John Burke

Co Owner

John got bitten by the CrossFit bug after some training with Trevor and in CrossFit Limerick , his personal goals saw him setting his sights on some big mountains, after previously recording many summits in the Alps, including Mont Blanc, the Matterhorn, and experiencing many technical climbing trips to Scotland on graded snow and ice, as he trained and supported two Everest summitters. John successfully summited Ama Dablam(6812m) in late 2015 and after many years of preparation and training John successfully became the first Clare man ever to Climb the highest mountain in the world and stand atop Mt Everest in May 2017. We look forward to seeing where his next great adventure will take him, but, in the meantime John hopes to bring his experience in business to help promote and grow CrossFit in Ennis and Clare.
