I am privileged to have achieved my lifelong goal of becoming a pediatric gastroenterologist, more specifically a pediatric neurogastroenterologist. I have a special interest and expertise in disorders of the gut-brain interaction, including motility disorders, which involve the movement of food through the GI tract, and functional disorders, which involve interactions between the brain and GI tract that affect motility. These conditions can be debilitating and yet they remain challenging to treat effectively. My team and I evaluate and treat children and adolescents using advanced, state-of-the-art diagnostic and therapeutic techniques with multidisciplinary approach. Some of the conditions we treat are dysphagia, achalasia, gastroesophageal reflux disease, chronic nausea, gastroparesis, irritable bowel syndrome, chronic abdominal pain, severe constipation, fecal incontinence, and anorectal disorders. We think of our patients and their problems holistically and take pride in developing personal connections with patients and their families. My goal is to deliver compassionate, respectful, evidence-based, and humanistic care to children with gastrointestinal diseases. I co-direct many multidisciplinary clinics, including the Gastrointestinal Motility Center, Esophageal Atresia Clinic, Aerodigestive Program, and Congenital Diaphragmatic Hernia Program, and I work closely with pediatric surgeons, pulmonologists, cardiologists, ear nose throat (ENT) specialists, psychologists, and language pathologists to provide the most comprehensive care to children with complex GI medical conditions. I also take great pride in educating medical students, residents, fellows, and other providers. I have mentored several GI fellows who have joined other institutions across the county and are currently working to establish multidisciplinary clinics and expand access to care for functional and motility disorders. In addition to my clinical and education roles, my team and I conduct multiple clinical research projects focusing on functional and motility disorders. I work on clinical trials which allow our patients to have access to therapeutics that are not otherwise offered to children. This work has led to numerous presentations at national meetings and publications in high impact gastroenterology journals—all with the mission of improving children’s health and advancing the science of gastrointestinal motility and functional gastrointestinal diseases.

After working for several years as a general pediatrician, I pursued specialized training in both pediatric sleep medicine and pediatric pulmonology. Experience in these three areas helps me understand how the entire body, particularly the respiratory system, is affected by a child’s sleep...

Dr. DiLorenzo is a board-certified pediatric cardiologist and Assistant Professor of Pediatrics at Columbia University Irving Medical Center. He specializes in non-invasive imaging within the division of Pediatric Cardiology. He received a Bachelor of Arts from Columbia University and his medical degree from New York University (NYU) School of Medicine. He completed his residency training at the Children’s Hospital at Montefiore in the Bronx, NY prior to completing his pediatric cardiology fellowship and subspecialty training in non-invasive imaging at the Children’s Hospital of Philadelphia. During that time, he received a T32 research training grant and earned a Master of Science in Clinical Epidemiology (MSCE) at Perelman School of Medicine at the University of Pennsylvania. Dr. DiLorenzo specializes in non-invasive imaging, including cardiac magnetic resonance imaging and transthoracic and transesophageal echocardiography. He is also co-director of the Pediatric Comprehensive Marfan Clinic. His research interests include non-invasive markers of right ventricular structure and function in patients with congenital heart disease.
