Johann  Peterson

Johann Peterson welcomes LGBT patients.

Philosophy of Care

I enjoy the company of children and I like to see them happy. I know that GI problems can have a huge impact on a child’s quality of life. I chose gastroenterology as a field because I find it satisfying to address the diagnostic challenges using basic physiology and to find a treatment strategy that is compatible with my patient’s preferences.

Clinical Interests

I take care of patients with a range of gastrointestinal, nutritional and liver disorders including inflammatory bowel disease, infections, liver disease, functional gastrointestinal disorders and motility problems, feeding and nutritional difficulties.

My research has been in the development and function of the enteric nervous system.
