Andrea Mackenzie at the British International School of Houston

Learning Support Teacher

After gaining my bachelor's degree in Applied Psychology from Durham University, I embarked on a PGCE at Newcastle University.  For a number of years, I taught in mainstream schools in the north-east of England and held lead positions in ICT and mathematics.  I joined BIS Houston in 2019/2020 as part of the Learning Support Team.  My years of experience have taught me the value of patience and encouragement.  I work closely with each student, providing the individualised support and praise they require.  I like to make sure I stay connected with family members and any specialists involved, to encourage the success of each student, in and outside of the classroom.  I've truly appreciated and learned from every student and every family I have worked with;  I cannot imagine having any other job!  

My husband works within the oil and gas industry so the opportunity to relocate to Texas arose in 2013 - we have never looked back!  We are parents to three fabulous children; my son, Ewan and twin girls, Alexandra and Charlotte.  As a family, we enjoy everything the wider Houston area has to offer!  I like to attend gym classes as often as my busy schedule allows - I love spinning!
