Dr. Singh’s passion for medicine and healthcare equality led him to pursue a Master in Public Health in addition to his Medical Degree. He strongly believes in treating a patient as a whole, not just the disease. This involves being very detail oriented and patient — meticulously considering the patient’s circumstances and surroundings and communicating effectively with the family.

“Input from all caregivers is very important to a child’s care — to understand the complete picture and implement treatments effectively.”

It is also important to Dr. Singh to speak directly to and connect with his young patients. “Children are incredibly smart and impressionable. My treatment plans often include therapies that address diet and lifestyle, and these work best when you reach the child at their level.”

Dr. Singh treats numerous diseases that affect the digestive tract, including inflammatory bowel disease, eosinophilic esophagitis and failure to thrive, with a special focus on celiac disease. “Early detection and treatment of celiac disease are key to optimize a child’s growth potential, avoid nutritional deficiencies, allow faster intestinal healing, as well as reduce the risk of other autoimmune conditions from developing.”

In addition to his clinical practice, Dr. Singh also routinely performs endoscopies, which enable him to directly visualize the digestive tract to help with accurate diagnosis and implement local treatments.

He is also involved in numerous research initiatives aimed at furthering our understanding of celiac disease and developing new therapies for his patients. “We are increasingly unraveling the role of the human genome and microbiome in digestive conditions. The large patient base we serve at CHOP and our commitment to research put us at the forefront of medical breakthroughs, and I am so excited to be a part of it.”
