My passion for nursing as well as providing a great standard of care began at a very young age. After completing two years of a BSc Hons degree in General Nursing I decided to further explore the Dental Sector. Shortly after starting my role as a Trainee Dental Nurse at St. Martins I knew I had made the right decision. With the support of all the staff, I have learnt so many new skills as I am sure I will continue to do so throughout my time here. I feel very privileged to be part of such an amazing team.

My spare time is spent with family and friends, as well as going for long countryside walks with our dog Meg.
