Ballinger has led clients up Everest, Manaslu, Lhotse, Ama Dablam, Cho Oyu, and Makalu. During the 2010 climbing season on Mt. Everest, Ballinger summited the mountain twice in three weeks, first on May 5 and then again on May 22. On his May 5 summit, Ballinger was the first non-Sherpa of the season to summit as he fixed ropes, replaced anchors, and removed old ropes from the mountain in partnership with 9 Sherpa. Also in 2010, Ballinger led an Alpenglow Expeditions Clean Up Expedition on Ama Dablam. This team, along with climbing the mountain, removed thousands of feet of old fixed rope from the route, along with hundreds of pounds of trash from the camps. They also provided outreach to Sherpa and members of other climbing teams to teach the use of human waste disposal kits while on the mountain, and donated human waste disposal bags to many of those teams. In 2011, he repeated his feat of summiting Everest twice (May 5 and May 20) in only a few weeks and added his first summit of Lhotse (May 26) to that schedule as well. Ballinger has led successful expeditions to more than 25 Himalayan summits over 6000 meters, including twelve ascents of Ama Dablam, which is a highly technical 6800m peak next to Everest. Since 2007, he has guided clients to the summit of Everest 6 times, Manaslu 4 times, and Cho Oyu and Lhotse once each. He has also led an expedition to Makalu, the world's fifth tallest peak.
