Dr. Dana D. Portenier

I am from Rockford, IL and I'm a general surgeon. I always thought I would be a cancer doctor but never a surgeon. It turns out I enjoyed operating. I enjoy the immediate gratification of surgical treatment whether it's removing an appendix, or fixing an incarcerated hernia. I love Durham, NC as does my wife and two children. We look forward to staying here for a very long time and being a part of this community. Dr. Fong is rated as an Advanced provider by MediFind in Gallbladder Removal. His top areas of expertise are Cholecystitis, Gallbladder Disease, End-Stage Renal Disease (ESRD), Gallbladder Removal, and Hernia Surgery.

My clinical interests include gastrointestinal surgery, with a focus on gallbladder and gastric disease, reflux disease, and hernias. Additionally, I enjoy working with patients to decide the best treatment for weight loss that will resolve diseases, such as diabetes and hypertension. The most satisfying part of my job is when patients are proud of their success and recognize their ability to accomplish their goals. I was raised in upstate NY, attended Boston College, and spent three years working in Colorado prior to starting medical school in Arizona. I received advanced specialty training in weight loss surgery and endoscopic treatment of reflux disease at Duke in 2014. I enjoy spending my spare time outdoors. Dr. Seymour is rated as an Advanced provider by MediFind in Gallbladder Removal. Her top areas of expertise are Obesity, Hernia, Gallbladder Disease, Gallbladder Removal, and Endoscopy.

I came to Duke from Nebraska, where I was a medical director for two weight loss surgery programs. I decided to become a weight loss surgeon because it gives me the chance to establish a long-term relationship with my patients. For many patients, weight loss surgery often feels like a fresh start, since they are able to get rid of some of the health problems they may have acquired due to their weight and do certain activities they couldn’t do before. I get a thrill out of being able help patients start this “new life.” My approach to care involves listening to what the patient wants out of the surgery, educating them about various treatment options and performing a full evaluation. Then, I work with the patient to come up with a treatment plan that meets their physical and mental health needs. Dr. Sudan is rated as an Advanced provider by MediFind in Gallbladder Removal.
