages 0-16).

Booked by 2 families in Mercer Island, WA

I spent my freshmen and Sophomore year (2[removed]) at college working with preschool English language learners. From 2015 to 2018 I worked at Green Tree Early Education center in Downtown Seattle. After graduating from the University of Washington with a degree in Early Education, I went for a Masters in Computer Science from Northeastern University. During my corporate career, I worked EST which allowed me to be an afterschool nanny/manny starting during the pandemic. I have worked with 7 different families and my undergraduate education was focused on infants and toddlers. Most of my experience is in transitional care / mothers helper while the families are on a waitlist for childcare centers. However my most recent experience was as a nanny/manny for two boys with Autism Spectrum disorder. I have an outdated first aid and CPR certification but I am almost certain there has not been any significant changes since 2017. I am comfortable around pets

“My kids enjoy hanging out with Brian, he is professional and communicates promptly.”
