“I believe it is important for patients to understand the distinct differences between my skills and experience as a double boarded colon and rectal surgeon versus other medical professionals involved with the diagnosis and treatment of GI disorders. Years of rigorous training with both the endoscopic treatment of colonic disease but also the surgical management of colonic disease, is truly what sets my practice apart. Being able to take care of my patients through both aspects of care is not only rewarding as a physician, but also a significant benefit to the patient in terms of a comprehensive approach to their care.”
