#13 - James Geering
James Geering is host of the Behind The Shield Podcast.  "I was born in England and spent almost thirty years there before emigrating to the U.S.  My early years saw me in in a spectrum of jobs from lifeguard to stuntman.  I had always dreamed of becoming a Firefighter but was told as a child that my poor color vision would disqualify me from the process.  It wasn't until I moved to America that I realized that the vision deficit was mild and was a poor excuse for not following my dream.  I promptly enrolled in the Fire Academy and the rest is history.  I have been a Firefighter/Paramedic for fifteen years now and still love it as much as my first day on the job.  I am also a Crossfit coach and a graduate from the University of Florida with a Bachelor's in Exercise Physiology and Kinesiology. At the start of my firefighting career I felt invincible and thought that the only danger to my health would be in a collapse or burn over.  As the years have progressed, I began to notice a trend of ill health in my profession.  Retirees would pass away soon after they left.  Young firemen got fatal illnesses and depression claimed the lives of many of my brothers and sisters.  I incurred several injuries on the job despite being a lifelong athlete, realizing that my training was creating some glaring weaknesses.  I started on a path of self reflection and ultimately healing, which took me to some of the greatest minds in the wellness world.  Through questioning everything I had been taught, I began to deconstruct the entire fitness community and rebuild from the ground up.  I realized that there was a giant void in the area of First Responder wellness.  The advice and literature that was out there seemed outdated and disconnected from the rigors of shift life.    There was only one solution; fill that void with the amazing knowledge I had encountered along my own journey of repair." - James Geering

#11 - Rick Strassman
Rick Strassman MD performed the first new human studies with psychedelic drugs in the US in over 20 years. His research involved the powerful naturally-occurring compound, DMT – N,N-dimethyltryptamine.

He wrote about this research in the popular book, DMT: The Spirit Molecule, which has sold over 100,000 copies, has been translated into 12 languages, and is now available as an audio-book.

Dr. Tommy John owns and runs the Dr. Tommy John Performance and Healing Center in San Diego and is the author of “Minimize Injury, Maximize Performance: A Sports Parent’s Survival Guide.” Tommy was drawn to chiropractic because he realized there was a higher element missing from the healing, performance process and proper function of the human body in the innate intelligence and the nervous system: brain, brain stem and spinal cord.  That paramount observation led him to obtain his Doctor of Chiropractic Degree from Life University, (a 4-year program), in Marietta, Georgia, where he graduated Magna Cum Laude.  As the son of renowned Major League Baseball pitcher Tommy John who played in the Major Leagues for 26 seasons and was the first person to comeback in 1974 from the revolutionary surgery named the Tommy John Surgery, it is not surprising that Dr. Tommy developed a passion for proper healing and physical function as he witnessed firsthand the outcomes of injury, innovation and principled healing. The primary goal of Dr. Tommy John Performance and Healing Center is to provide entire families with integrative, individualized care plans and treatment to improve their quality of life by reducing physical and emotional pain from injury and aging and minimizing the use of pharmaceuticals or surgery.

Dr. Jeff Volek is a registered dietitian and professor in the Department of Human Sciences at the Ohio State University.  For the last two decades, he has performed cutting edge research elucidating how humans adapt to diets restricted in carbohydrate with a dual focus on clinical and performance applications. His work has contributed to the existing robust science of ketones and ketogenic diets, their use as a therapeutic tool to manage insulin resistance, plus their emerging potential to augment human performance and resiliency. This research indicates that that well formulated ketogenic diets result in substantial improvements in insulin resistance and the myriad of cardio-metabolic biomarkers associated with metabolic syndrome, including favorable changes in fatty acid composition and saturated fat metabolism, cholesterol and lipoprotein profiles.
