Ellen Kamhi, PhD RN, www.naturalnurse.com, interviews Dr. Sergey Kalitenko. Dr. Sergey Kalitenko has been helping patients throughout a distinguished career – first as an emergency care physician, then as a head of Hyperbaric Department at highly respected Ukrainian hospitals, and later as a board certified physician in the United States. Dr, Kalintenko finds that conventional medicine often treats people, as a collection of symptoms, without finding the cause of those symptoms. His practice is based on the principles of holistic medicine, functional medicine as well as anti-aging principles. Bioidentical hormone replacement therapy is a keystone of his practice. He also specializes in alternative cancer treatment, lyme disease treatment, and intravenous therapy (or IV therapy).He is firmly committed to finding natural solutions to health problems and his first step is to use his expert diagnostic skills to get to the root of the problem. Dr. Kalitenko’s philosophy is that of wellness, not illness.
