Dr. Jeffrey Mark, M.D.

With over 30 years of experience, Dr. Mark is a seasoned expert in the field of holistic health and well-being. His life's work is to help patients not only recover their gut health but also enhance their mental clarity, physical vitality, and overall quality of life.

Dr. Mark provides transformative solutions to those who have tirelessly sought answers and remedies for their chronic health concerns, offering them newfound hope, progress and finally resolution.

Dr. Mark's journey in medicine began with a traumatic childhood experience at the age of 10 when he contracted a severe respiratory infection after international travel, leading to a hospital stay where his life hung in the balance due to an incorrect antibiotic prescription. This early ordeal fueled his determination to dedicate his life to medicine and help those in need.

Dr. Mark's outstanding medical education and extensive clinical background exemplify his strong belief in the effectiveness of integrative healthcare. He has a strong foundation in conventional medicine combined with advanced training in functional and regenerative medicine. He earned his BS in Neurophysiology from Northwestern University and pursued medical studies at the University of Illinois College of Medicine. He completed an internal medicine residency at Northwestern and received specialized gastroenterology training at Chicago Medical School. He is also certified in medical acupuncture from UCLA.

In his early 40s, Dr. Mark faced significant health challenges, including fatigue, weight gain, hypertension, and brain fog. Through functional medicine investigations, he uncovered high levels of heavy metal and severe mold toxicity, likely stemming from his work in medically underserved agricultural communities and his consumption of contaminated foods. Drawing on his expertise in functional and regenerative medicine, he developed an effective approach to healing himself.

With a primary focus on gut health as it impacts overall well-being, Dr. Mark has successfully guided countless individuals on transformative journeys to optimal health. His comprehensive methodology integrates tailored dietary plans, specialized supplements, lifestyle adjustments, paired with the strategic use of advanced therapies such as peptides, frequency-specific microcurrent (FSM), PRP, acoustic wave therapy (AWT), exosomes, biocellular therapy, and other anti-aging treatments.

Now in his late 50s, Dr. Mark enjoys the best health of his life, having pursued further training to become 5X Board Certified in Functional Medicine, Anti-aging and Regenerative Medicine, Gastroenterology, Obesity (Metabolic) Medicine, and Internal Medicine. His enduring passion is to empower patients on their health journeys, guiding them toward optimal well-being through his comprehensive, integrative approach.
