Dr Hallos graduated from King’s College, London in 1981.
He has gained extensive experience working in general dental practice, initially in Southern England, followed by a period in private practice in New Zealand and then a number of years in the Shetland Isles.
Dr Hallos subsequently worked for several years in the Outer Hebrides where, alongside practice, he taught undergraduate dental students from the University of Aberdeen and undergraduate therapy students from the University of the Highlands and Islands. He followed this by working for some time with the British Military.
In 2014 Dr Hallos decided to concentrate on a career long interest in endodontics and commenced an MSc on the subject at King’s College in London. He completed this in 2017 and now limits his practice to the discipline.
Dr Hallos is based at Vermilion’s Kelso clinic and treats patients referred for endodontic treatment.
