Dr. Sanjaya K. Satapathy is the medical director of the Center for Liver Disease and Transplantation at the Northwell Transplant Institute, program director of Northwell's Transplant Hepatology Fellowship, and professor of medicine at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell.His path to medicine began in India, where he was inspired by his father an engineer with a passion for homeopathy to pursue a career in healthcare. He earned his medical degree from Veer Surendra Sai Medical College, followed by fellowship training in gastroenterology and hepatology in the early 2000s. During that time, he witnessed the profound need for liver transplantation in India, where access remained scarce.While presenting his research at a conference in the United States, Dr. Satapathy was drawn to the opportunities and possibilities for advancing transplantation in America. He decided to continue his career in the United States, completing additional residency and fellowship training before serving as a transplant hepatologist in Memphis. In 2019, he was recruited to Northwell.It was a dream to begin from zero and build a transplant program that could be a model not just for the area or the state, but for the country, says Dr. Satapathy. Within only a few years, we've been able to achieve that goal, because Northwell has all the elements and resources to be one of the best programs in the nation. The expertise we have is unparalleled, with a collaborative team that encompasses all levels of care.The program was founded just in time for a huge surge in demand for liver transplants in the area, he adds. Liver disease and other liver issues are on the rise, making the need for an extensive program crucial for those in the New York region. Part of the program's strength is innovation. For example, Northwell is utilizing an approach that allows donated organs to be safely preserved for a longer period of time, which means needed organs can travel longer distances even from as far away as Hawaii. Northwell is also running several clinical trials on transplant medications and operates a robust transplant hepatology fellowship program to train the next generation of doctors a program Dr. Satapathy launched.I'm passionate about this work, and particularly about my patients, he says.
