Desiree DeSpong, Instructor, Co-Founder, LET Training Institute


In 1994 our first company was founded to explore the merits of electronic energy medicine after our son, Nathan Dunn, survived childhood cancer. He is now in his 30s. Our time and experience at St. Jude's Children's Research Hospital, and the friendships with other families, gave us our passion for working with health modalities and creating a company that people could trust.


Since 1998 and the creation of our current company, we have evolved therapeutic technology systems focused on the lymphatic system. We pioneered the therapy with thousands of holistic practitioners and home users. They embraced it and gave us valuable feedback on its many applications for health and healing. Today, we are helping cancer survivors all over the world with the side and after effects of cancer treatments. Breast cancer patients have been particularly vocal in their praise. Our clients now include hospital lymphedema departments, integrative medical clinics and clinical researchers, through our sister company ArcStar Med. We support our products with educational seminars through the LET Training Institute, now offering CEU credits for massage therapists and others. We encourage you to contact us if you have any questions, concerns or would like to participate in any of our programs. Staff and Management.
