Siobháin Keenan-Maciejewska

I am originally from Ireland and I was educated in my beautiful home town at Trinity College, Dublin where I gained a B.Sc. in Speech and Language Therapy, subsequently completing a Post Graduate Certificate in Early Years Care and Education through Froebel College as well as a TEFL Certificate for early learners in Dublin School of English, as I had bitten the travel bug but wanted to be able to work with young children wherever I landed. 

When I initially qualified, I worked in both hospital and community-based settings in Dublin as a paediatric speech and language therapist with children who had been born prematurely or with developmental delays or disorders. Having made Polish connections during my time in University, I decided to visit my friends (one of whom later became my husband), to study Polish and take up a post in early years in Piaseczno, Poland in an English-language preschool. I planned on returning home to hospital-based work, but in 2004, I was offered a post in Nursery here at The British School and I have been here ever since, caring for and educating TBS children for twelve consecutive years in Early Years as a Pre Nursery or Nursery teacher and from 2016, as a Reception teacher. 

Privately, I am married with two children of my own who attend TBS Primary school. I spend most of my free time with my family and friends, getting to know Sadyba and Wilanow as we have recently moved here ourselves from the other side of the city. One of my major hobbies over the years has been learning Polish and I am now fluent in the language, gaining certificates from the University of Pécs, Hungary in Polish at both intermediate and advanced levels. A little-known fact about me is that I am also a breastfeeding consultant, having completed certification as an IBCLC (International Board Certified Lactaction Consultant) from 2010 to 2012, helping me keep in touch with my roots in allied health.

Having regained the study bug through IBCLC, and with my own children that little bit older, I returned to university recently, firstly as a distance learner at The University of Nottingham, UK, completing a PGCE in 2014-15 which enables me to teach throughout primary school and then in 2015-16, to Birmingham City University as a distance speech and language therapist, updating my skills through a "Return to Practice" course.

Highest Quality Learning

For me, Highest Quality Learning means giving every child within my care the opportunity to achieve to the highest level possible for them individually. This means that I need to get to know each child inside and out, in every area of development, assessing his/her progress across every area of learning, ensuring that each and every one of them is enabled to make personal progress beyond that which would ordinarily have been expected. This is probably the main reason I love working in Early Years as through the EYFS curriculum and the observations carried out within it's framework, I can truly focus on each area of each and every child's development.
