Our Services
Comprehensive Digestive and Liver Care
From general gastroenterology to specialized liver screening, weight management, and concierge level care, MacArthur Gastroenterology offers a full range of services designed around your health goals.
General Care
Gastroenterology
Our core practice covers the full spectrum of digestive health, from routine colon cancer screening colonoscopies to the diagnosis and treatment of conditions such as GERD, IBS, IBD, and hepatitis. Dr. Peterson and our care team bring decades of experience to every visit, with a preventive approach that focuses on catching and managing issues early.
See Your Primary Care Physician for a Referral
MacArthur Gastroenterology accepts new patients by physician referral. If you are experiencing digestive or liver related symptoms, ask your primary care physician for a referral to our office, and our team will take it from there.
Physician Supervised Program
Weight Management
A personalized, physician supervised program combining medical evaluation, nutrition coaching, progress tracking, and compounded GLP-1 support when clinically appropriate, provided in clinic and never shipped.
MASLD / Fatty Liver
Liver Scanning
A fast, non invasive ultrasound based scan that measures liver fat and stiffness in minutes, with no needles, no sedation, and results the same day. Early detection matters, since the earliest stages of fatty liver disease are often reversible.
Personalized Care
Concierge Medicine
For patients who want a higher level of access and personal attention, our concierge medicine program offers extended visit times, priority scheduling, and direct access to your physician for ongoing questions and care coordination.
