Associations & Accreditations
Integrative Medicine & Longevity Expert
Dr. Primas emphasizes promoting health, preventing illness and raising awareness of disease in our lives rather than merely managing symptoms. He is a firm believer in the WHO definition of health:
Health is a state of complete physical, mental, social and spiritual well-being and not merely the absence of disease or infirmity.
Philosophy & Methodology
Board certified by The American Board of Integrative Holistic Medicine, Dr. Primas blends the best of Western & Eastern medical concepts in preventing and treating illness. His use of both traditional and complementary/integrative/holistic medicine like acupuncture, qigong, exercise and nutrition focus on the whole patient and his/her relation to their environment and specific individual needs. In addition to using traditional medications to treat a variety of maladies, Dr. Primas supplements treatment with natural medications.
The Power of Preventive Medicine
Dr. Primas first realized the power of prevention when he was a resident in internal medicine. He saw that an overwhelming majority of patients were hospitalized because of behavioral and lifestyle choices that were less than optimal due to poor health literacy. This realization was further reinforced after working for many years in the inner cities of New York, Chicago and San Diego working with underserved patients who desperately needed health literacy in the food deserts they were living in. The disparities that exist in all communities need to be addressed by health education especially among young people to establish lifelong healthy behaviors to ultimately reduce the burden of the modern chronic diseases that plague all societies. He is committed to changing the current sick care system to a patient empowered well care system focused on prevention. He believes that starting at the grassroots level, beginning with individual healthcare leads to healthier families, communities and nations, ultimately leading to a healthier planet and markedly decreased healthcare burden and costs. In fact, Dr. Primas’ entire practice is based on prevention. Whether it be prevention of acute illness (including STD/STI prevention) and injury, primary and secondary prevention of chronic disease, travel related disease prevention or aging prevention, Dr. Primas is here to guide you.
Medical Innovation
Dr. Primas is always on the cutting edge of medicine and is now guiding his patients using genomics, epigenetics, methylation testing (aging clock), microbiome analysis and telomere length analysis for a more detailed, personal approach to their health. He firmly believes that this approach not only extends the human lifespan, but significantly improves the quality of one’s life (healthspan). He encourages and supports his patients’ quest for optimal health (health optimization) by guiding them through the myriad of results from their genomic and epigenetic profiles, microbiome and telomere analysis, reviewing their data from personal health tracking devices and apps, and advising them on how to best interpret the data and make it useful and actionable. Dr Primas also incorporates innovative modalities for aging deceleration like NAD+ therapies, fasting/time restricted eating, fasting mimicking diets and senolytic therapies. He also offers stem cell banking for future use.
The Primas Primal Protocol
Dr. Primas practices what he preaches. He believes that physicians should be active role models to improve the lives of patients and ultimately the community as well. While encouraging his patients to live a healthy lifestyle, he exercises daily and eats a nutritionally dense, organic (mostly local) and balanced diet congruent with the ancestral health movement which Dr. Primas has personally seen benefits in many of his patients using the Primas Primal Protocol.
Diet & Exercise
He is also a biohacker and pioneer in the quantified self movement, tracking and using his data to continuously improve and maintain his health. Dr. Primas, in addition to incorporating nutrition and cardiovascular, strength training and flexibility exercises, participates in regular stress reduction by engaging in qigong meditation. To achieve overall health, studies show that the best way to prevent and treat the overwhelming majority of illnesses that plague our communities today is to exercise regularly, eat a nutritionally sound diet, get proper sleep and engage in some form of stress reduction technique.
Travel Medicine
Dr. Primas’ training in travel medicine and tropical diseases has also put him on the forefront of emerging diseases. He has been a media contributor when HIV first arrived as well as SARS, MERS, multidrug resistant tuberculosis, Ebola, Chikungunya, Zika, anthrax, Lyme and now SARS-CoV-2. He was also instrumental in the diagnosing and treating and curing two patients with bubonic plague in 2002 and assisted his hospital in developing protocols for handling level 4 biohazard specimens.
