Dr. Matthew Hartwig

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.

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.
