Dr. Koganski specializes in prevention, diagnosis and treatment of complex and chronic medical conditions. His practice is dedicated to the comprehensive treatment of the whole patient by incorporating the latest advances in traditional medicine, combined with various holistic and integrative modalities to address the unique concerns of each patient. No single approach is right for all physical/mental conditions. Dr. Koganski combines conventional and functional medicine, using nutrition, exercise, emotional health, acupuncture, bio puncture, homeopathy, herbal supplements and biofeedback therapies as needed, to restore the long-term health and vitality of each individual.

Dr. Koganski offers a Concierge Membership Program to his patients, which enables him to devote more time to each patient’s comprehensive care, giving them 24/7 access directly to him, focusing on functional medicine evaluations, in-depth genetic testing, nutritional and health coaching to achieve true wellness. The Functional Medicine approach is not covered by insurance, but it is included in Dr. Koganski’s Concierge Program or available on a fee for service basis.

Dr. Koganski is a member of the International Evidence Based Longevity Group, comprised of physicians and scientists dedicated to extending our healthy lifespan.  NIM offers a Longevity Program, designed to provide early diagnosis of age-related changes in your body, including early signs of potential disorders, then provide you with guidance on how to improve or reverse these changes to extend your healthspan and lifespan.  The Longevity Program is an optional service and is not covered by insurance.

As a dual board-certified physician in Internal Medicine and Functional Medicine, as well as a member of the International Evidence Based Longevity Group, I’m here to help you Start Your Journey to Better Health Today!
