I have a patient focused approach that begins with detailed discussion regarding symptoms. I am regarded by my peers as an excellent diagnostician, and frequently perform second opinion work. I have been named every year as one of Nashville's top doctors by Nashville Lifestyle magazine and most recently by US News and World Report. I am a leader in the community with regards to education where I coordinate an annual gastroenterology and colorectal surgery course at Saint Thomas hospital. I am well published, including a review article in the New England Journal of Medicine regarding the management of irritable bowel syndrome. I am a leader in new techniques including endoscopic mucosa resection, which can remove flat polyps, tumors and even superficial cancers, preventing the need for invasive surgery. I am the Tennessee leader in endoscopic ultrasound, with the largest experience (over 15,000 procedures), and a referral base throughout Tennessee and surrounding states. Most of all I am a caring person and good listener.
