I went to Jack, having heard about the power of his work from friends. While I had minor health issues that I was hoping to work on, my main goal was to have my energy systems tuned up so that it would be possible for me to climb Mt. Olympus with my children and grandchildren after a summer in which I had not managed to do any training for this very strenuous (almost 10,000′ and about 14 miles round trip) hike. Since our goal was to scatter my husband’s ashes on the peaks, it was important to me to be physically present at the top. I don’t really understand what it is that Jack does, but it works. I felt stronger after each of my three sessions, and when we got to Greece, was able to complete the climb in just one day rather than the two days necessary when I was younger.Jack, you are a miracle-worker! And my grandchildren think that their ‘Oma’ is a superwoman. I will certainly be back for more tune-ups.
