Joel Sprechman BS RYT CC CL CHHC

Joel is an award-winning lead engineer of mission-critical national security and defense systems receiving accolades from the US Department of Justice. He is a former Ulcerative Colitis patient, current Crohn’s patient, Integrative Nutritionist, biohacker, health and patient advocate, and healing-path pioneer. After conventional and alternative medicine methodologies were unable to effectively treat his Inflammatory Bowel Disease he became a medical researcher, health scientist, and treatment engineer driven by a quest to reverse my failing health, and well-being.

Unfortunately, conventional medicine doesn’t offer much beyond synthetic medications and surgery, so he consulted with the best of the best in functional, integrative and natural medicine and also took advanced certification courses to create magic in his microbiome.

Has spent over 1000 hours reading and reviewing medical journal studies and cases studies, consulting with over 1000 Doctors, Scientists, Researchers, Nutritionist, Coaches and even shamans across the globe. He has spent over $300,000 on education and personal development, and over 500 hours in the American, Australian, Mexican and Israeli healthcare system. He has participated in three clinical trials and experimental non-FDA approved treatments.

In 2015 and 2016 he safely reduced and eliminated all IBD medications and lived drug-free. Anger, blame and not taking personal responsibility for a life-changing event changed that.

2017 his Gastroenterologist described what she saw during Colonoscopy as “The worst colon I’ve seen in 40 years of practice”.

He recovered.

In 2018 a Gastroenterologist told him “Joel, your colon is very sick and needs to come out”

In 18 years of having Ulcerative Colitis, he never needed surgery.

Doctor’s say he has an intense case, on the upper end of the bell curve. Despite those circumstances, he is THRIVING today in 2019. So can you!

Some of the Doctors, Researchers, and health practitioner were great, some good, and some simply not aligned with his personal values. He has learned a tremendous amount from each of them.

He loves to share his gifts and learnings with others.

He has fundraised and personally invested thousands of dollars in for a CUREe and volunteered dozens of hours supporting the underserved community and camps for children with IBD.

He is part of the Qu Biologics’ IBD Community Advisory Panel, also a yoga teacher, meditation instructor, and mindset empowerment coach.

He hosted the Crohn’s And Colitis Summit,  created the One Great Gut Collection, has coached hundreds of patients around the world to live a higher quality of life and has been featured on TEDx, KPBS, and numerous health summits and podcasts. His passion for solving tough problems started at a very early age, inspired by his father and college professors. A big part of his drive and determination is hearing how both his parents escaped war-torn Europe during World War II and came to the United States as refugees. His parents’ journey to seek freedom ingrained in him how important personal freedom is including the freedom to make informed medical and lifestyle choices.

In 2019 he founded the One Great Gut Foundation 501c3 nonprofit with tremendous interest from patients, doctors, and researchers.

Daniel Schmachtenberger – Senior Member –  Neurohacker Collective – Evolutionary Philosopher,  Systems Designer, Strategist

Daniel Schmachtenberger

Daniel has a trans-disciplinary science background within a whole systems, complexity, and integral framework. He loves solving seemingly intractable problems by reassessing the foundational data and axioms of a field and then restructuring it from the ground up. He began seriously studying health and neurology when afflicted with neurological and autoimmune illnesses that had no known solutions in either allopathic or complementary medicine. The insights that led to his healing came from developing a new model for understanding physiology and pathology, which he then applied to help many people address various forms of complex illness and optimize their capabilities beyond their previous healthy baselines. Daniel was the academic dean for a college of mind-body medicine and has consulted for many cutting edge integrative doctors and medical clinics to help find novel solutions for complex cases. He created and ran a cutting edge think tank developing complex systems solutions for environmental and social issues, and has directed a transdisciplinary group of scholars on a philosophy of mind project addressing core questions of mind/brain interface and developing an axiomatic reformulation for the epistemology of neuroscience. He has a significant background with and love for nootropics, meditation, depth psychology,  and all effective tools for evolving states and stages of consciousness and evolving the human experience.

Dr. Duc Le MD
Dr. Duke Le One Great GutGraduated from the University of VA with a Bachelor of Science in Field Biology. He studied acupuncture at the Nanjing University of TCM, or Traditional Chinese Medicine.

He is board-certified in Internal Medicine and practiced hospital medicine for 10 years, most recently at Sharp Hospital in San Diego attending critically ill patients. Frustrated by the poor progress many patients have with just managing their chronic disease, he developed a passion for changing the paradigm of disease care. After studying Functional Medicine and Neuro-Linguistic Programming he founded Optimal Change MD. Through root cause analysis, he creates permanent changes in people’s lives. He optimizes daily energy levels, focus all day, and how effortless days flow. In his spare time, he enjoys researching optimal states of human performance and living, running Tough Mudder Warrior Dash races, and fully embracing: “When I take responsibility for everything in my life, I have the power to change everything.”
