My name is Tassia. I'm a Portuguese/ English/ Spanish speaker nanny, 36 years old. I'm looking for one-time job, date night jobs. I have been working with children since I was 15 years old. My specialty is infants and toddlers but I'm also good with teenagers. I'm CPR and First Aid certified. I'm fully vaccinated Covid. Thank you for taking time to read my profile, fell free to send me message. Talk to you soon!

“If the app allows 10 stars rating I would choose that for Tassia! She’s kind, fun, very aware of the surroundings and knows what to do as soon as she stepped foot inside. We knew we can trust her with our kid after the first booking. She’s great with our 4 years old and also newborn. She is also a great artist that my son cannot stop talking about her drawings. If you need someone love the children more than just a job-Tassia is the one! Thank you Tassia!”

I love to engage with children in a safe, positive and joyful manner! Currently I work in a childcare nursery with kids generally between 6 months and 5 years old. I worked at a very busy childcare center in a health club for about 18 years, with children between ages 6 months and 12 years. I look forward to bringing my decades of childcare experience, enthusiasm and joy to my interactions with your child.

“So kind trying to meet Sir Jingles! Would recommend Julie for anyone wanting a kind cat sitter!”

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 I have an outdated first aid and CPR certification but I am almost certain there has not been any significant changes since 2017.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.”

"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!"
