About Us

Since July 2016 Castle Square Clinic has been under ownership by Nia Hughes-Jones who took over the practice from Mr and Mrs Humphreys. Nia and her team look forward to welcoming patients old and new, continuing to provide an exemplary dental service.

For our patients comfort, we have a large flat screen television and a wide up-to-date magazine selection in our modern reception area. Our surgeries are also equipped with the latest technology and have lovely views of the harbour and Caernarfon square.

At present due to the existing layout, our B listed premises surgeries are not accessible to wheelchair users and we are unable to provide a disabled toilet.

Our Team regularly attend training courses to keep up to date with the latest developments in dentistry to deliver a highly professional service.

Below you can find pictures and profiles of the team at Castle Square Clinic.
