Stewart Lonky, M.D.

Dr. Stewart Lonky specializes in pulmonology and is currently affiliated with Cedars-Sinai Marina del Rey Hospital. He has been board-certified in Pulmonary Disease since 1984 and in Internal Medicine since 1974. The physician graduated from the SUNY Downstate Medical Center College of Medicine in 1971 and has been in practice for 50 years. Dr. Stewart Lonky is a member of the American College of Surgeons, the American College of Chest Physicians, the California Lung Association, and the New York Academy of Sciences. He earned a Bachelor's degree in Chemistry from St. Lawrence University before receiving his medical degree, his internship was completed at State University Kings County Hospital, and his residencies were done at Barnes Hospital and the University of California, San Diego. The physician completed his fellowship in Pulmonary Disease and Biochemistry at the National Institutes of Health at the University of California, San Diego. Dr. Stewart Lonky subsequently served for 6 years as a member of the teaching and research faculty at UC San Diego before starting a private practice in 1982.

Prior to practicing in California, he had a medical license for Arizona. The physician's expertise in the area of toxic damage to the lungs made him a sought-after consultant in the area of Toxicology, particularly as it relates to occupational and environmentally induced asthma. He served as a consultant to the State of California from 1986 to 1988 and helped create standards to measure respiratory impairment and disability. This introduction to the clinical world of toxicology piqued Dr. Stewart Lonky's interest in the potential role of antioxidants in protecting the lung and in the role of detoxification in reducing the clinical symptoms in those people exposed to toxic pollutants in the environment. Over the past 10 years, he has been a strong advocate of nutritional approaches to achieving wellness and has served on the medical advisory boards of nutritional companies, reviewing clinical protocols for the study of various products in the treatment and prevention of heart disease, macular degeneration, arthritis, and other ailments.
