Practice Manager

Katie Gemmell is our Practice Manager. She is responsible for the day-to-day management of the practice ensuring we deliver care to our patients in an efficient and effective way.


Please note we are currently a full time Practice Nurse down so please bear with us as the stretched nurse team tried to maintain an good service across both surgery sites.

Our practice nurses see patients by appointment only. They all undertake general treatment room duties, are involved in national screening programmes (Cervical Smears) as well as chronic disease management with routine hypertensive and chronic kidney disease reviews.

They can offer advice on numerous health topics including asthma, hayfever,  diabetes, and heart disease prevention, well woman/man checks, family planning and HRT.

It is possible to request a telephone call from the practice nurse, depending on when the request comes in you will be contacted either the same day or the following day, please try to give a landline telephone number.

All our Registered Nurses are experienced and most have been with us for many years. They all run routine Practice Nurse Surgeries and they have all undertaken extended training and specialise in certain areas.
