Our Expedition Doctors


Dr. Joe Keena

Joe works as a GP in Wicklow Town and being involved with Earth’s Edge has been “an absolute pleasure and joy” of Joe’s for many years.  He has stood on the summit of Africa three times and traveled to such far-flung destinations as Stok Kangri in northern India, Elbrus in Russia and Aconcagua in Argentina.

He has always been a keen adventurer and Earth’s Edge has given him the perfect opportunity to marry medicine and travel.

He lives in Greystones, Wicklow with his husband, is a keen runner, swimmer and triathlete and is always looking towards that next big adventure.
