About Dr. Samuel Davidoff, MD
Board-Certified Gastroenterologist and Hepatologist
Philosophy of Care
“I believe in treating the whole person, not just the condition. My goal is to find root causes, use the least invasive approach possible, and collaborate with each patient to create a clear and effective treatment plan.”
Dr. Samuel Davidoff, MD
That philosophy shapes every aspect of care at this practice. Rather than defaulting to the most aggressive treatment, Dr. Davidoff works through a diagnostic process that respects patient preferences, weighs the evidence, and keeps the path forward as simple as it can reasonably be. When patients understand their condition and feel heard, they follow through with care. That’s not idealism. It’s practical medicine.

Clinical Focus
Colorectal Cancer Screening and Prevention, Colonoscopy is the single most effective tool for preventing colorectal cancer. Dr. Davidoff performs both screening and diagnostic colonoscopies, including endoscopic mucosal resection for large polyps that might otherwise require surgical referral. With decades of experience across thousands of patients, early detection has been a cornerstone of his career.
Upper GI and Esophageal Conditions, For chronic acid reflux, GERD, Barrett’s esophagus, and swallowing difficulties, Dr. Davidoff performs upper endoscopy (EGD) to directly visualize and evaluate the esophagus, stomach, and upper small intestine.
Capsule Endoscopy, Dr. Davidoff uses capsule endoscopy to image the small intestine, areas that standard colonoscopy and upper endoscopy can’t reach. This is particularly valuable for patients with suspected Crohn’s disease, obscure GI bleeding, or unexplained small bowel symptoms.
Inflammatory Bowel Disease, Managing Crohn’s disease and ulcerative colitis requires ongoing clinical judgment. Dr. Davidoff monitors disease activity, adjusts treatment plans over time, and works to keep patients in remission with the least disruptive regimen possible.
Liver Disease and Hepatology, As a hepatologist, Dr. Davidoff diagnoses and manages fatty liver disease (NAFLD/NASH), viral hepatitis, elevated liver enzymes, and cirrhosis. Many liver conditions are silent in early stages. Catching them before complications develop can change outcomes dramatically.
Hemorrhoid Treatment, Dr. Davidoff offers in-office treatment including rubber band ligation and infrared coagulation, performed in the AAAASF-accredited suite without requiring a hospital visit.
