Philosophy of Care

It is my goal to provide the best, evidence driven care for your child. I will spend time with you and listen to gain an understanding of your child's medical experience. Then, working together with you, your family, and if needed, with other medical professionals, I will devise a plan for optimal care. If that involves procedures for your child, it is my priority to keep your child as comfortable as possible.

In addition, I believe in treating the child holistically. Often, the child has been experiencing GI issues for a prolonged period of time and this can have mental and emotional impacts. It is important for me to address psychological needs in conjunction with the GI issues.

Clinical Interests

Dr. Hassan is a pediatric gastroenterologist specialized in neurogastrointestinal motility. Her clinical interests include swallowing disorders, gastroesophageal reflux, small intestinal bacterial overgrowth, irritable bowel syndrome, constipation, and Hirschsprung’s Diasease. She has clinical expertise in managing patients in multidisciplinary settings and has had an active role in aerodigestive and colorectal centers in former institutions.

Research/Academic Interests

Dr. Hassan's research interests include swallowing disorders and constipation. Her past research focused on diagnostic techniques in eosinophilic esophagitis, specifically in measuring esophageal compliance and correlating that to symptoms and molecular markers of inflammation. She has also been involved in studying how virtual reality modules on diaphragmatic breathing can help treat functional constipation.
