Dr Daniel Goodare, 42, is an accident and emergency and acute medical doctor at the Galloway Community Hospital in Stranraer.
An experienced GP, he states he has seen first-hand the challenges facing the NHS as a result of cuts in public spending in recent years.
Dr Goodare is a specialist in remote medicine and also provides specialist care across the country and internationally.
He formerly worked in Dumfries and Galloway Royal Infirmary and as a doctor across the globe, including in the Calais refugee camp, Antarctica and Kazakhstan.
Dr Goodare lives in Twynholm, Kirkcudbright with his wife and their six children.
His wife is the chairwoman of the parent council at Kirkcudbright Academy and enjoys reading and hill-walking in their spare time.
Following his selection this week, Dr Goodare said: “I’m not a politician and I’ve never stood for election before.
“But working as a doctor has given me a great insight into the current state of our public services like our NHS.
“It is that insight which has worried me enough to put my career aside and step up to the mark to fight for the very future of those services.”
Dr Goodare added: “I joined the Labour Party many years ago because I saw decent people who want to make society, fairer and kinder and stronger.”
