Biography

Dr. Ludwig is a member of the Colorectal Surgery team. This team is comprised of surgeons, nurses and support staff who specialize in the diagnosis and treatment of benign and malignant diseases of the colon, rectum, and anus. They work closely with colleagues in Surgical Oncology, Gastroenterology, Medical Oncology, and Radiation Oncology to ensure that patients get the very finest medical and surgical care for the full range of benign and malignant colorectal disorders.


The Colorectal Surgery team is committed to providing outstanding and compassionate care to patients with colorectal diseases. The team believes that this type of care comes from the intense dedication and specialization of the staff to specific colorectal disease processes and that coordinating efforts with their medical and surgical colleagues ensures patients get the best multidisciplinary care available.

Dr. Ludwig and team are active in research and widely cited in academic publications regarding colorectal cancer and benign colorectal conditions.
