Dr. Angela Merlo


Angela Merlo, MD is the physician founder and proprietor of the Digestive Health & Nutrition Center established in 1990 in Lawrenceville, New Jersey. Dr. Merlo has provided consultative and interventional Gastroenterology to adults as well as children for over two decades.


Dr. Merlo's reputation for excellence is based on: her extraordinary knowledge; her technical competence; and her highly personalized care. She provides individual attention to every patient and takes pride in delivering uncompromising personal care. She does not sell products at her Digestive Health & Nutrition Center. Rather, she employs non-invasive or minimally invasive techniques when appropriate, and interventional endoscopy and colonoscopy when necessary, to lead her to the most accurate diagnosis. She utilizes her expertise to then embark on the most effective treatment plan that combines the best of modern technology with personal nutrition. Dr. Merlo goes beyond traditional endoscopic procedures and provides nutritional recommendations aimed at controlling specific digestive disorders and digestive enzyme deficiencies often without the need for medications.
