About Gregory Nguyenduc, M.D.

“What interests me about gastroenterology and hepatology is caring for patients with digestive diseases that are wide-ranging – from heartburn/reflux and stomach ulcers, to liver diseases such as hepatitis B and C, gallbladder and pancreatic diseases, to intestinal diseases such as celiac sprue (gluten allergy), Crohn’s and colon cancer. I like the balance between a clinical environment and the ability to perform diagnostic and therapeutic procedures such as endoscopy to help diagnose and manage my patients.

“I believe that one of my most important responsibilities is to clearly communicate with my patients regarding their illness. I believe that a patient needs to be aware and educated and therefore involved in their own healthcare. I hope to give my patients quality and compassionate care as a provider with clear communication, understanding and knowledge of their health condition.”

Dr. Nguyenduc is also involved with the Asian Pacific Community in Action ( of Maricopa County regarding hepatitis B education and outreach. In his spare time, he enjoys cycling, tennis and hiking – all spending time with his family.
