I have had the pleasure of knowing Dr. Kharrazian for more than a decade and observing his professional growth and impact as a key opinion leader in the field of Functional Neurology. He is voracious in his pursuit of learning and skill development. His pursuit of post-graduate studies at Harvard in research methods has embellished his already significant expertise in systems medicine and its application to Functional Medicine. He has a unique skill in making complex information accessible to his students and patients alike which is a measure of an individual who is a master of his field. Dr. Kharrazian is a humble, quietly competent leader who leads by example and his presence. The Functional Medicine field is rapidly evolving, and it is through the work and leadership of a select group of professionals of which Dr. Kharrazian is a recognized leader that it is growing in both its adoption and successful application to the treatment of complex chronic diseases. It is truly a pleasure to call Dr. Kharrazian both a colleague and friend in our mutual advocacy in the development and application of Functional Medicine.

Dr. Datis Kharrazian is one of the top thought leaders within integrative and functional medicine. His passion for research and evidence-based medicine shines through in his writings as well as his lectures and educational programs. The clarity of his thinking and his integrity has led curriculum leaders at Harvard Medical School, Loma Linda University School of Medicine, and Bastyr University California to bring him to their institutions. His willingness to share his knowledge has endeared him to our graduates at the Institute for Functional Medicine (IFM) and to me as one of the founders of the educational programs at IFM. He is a mainstay of our IFM faculty.

When I first heard Dr. Kharrazian speak about a decade ago, I went up to him at the podium and asserted “You are the next Jeff Bland!” His deep understanding of the material, excellent review of the research and expert communication skills are very, very impressive. Since then, I have made a point of always attending his lectures at conference, reading his insightful research articles and seeking his insights when studying challenging issues, especially in the area of environmental medicine.

My practice has been greatly influenced by Dr. Kharrazian’s education. I gained the knowledge and confidence to be able to take on complicated chronic cases. I would not be able to have the success that I have with my patients without the information I gain from Dr. Kharrazian.One of the great things about Dr. Kharrazian’s teaching style is that he wants you to be able to take the information you learn at the seminar on Saturday and Sunday and apply it in practice on Monday. I have taken many seminars by many different doctors. Often the material is presented in such a way that you have to find time to study what you learned in order to apply it in practice. Dr. Kharrazian will take a topic and give an overview. He will then dive deep into the information and present the details and research. He will then follow that up with the take away points, clinical pearls, and explain how to immediately implement the information into practice.

I started out in practice as a straight chiropractor and using basic nutrition as an adjunct therapy. I had a desire to help my patients more than I was already helping them. I felt that I needed to further my education in the area of nutrition. I started attending many different seminars but nothing really clicked for me. The education was basic, anecdotal, and scientifically unsound. A friend of mine invited me to one of Dr. Kharrazian’s seminars back in 2006. It was at that point my practice was changed forever. Because of the education I received from Dr. Kharrazian, today I have a successful functional medicine practice filled with complicated, chronic patients. I could not do what I do without the knowledge I have gained from Dr. Kharrazian.

So many in this field of study and education know that the body is a gorgeously integrated system.  Dr. Datis Kharrazian, however, has a level of understanding and commitment to this magnificent science that many of us deeply respect and secretly envy.  Accessing his teachings is a privilege.

I’ve had the pleasure of knowing and working with Dr. Kharrazian for many years and have repeatedly been amazed at his ability to fearlessly think outside of the box.  His intensely creative mind allows him to explore entirely new avenues of understanding about how we become ill and what it takes to get well again.  Dr. Albert Szent-Gyorgyi, Nobel Prize winner and one of the forerunners of Functional Medicine, has been quoted as saying that “Research is seeing what everybody else has seen, and thinking what nobody has thought.”  As the quintessential clinician-researcher, Dr. Kharrazian is clearly following in Dr. Szent-Gyorgi’s footsteps.

Dr. Kharrazian is one of those people who when you first hear him speak, you realize something refreshingly special is happening. What I mean is, he can take complex, evidence-based material from research and break it down to practical application with a clarity rarely experienced! I have had the honor of teaching Functional Medicine with Datis at Loma Linda University School of Medicine for the past 5 years where I have witnessed first hand Dr. Kharrazian stir intrigue and critical thinking in the minds of budding physicians. The legacy of root cause medicine is served best when practitioners like Dr. Kharrazian are willing to dig deep in the evidence and ask the hard questions as to why things are and why it matters. This movement needs the humble confidence that is evident in the service Datis gives to his colleagues, students, and community each day.

I first met Dr. Kharrazian when he was a student in my class. I was impressed with how bright he was and knew back then that he would make a significant impact as a practicing clinician. I just did not realize how much of an impact he would have in shaping today’s paradigm shift in whole-person systems-based medicine. A classic example of “the student has become the master” and then some. A triple threat as a successful clinician, researcher, and educator, Dr. Kharrazian’s contributions have earned him a reputation as an international leader in lifestyle and functional medicine.

Dr. Kharrazian’s educational seminars are extremely practical. The science is presented in a logical fashion and can be quickly assimilated to any practice the next day. My practice has realized a surge of much healthier and happier patients who were given alternative treatment options to mainstream pharmaceutical models. The growth of new patients was noted as well. I have been able to immediately implement the protocols of treatment discussed at the seminars. Since attending Dr. Kharrazians seminars and viewing his webinars my practice took a much more integrative approach to illness. I rarely use pharmaceutical prescription medications and found that patients are thankful to be given choices. I found the education to be top notch, ahead of most conventional medical educational programs. All protocols are supported by old as well as current research. The presented information is supported with so much research, in fact, that any attendee will be at ease adapting the treatment models to any practice.

I have known and worked with Dr. Kharrazian for more than a decade. During this time, I have seen him change the landscape of healthcare with how we evaluate and care for patients. His persistence to gain knowledge and disseminate information to the public is one of his greatest strengths. His ability to integrate functional medicine, immunology and neurology is second to none. He has been a pioneer in holistic health and has been teaching practitioners how to more effectively care for their patients. Through his best-selling books, educational seminars, presentations, clinical work, and being adjunct faculty, he has impacted lives far reaching. Individuals like Dr. Datis Kharrazian come around once in a lifetime. I could not be more honored to learn from Dr. Kharrazian and consider him to be a wonderful mentor. I sincerely believe that the Kharrazian Institute will continue to evolve health care.

Dr. Datis Kharrazian is one of the original pioneers of holistic medicine. His groundbreaking work set the stage for many advances in integrative medicine. There is no researcher in the world more qualified than Dr. Kharrazian to provide the most accurate and reliable health information, based on his research and extensive clinical experience with complex patients. For years he has been guiding people to solve their thyroid and brain issues when no one else could help them. I trust all the content that he has made available and will continue to follow with interest his ongoing discoveries.

Through almost forty years of medical conferences I’ve found only a handful of speakers, scientists, educators who can adapt their innovative research and thinking to the clinical pearls we hope to take away for Monday morning. Dr. Kharrazian is one of them. His lectures are compelling and clinically valuable, filling in some of the voids left behind in our traditional medical education. I leave his presentations with more synaptic connections than I came in with. First and foremost though, every patient I treat benefits from Dr. Kharrazian’s knowledge and teaching.

I have learned from Dr Kharrazian for years and have admired his determined ability to research and correlate information into relatively easy clinical applications for the big picture. He takes you from details to the big picture in a stirring way that yields confidence and direction as a practitioner. One of the things I admire the most about Dr Kharrazian is his level of integrity and his open willingness to share. I have never seen him do anything but choose the best for the educational benefit of any practitioner and patient. Integrity is the only option for Dr Kharrazian. My practice has made huge growth and changes over time due to the educational gains I have learned and been able to apply for the benefit of the patient. This has allowed me to see difficult cases getting no results elsewhere. Additionally, my patients sense and feel my clarity to the extent they are very compliant to all instructions I give them. They see the difference in the applications.

Dr. Datis Kharrazian is one of the most brilliant people I have met. He pursues education at the most prestigious universities and uses the knowledge acquired there to improve the lives of his patients, including those with autoimmune diseases, brain issues, hormonal problems such as thyroid disorders, and many others. Dr. Kharrazian is not only able to get to the root of the problem and help heal the patient, but he does so with compassion. A truly unique person!

I had the pleasure of meeting Datis Kharrazian in the early 2000’s. At this time in my practice I already was board certified in clinical nutrition and board eligible as a chiropractic neurologist. I have been practicing for 38 years and may I say currently the greatest influence in my current format of patient care comes from the mentorship of Datis Kharrazian. Implimentation is the key to successful patient management and Datis always supplies that immediate available algorithm. It is rare to find a format that addresses the neuro endocine immune axis so completely. My frustration in my neurology training was finally validated when I met Datis, and continues to grow as I follow my friend Datis. We all should strive to continue to learn and Datis continues to be a beacon of excellence in his career. Thank you Dr Kharrazian for all you do.

Dr. Kharazzian’s teachings have made more of a difference for helping my patients than anything else I’ve studied. I’m a Medical Doctor Board Certified in Integrative Medicine; I’ve completed the IFM certification courses, a Preventive Medicine Residency, plus I’m currently completing the Fellowship in Anti-Aging Metabolic and Functional Medicine modules. Of course, I’ve learned from all these studies. Yet, Dr. Kharrazian’s way of explaining things has been the most clear and relevant for helping both myself and my patients best understand the underlying causes and interactions involved with complicated multi-system illnesses. His treatment recommendations are the most efficient and effective game changers for my chronic patients who have suffered for years without finding help. Working now with the UC Irvine Integrative Health Institute, our team is excited to be able to start training students from the Schools of Medicine, Nursing, Pharmacy, and Allied Health. Dr. Kharrazian’s educational materials will continue to be a significant part of my practice. I’m thankful beyond words for all he’s contributed to both my personal health and my professional growth.
