My name is Mr Millar, and I am delighted to introduce myself as your child’s Head of Year 7 for the 2026/2027 academic year. I am excited to meet all of you.

I have nearly 22 years of teaching experience across various schools in Hertfordshire and London. I have a strong passion for Sports, Teaching and being outdoors! I am excited to share the knowledge I have gained over the years as a teacher, coach and a player to the future generations of OSA students.

I have two boys, the oldest is still in Year 7, so I have recently been in your shoes as a parent. I know that there is a range of emotions that you and your child will be going through and the smoother the transition the easier it is for everyone at home. My goal is to work with you to create a supportive team that together can try and ensure a smooth and successful transition for our students. With dedicated teachers, extra-curricular activities and an inclusive atmosphere we will provide our students with the Opportunity, Success and Ambition they need to thrive at OSA and beyond.

I look forward to meeting you and embarking on this journey together.

Mr S Millar
Head of Year 7
