Dr John Tan is a Paediatric Allergist and Immunologist based in Chatswood. He works out of Chatswood Specialist Centre, Suite 109, 63A Archer Street, Chatswood NSW 2067.
For families, his clinic is mostly about helping kids feel better and cope with health issues that can be hard to manage at home. Many appointments are for allergy problems in children, including common skin and food-related reactions. At times, kids also come in with ongoing breathing issues linked to allergies, so asthma management can be part of the plan as well.
Dr Tan can help with allergy testing for children. He also looks at food sensitivities in kids, where parents want clear, practical guidance. Getting answers is often the main goal, but so is making a plan that fits real life. That can mean figuring out what to watch for, what to avoid (when needed), and what steps to take if symptoms flare up.
Immunisation is another key part of his work. He provides consultation for immunisation shots for kids, helping families understand what to expect and how to stay on track. For many parents, having one place to ask questions about both allergies and childhood health makes things feel less stressful.
He is trained in paediatric allergy and immune care, and this shows in the way he talks through options. Conversations stay calm and clear, with simple next steps. Over time, he helps families see the bigger picture—how triggers, symptoms, and treatment fit together. At appointments, he focuses on the child first, while making space for parents to ask the questions they’ve been holding onto.
Dr Tan communicates in English, as well as Chinese (Cantonese) and Chinese (Mandarin). This helps many local families feel more comfortable and supported when they’re explaining symptoms, routines, and day-to-day concerns.
