Hello my name is Ibolya Ryan.  I am Hungarian, and I was born and raised in Romania.  I was trained as a teacher both in the USA and Europe, and I have worked in four different countries for the last 15 years.  I enjoy learning about other cultures, and as a person I enjoy being with others and tend to be an organizer of those around me.  Also I have high interest in other languages; one of my goals while here in the UAE is to gain some proficiency in Arabic.  
I live in Abu Dhabi with my 10-year-old twin boys and I teach in a big KG school, 35 minutes away from downtown Abu Dhabi. We are one of the NSM (New School Model) schools and we follow the co-teaching model between the Arabic and English teachers.
