Hi – My name is Lara and I’m a professional nanny with over 6 years of experience caring for children from infants to pre-teens. I’m CPR certified, bilingual in English and Portuguese, and passionate about creating safe, nurturing, and fun environments where kids can thrive. I’ve worked with families in Woodside, Menlo Park, Redwood City, and Portola Valley, providing everything from daily care to overnight stays while parents travel. My responsibilities have included driving to and from school, organizing playdates, helping with homework, preparing healthy meals, and planning creative activities. I love supporting children’s emotional growth, encouraging independence, and making each day both safe and enjoyable. I can also assist with light household tasks and am happy to provide great references from the families I’ve worked with.

I have a degree in Psychology from UFRJ (Universidade Federal do Rio de Janeiro), in Brazil. When I first came to the U.S.(96) I was a stay at home mom. my kids were 7 and 2. I've been working with kids (other than mine) since 2003. I have been serving and helping families with children ranging in ages from 4 months to 6 years old. I think it's fun and very rewarding to see any child grow, and I'm happy and proud to be a part of a child's development, as well as give parents a helping hand in their journey of raising their children.
