Office Information and Patient Forms

Services & Programs

Pediatric Aerodigestive Program

The Pediatric Aerodigestive Center provides care for children with complex medical problems involving the airway, lung and the upper gastrointestinal (aerodigestive) tract.  We bring together a multidisciplinary team in a single location to care for your child.

Pediatric Inflammatory Bowel Disease (IBD) Program

We understand that living with IBD as a child or teen can be especially hard, with educational and social stressors to deal with alongside the array of symptoms, including bleeding, frequent stools, cramping, fatigue, and even arthritis.   Our multi-disciplinary approach helps young patients with IBD to manage their disease, so they can continue to live full lives in childhood, adolescence, and beyond.

Pediatric Food Allergy Program

Food allergies or food intolerance can range from mild to severe, and determining the cause can often be challenging.  Our pediatric gastroenterologists specializing in food allergies and intolerances work with a multidisciplinary team of experts who help diagnose young patients and customize a treatment plan for each child.

Pediatric Motility Program

If your child has problems with motility — the coordinated contraction and movement of the digestive tract — we know how much these problems can interfere with your child's and your family's quality of life.  Children can develop motility disorders that range from relatively benign conditions such as constipation to more serious disorders such as Hirschsprung's disease.  Our goals are to find out the reasons for your child's symptoms, and to provide you with an effective, practical treatment or management plan.

Diagnosis & Treatment

Upper and Lower Endoscopy

Endoscopy is a procedure that allows a Gastroenterologist to look at the inside of the gastrointestinal tract using an endoscope. An endoscopy is performed to discover reasons for problems including swallowing difficulties, bleeding, indigestion, abdominal pain, nausea, vomiting, reflux, chest pain or diarrhea.

Capsule Endoscopy

Capsule endoscopy is used to look at the inside lining of the small intestine. Conventional upper endoscopy will only visualize the beginning of the small intestine, and colonoscopy will only visualize the end of small intestine. Capsule endoscopy is a way of bridging that gap to see the entire intestine.

pH Probe Study

A pH probe study is designed to assess acid reflux in your child. Sometimes this study can be performed "with impedance," which means that it will also detect non-acid reflux.
