Mark's body of work explores leaning into life and holding nothing back. Mark is a poet and philosopher who has taught in the fields of poetry, spirituality, and health for over thirty years. In 1987, Mark was diagnosed with a rare form of lymphoma. The heart of that journey and its aftermath has greatly informed his work. His books and teachings are deep yet accessible because his wisdom is that of one whose close brush with death has enabled a rich understanding of the power of the human soul. He does not discount our flaws, our failings, our human weaknesses.
As a cancer survivor, Mark devotes his writing and teaching to the journey of inner transformation and the life of relationship. A New York Times #1 bestselling author, he has published twelve books and recorded six audio projects. His work has been translated into 18 languages including French, Portuguese, Japanese, and Danish.
