Overview

I care for patients seeking long-term, sustainable weight loss through advanced surgical options. As a bariatric and minimally invasive surgeon, I specialize in procedures such as sleeve gastrectomy, gastric bypass, and revision surgeries. I also address related conditions like hernias, reflux, and metabolic disease. I’m passionate about supporting patients not just during surgery, but throughout their journey—before, during, and long after the procedure. I chose this field because I’ve seen how life-changing these interventions can be, both physically and emotionally. I take time to understand each patient’s goals, challenges, and lifestyle, and I work with them to build a path forward that’s realistic and durable. Outside of work, I enjoy travel, music, and time with friends, which helps me stay grounded and energized for the work I do.

A significant portion of my practice involves advanced minimally invasive techniques in thoracic surgery to treat diseases such as lung or esophageal cancer. Another part of my clinical practice is spent taking care of patients with severe lung disease, especially those needing lung transplantation. Patients from all over the world come to Duke for lung transplantation. Research demonstrates that experience is very important in taking care of complex medical problems, both on the surgical side and on the medical side. We have one of the largest transplant centers in the world with excellent survival statistics, as well as the shortest wait list time. Instead of the national average which may be four to six months, our patients wait an average of about two weeks. One of the best aspects of being a patient or working at Duke is the people who work here. No matter how challenging the medical problems may be or what problems may arise, I know there’s a world’s expert a phone call away who can help intervene and I know that my patients will be cared for by committed Duke staff from across the hospital.

His top areas of expertise are Gastroesophageal Reflux Disease (GERD), Hiatal Hernia, Esophageal Cancer, Lung Transplant, and Endoscopy.

The majority of my practice focuses on abdominal wall surgery and the repair of ventral, incisional, and inguinal (groin) hernias. I chose to specialize in minimally invasive surgery because I saw the incredible benefits that these procedures provide for patients. By performing complex surgeries using either laparoscopic or robotic instruments, I am able to get patients back to their normal daily activities much faster and with significantly less pain. Whether I am repairing a hernia, performing surgery for weight loss, or helping to treat reflux, I will always try to offer a minimally invasive approach first and foremost. When I get the chance to meet you in the clinic we will discuss all of the possible treatment options for your condition and we will work as a team to pick which is the best choice for you. I feel incredibly fortunate to practice at Duke Health where we have incredible resources to take care of you no matter what problem you may have. I look forward to working with you and caring for you and your family. Dr. Greenberg is rated as a Distinguished provider by MediFind in the treatment of Achalasia. His top areas of expertise are Hernia, Umbilical Hernia, Obesity, Gastric Bypass, and Endoscopy.
