While studying and working in different part-time positions as a laboratory technician, a zoo keeper and pet store employee, she created a program of animal support to help adults with mental disabilities.

In her free time, she likes doing yoga and she likes to participate in Social Justice groups, especially volunteering in Food banks such as Community Service and helping local new immigrants. She is always busy and on the go but can always stop to ask people if they need help. She speaks Spanish, Hebrew, Portuguese and English, all with an accent and a smile!
