Jana Din Medical Shaman, Tao Center for Healing

Jana Din, along with her husband, John Lee, co-founded the Tao Center for Healing. Jana’s personal interest in holistic healing began in 1985, when she observed how powerfully John’s healing work assisted her mother with colon cancer.  It was during this time that Jana fully embraced health and wellness as resulting from a balanced mind, body, spirit and soul. Subsequently, she began studying  and eventually teaching with author Carol Ritberger, Ph.D., in her four year medical intuitive training programs. Concurrently, Jana also began a six year apprenticeship with a shamanic healer.

Furthering her training as a healer, she traveled to Nepal to receive teachings from Aama Bombo, one of the 13 International Council of Grandmothers. In 2005, Jana began conducting shamanic healing sessions, assisting her clients, which include people such as physicians, nurses and other medical clinicians, healing practitioners, educators, counselors, therapists, attorneys, and business owners, with healing their deepest core soul level issues. In 2013, Jana also began providing volunteer shamanic healing services in collaboration with Dr. David Steinhorn for his critically or terminally ill, or injured pediatric ICU patients. The shamanic
healing support and collaboration between Jana and Dr. Steinhorn was featured in a nationally broadcast TV show, Healing Quest, in a segment titled, “Shamans in the ICU.”  Shamans in the ICU  See bio below.

Prior to doing healing work, Jana began her gratifying career as a dedicated high school teacher with an emphasis in health, wellness, and nutrition. Her understanding of holistic healing further complemented her teaching of these subjects. In 2011, she was selected to represent her school district as Teacher of the Year.  As a lifelong educator, Jana teaches holistic health workshops and brings internationally known healers to conduct healing sessions at the Tao Center for Healing.

James Nestor Author of The New York Times bestseller ‘The Power of Breath’

There’s a secret to solving workplace stress and burn out. It’s surprisingly simple: breathe. According to science journalist James Nestor, breathing is the key to transforming our lives—more than diet, sleep, or exercise. Drawing on his instant New York Times bestseller Breath—which spent 18 weeks on the bestseller list in its first year and has sold over 1.5 million copies worldwide—James teaches us that even slight adjustments to our breathing can profoundly improve workplace efficiency, athletic performance, anxiety, and sleep. Elizabeth Gilbert, author of Eat Pray Love, calls James’ work “A fascinating scientific, cultural, spiritual, and evolutionary history of the way humans breathe—and how we’ve all been doing it wrong for a long, long time.”

When we consider our health and well-being, we scrutinize the foods we eat or the amount of stress we’re under. Rarely, if ever, do we consider the ways we breathe—yet acclaimed science journalist James Nestor says that poor breathing habits are linked to a laundry list of chronic health problems and roadblocks to success: lost focus and concentration, anxiety, sleep issues, and even cavities and crooked teeth. James shows how we’ve lost the art of breathing properly, and teaches us how to get it back again.

In his landmark book Breath: The New Science of a Lost Art, James seeks out what went wrong and shows us how to fix it with a mix of science, humor, history, and simple, constructive takeaways. You’ll never breathe the same again. Brilliantly researched and utterly fascinating, Breath has earned praise from New York Times bestselling author Joshua Foer, who calls it a “transformative book that changes how you think about your body and mind.” Breath became an instant New York Times, Wall Street JournalLos Angeles Times, and London Sunday Times bestseller, and will soon be translated into 35 languages. It was awarded the Best General Nonfiction Book of the Year by the American Society of Journalists and Authors.

James has spoken about the importance of proper breathing at the Stanford Medical School, the United Nations, and Global Classroom (World Health Organization+UNICEF), as well as more than 60 radio and television shows, including Fresh Air with Terry Gross, ABC’s Nightline, CBS Morning News, and dozens of NPR programs. To date, he has written for publications such as Scientific American, the New York Times, The Atlantic, and the San Francisco Chronicle, to name a few.

In his earlier book, DEEP: Freediving, Renegade Science, and What The Ocean Tells Us about Ourselves, James follows extreme athletes, adventurers, and scientists as they explore the ocean, uncovering weird and wondrous discoveries that redefine our understanding of both the ocean and ourselves. The book was a Finalist for the PEN American Center Best Sports Book of the Year, a New York Times Book Review Editor’s Choice, a BBC Book of the Week, and an Amazon Best Science Book of the year.

James has also teamed up with National Geographic Explorer and marine scientist David Gruber to create Project CETI—an ambitious undertaking to help us connect with and better understand the animals we share the planet with. Using technologies like machine learning and artificial intelligence, Project CETI hopes to one day crack interspecies communication, and was accepted as a TED Audacious Project.

Dr. Katherine Amato Biology Professor/ Researcher, Northwestern University 

Dr. Amato is a biological anthropologist at Northwestern University studying the influence of gut microbes on host ecology and evolution. Her research examines how changes in the gut microbiota impact host nutrition, energetics, and health. She uses non-human primates as models for studying host-gut microbe interactions in selective environments and for providing comparative insight into the evolution of the human gut microbiota. Her main foci are understanding how the gut microbiome may buffer hosts during periods of nutritional stress and how the gut microbiome programs normal inter-specific differences in host metabolism. 

In this realm, she is also interested in global variation in the human gut microbiome and its implications for local human adaptation. Dr. Amato obtained her A.B. in Biology from Dartmouth College and her Ph.D. in Ecology, Evolution and Conservation Biology from the University of Illinois at Urbana-Champaign. She completed a postdoc at the University of Colorado Boulder. She is now an Associate Professor in the Department of Anthropology at Northwestern University. She is also affiliated with the Interdisciplinary Biological Sciences Graduate Program and sits on the Executive Committee of the Northwestern Institute on Complex Systems. Dr. Amato is the President of the Midwest Primate Interest Group, an Associate Editor at Microbiome, an Editorial Board member at Folia Primatologica, and a Fellow for the Canadian Institute of Advanced Research’s ‘Humans and the Microbiome’ Program.
