A Unique Approach to Digestive Care 

Pearl Digestive Health specializes in outpatient endoscopy and colonoscopy in a collaborative setting. Digestive care often overlaps with the specialties available at Pearl including reflux, weight loss, pelvic floor disorders, surgical interventions and chronic pain. We are your Portland resource for expertise in nutrition as it relates to the microbiome/metabolome and health outcomes in digestive health, metabolic syndromes, obesity and women's health by bringing together evidence based science and complementary care.  

We have established a unique "VIP" (very important polyps) screening colonoscopy program with state-of-the-art equipment, the best and easiest colonoscopy preparation regimens, private pre/post procedural care, longer scheduled time for each procedure, unique hydration and microbiome rebalancing . Our quality and data programs ensure only appropriate need for procedures, and an "open access" pathway for both colonoscopy and upper endoscopy provide convenient evaluations in a timely manner.
