Current Intern: Dr Matthew Gaskell

As part of our commitment to training and supporting the next generation of rural doctors, GMC hosts Intern doctors under the Junior Doctor Training and Innovation Fund. These doctors have completed their medical studies in the previous 12 months and have provisional registration. You may be offered an appointment to see our current Intern using what we call “wave consulting”. This means you will see the Intern doctor who will listen to your concerns, assess you and develop a plan of management with you. You will then be joined by the supervising doctor, generally your usual GP, who will ensure you are happy with the plan and complete any further actions you may need. Our Intern doctors also assist us with audit and research projects.
