Specialist Orthodontist

I am an experienced Specialist Orthodontist on the General Dental Council's Specialist register providing Orthodontic treatment for adults and children. Orthodontics is my passion! My passion for orthodontics stems from my innate desire to empower others by improving their smiles and restoring their self-esteem. I take pride in taking every patient on a journey of creating a personal treatment plan to suit their individual needs and lifestyle. With discreet Invisalign treatments you will gain confidence and improve your well-being hand in hand. We use the latest technology and listen carefully to what our patients would like to achieve to create beautiful smiles.

Our exceptionally high level of customer satisfaction is what sets us apart.

We only use the most advanced technology and techniques to deliver the highest quality of care for our patients. This involves using digital smile design and intra-oral digital scanning in order to ensure our patients receive the best results.

I have always had a special interest in the discreet methods of the Invisalign treatment.

With more than 20 years experience in orthodontics, I look after patients of all ages from children to adults with the Invisalign system. However as we specialise in Orthodontics and braces, we also offer all typed of fixed braces including Incognito Gold Lingual appliances, as well as orthopaedic removable appliances. We are excellent with nervous patients, always displaying a gentle manner and a calm approach. Our dedicated, professional team is waiting to make you smile with the most comfortable, effective, clear and removable orthodontic appliance, customized and especially designed for you!
