Dr. Neiblum has been a practicing, board-certified gastroenterologist for 28 years, and is the senior partner of a large GI practice in a Philadelphia suburb. He is a fellow of the American College of Gastroenterology, the American Gastroenterological Association, and the American College of Physicians, and has personally performed over 25,000 endoscopic procedures, including diagnostic and therapeutic colonoscopy, upper endoscopy, and PEG feeding tube placements. He is an expert on current practice guidelines including colonoscopy screening guidelines and appropriate intervals for both high risk (such as those with a family history of cancer, or those with Ulcerative colitis) and average risk patients.

Dr Neiblum is also an expert on appropriateness of endoscopic and imaging procedures for particular patient complaints, and when such procedures are NOT indicated. In addition, he is an expert on treatment of acute pancreatitis, including fluid management of such patients, GI bleeding, and whether colonoscopy complications have breached the standard of care.

Dr Neiblum usually answers all emails and phone calls within 4 hours, and can usually complete chart reviews within a short period of time; he is responsive to all attorney phone calls and schedule constraints. He has been named a Top Doc in Main Line Today, and in Philadelphia Magazine and Castle Connolly Top Doctors for the last 9 years. He has reviewed dozens of legal cases for medical malpractice, both for the plaintiff and defense, and has performed GI-focused IME exams as well for insurance claim cases.
