Born and raised in New York, on the North Shores of Long Island, Jacqui developed a passion for science, health and nutrition, initially becoming a Registered Dietitian after graduating from the University of Connecticut, Storrs, CT.  As a dietitian working in many different arenas, and after she obtained her Masters degree in Nutrition at James Madison University, Harrisonburg, Virginia, she increasingly became interested in medicine, especially it’s connection with diet and nutrition.  Realizing that her life passion was to enable people to learn as much as possible about their health and how they can optimize it, she pursued a career change after learning about the role of and the significant impact that Physician Assistants have as healthcare providers.  After graduating from New York City’s Weill- Cornell Physician Assistant Masters program in 2010, she initially worked in Surgical Intensive Care and Critical Care at St. Francis Hospital Heart Center.  Due to a desire for continuity of care and to see patients on an ongoing basis, she accepted a position as a PA at Weill Cornell Gastroenterology in NYC, with a focus on liver diseases.  To broaden her gastroenterology experience, she moved on to accept a PA position with Winthrop University Hospital, Mineola, NY (later to become NYU-Long Island Hospital).  Working with a large physician academic practice, Jacqui provided services for patients with a wide range of needs including Crohns, Ulcerative Colitis, Gastroesophageal Reflux Disease, Barrett’s Esophagus, Irritable Bowel Syndrome, SIBO, Colorectal Screening, Rectal bleeding, Gastrointestinal Malignancies, Diverticulitis, Fatty Liver (NASH), Liver, Biliary and Pancreatic diseases, including Autoimmune diseases and Exocrine Pancreatic Insufficiency, Achalasia, Gastroparesis and other Motility Disorders such as Chronic Idiopathic Constipation.  Jacqui and her husband (along with her 2 year old black lab, Boone!), driven by their love of being outdoors, doing anything water related and desire to live in a culturally diverse and nature-enriched environment, have relocated to the Big Island of Hawaii permanently to be a part of the community, both personally and professionally.  Call Ali’i Health Center to schedule your prompt consultation with PA Gould for your gastroenterology and  GI-related nutrition needs.
