Prior to climbing Everest, Romero had already climbed five of the seven highest peaks in the world in his desire to scale the tallest peaks on the seven continents (counting two for Oceania). He finished the seven summits with Mt. Vinson in Antarctica at age 15. Before climbing Everest, Romero's highest peak was Mount Aconcagua, in elevation. His group chose a northern route out of Tibet and carried a GPS tracking device and satellite phone. Along the way to the top, Romero conducted an interview from an intermediate base camp 18,700 feet above sea level. Upon reaching Mount Everest's summit, a Skype interview was accomplished and Romero also called his mother, who had been following the climb on a map which included GPS coordinates, pictures and video.
