Dr. Brian J. Fertig

Dr. Brian J. Fertig is an endocrinologist in Piscataway, New Jersey. He is also a passionate writer, researcher, teacher and speaker. He is currently writing a book tentatively titled “Metabolism and the Future of Medicine”. The book targets a moderately technical audience but seeks a broad range of reader including clinical physicians. From that book will be synthesized a shorter and easily understandable text for the general public.

Dr. Fertig has consultation privileges with several area hospitals, including JFK Medical Center in Edison, NJ and Robert Wood Johnson University Hospitals in New Brunswick and Rahway, NJ. In practice for more than 20 years, Dr. Fertig is highly regarded for his expertise in endocrinology, diabetes and metabolism.

Dr. Fertig places special emphasis on using an interdisciplinary approach to biological problem solving in clinical medicine. Dr. Fertig is a highly sought-after speaker on the local and national stage. He has delivered well over 100 lectures on diabetes, endocrinology and metabolism to his peer physicians and endocrinologists.

Dr. Fertig is president of the Diabetes and Osteoporosis Center of Central New Jersey, which he founded in 1995. He is also the Chairman of the Department of Endocrinology, Diabetes and Metabolism at JFK Medical Center and an Assistant Professor at Robert Wood Johnson University Medical Center.

Dr. Brian J. Fertig has always been a leader in his field. He served as a fourth-year administrative and teaching chief medical resident at Englewood Medical Center as a joint program with The Mount Sinai Medical School in New York City, and served there as a Clinical Instructor. During that time, he earned the Chief Resident Award, and the longstanding co-chairman of the Department of Medicine at Englewood Medical Center wrote that Fertig was one of the best chief medical residents in recent memory.

Along with his mentor at the University of Pennsylvania, Seth Braunstein, Diabetes Section Chairman, Dr. Fertig initiated a clinic dedicated to cardiac transplant patients with steroid induced or exacerbated diabetes. Written during his time at the university, he was subsequently credited as the first author of the Therapy of Diabetes chapter in the textbook Diabetes in America. Senior authors of the chapter were Don Martin and David Simmons. Published in 1995, this textbook, sponsored by the NIH (National Institute of Health), became the most-referenced book regarding the standard of care for diabetes.

Dr. Brian Fertig has enjoyed the privilege of working with world-renowned mentors and experts in metabolic bone disease, neuroendocrinology, thyroid disorders, and pituitary diseases.
