Greg is a 32-year-old Maltese Medical Doctor specialising in Accident and Emergency situations.

His love for the outdoors and adventure has taken him across four continents. From the blistering cold and rarefied air of 7000-metre peaks of the Himalayas and the Andes to the muddy trails of the rain forests of south east Asia and Borneo, from the desolate plains of the Tibetan plateau to the windswept jagged skyline of the FizRoy range in Patagonia.

Among his high altitude peaks there are Mt. Kilimanjaro (5895m, Tanzania), Mera Peak (6476m, Nepal), Balmhorn (3698m, Switzerland) and neighboring peaks (Rinderhorn, Altels etc), Cerro Aconcagua (6962m, Argentina) the highest mountain in the Andes and the highest peak outside Asia, Ojos del Salado (6891m, Chileand Jbel Toubkal (4167m, Morocco).

Greg says that he keeps climbing because, "There is something about mountains which fills me with respect and admiration. There is nothing more awe inspiring than a snow-capped peak and the challenge it presents. My love for the outdoors and travel, the ever present urge to push myself to the limit and then a step beyond contributed to my decision to join this venture. However there is a very fine line between determination and hard-headedness. Crossing that line on an 8000 meter peak will cost you limb or life."

As a medic with pre-hospital and emergency experience Greg's expertise will undoubtedly prove useful during the challenge8000 expeditions.

Over the past year Greg invested considerable time and effort broadening his knowledge in the emerging field of "wilderness medicine" in particular the high altitude aspects of this evolving and developing science.
