Gastroenterology South - Newberg





About
Where quality care is the "scope" of our practice
At The Oregon Clinic Gastroenterology South, we strive to make your visit with us as quick and caring as possible. Each step along the way through your treatment, you can count on fine, personalized outpatient care from our specialized and highly-skilled medical, nursing, and support staff.
Once you have your appointment, please arrive at least 15 minutes early, and bring your referral forms (if required), insurance information and co-payments. We will automatically request your medical information from your primary care provider before your visit. When you schedule, please let us know if you’ve had any relevant x-rays, ultrasounds or other imaging studies.
Medical emergencies may cause unexpected delays in our schedule. Your patience and understanding are appreciated. If you must cancel or reschedule your appointment, please call us as soon as possible.
Since November 2014, each of our three gastroenterology groups has been participating in the GI Quality Improvement Consortium (GIQuIC) program. Being part of this organization requires a focus on enhancing patient care through real-time peer-based performance evaluation. Click to read more on the GIQuIC website.
