I provide the full spectrum of digestive care to children of all ages, from babies with reflux and feeding problems, to school-aged children with abdominal pain and constipation, to adolescents with irritable bowel syndrome, to children with celiac disease, food allergies, and inflammatory bowel disease. I also have special expertise in the gastrointestinal manifestations of cystic fibrosis; I completed the Cystic Fibrosis Foundation’s Developing Innovative GastroEnterology Specialty Training (DIGEST) Program, and serve as the gastroenterology representative on the Program Planning Committee for the North American Cystic Fibrosis Conference. My primary practice is located in Stamford, Connecticut, where I see patients in the office and perform procedures such as endoscopies and colonoscopies. I see patients with cystic fibrosis at both the Northern Manhattan Columbia campus and in Stamford. I value working closely with families and their pediatricians, as well as other subspecialists, to provide compassionate and coordinated care for my patients, and really enjoy serving the families of Fairfield and Westchester counties and beyond. As the director of fellowship training for the Department of Pediatrics, I am very involved in graduate medical education. I am not only the director of the Pediatric Gastroenterology Fellowship Training Program at Columbia, but I also oversee all of the fellowship programs in the department. As director, I established the Pediatric Fellows’ Academy, a shared curriculum that promotes the professional development of pediatric fellows. I have been involved in many educational initiatives for pediatric residents and gastroenterology fellows through the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN). I am currently Vice-Chair of NASPGHAN’s Training Committee and recently served as the co-chair of NASPGHAN’s Teaching and Tomorrow program for pediatric residents interested in specializing in gastroenterology. I am also the editor of PREP® GI, a peer-reviewed online education program administered by the American Academy of Pediatrics.

John F. Ciannella, MD, is a fellowship-trained and board-certified neonatologist who since 2008 cares for newborn infants and those who are premature or diagnosed with complex medical and rare conditions and those who are critically ill. Dr. Ciannella oversees the care and development of newborns and premature babies, diagnosing congenital conditions such as airway birth defects, kidney defects, lung development conditions and other complex conditions. He utilizes advanced technologies and new pharmaceutical therapies to improve survival and quality of life. Dr. Ciannella also treats neonatal emergencies that arise either during or after birth and those who are transported to the hospital or transferred from other hospitals. He is an expert in treating the most-high risk, complex newborns, including those born premature. Dr. Ciannella is committed to excellence in patient and family-centered care and is compassionate about each patient he serves – providing comfort and support at an extremely stressful time. As Director of Neonatology, Dr. Ciannella led an initiative to include more physician assistants and neonatal nurse practitioners within the neonatal intensive care unit (NICU) team. This expanded team allows newborns to receive comprehensive, coordinated care by a team of experts trained in numerous specialties. During his free time, Dr. Ciannella enjoys staying active through sports, exercise and outdoor activities with his family and friends.

Dr. Harvinder Sandhu specializes in minimally invasive spine surgery, endoscopic spine surgery, microsurgery, computer-assisted surgery, and the study and use of spinal biologics. He completed his training in spinal surgery at UCLA Medical Center in Los Angeles, California and was subsequently Chief of the Spinal Surgery Service at UCLA until 1997. At that time he was recruited to join the staff at Hospital for Special Surgery. Dr. Sandhu has more than 75 peer reviewed scientific publications in areas such as biologic enhancement of spinal surgery and novel minimally invasive management of spinal disorders. He has received research awards from the North American Spine Society, the Orthopaedic Research Society, and the International Society for the Study of the Lumbar Spine, including the prestigious Volvo Award in Spinal Research. In addition to clinical practice, Dr. Sandhu is actively engaged in the research, development, and invention of a variety of medical devices and instruments used in spinal surgery. He holds several patents involving the diagnosis and treatment of spinal disorders.
