Dentist specialising in Orthodontics

In addition to working in private practice, I also work as an NHS consultant in orthodontic in East Surrey Hospital.

I have always enjoyed working with children and supporting them and their families through treatment, which is way I choose Orthodontics as a speciality. I have vast experience treating nervous and anxious children, and also different types of braces.  I think it is very important to focus on what the patient hopes to achieve with braces. Apart from making sure that you are pleased with your smile when the braces ‘come off’, I strive to ensure that my patients’ journey through treatment is as comfortable as possible.
