Overview

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.

I went into medicine with a desire to care for individuals of all backgrounds and to help address disparities in health care. Being a surgeon gives me the opportunity to diagnose and treat the individual while my background in public health helps me to focus on preventative care for my patients. I am a general surgeon who cares for emergency and elective general surgery patients. My training in minimally invasive surgery and surgical endoscopy allows me to care for my patients in the least invasive manner possible in order to minimize patient discomfort and improve patient recovery. I aim to perform procedures laparoscopically (with small incisions) or endoscopically (without any incisions). As a surgeon, I aim to provide an open and inclusive clinical environment by listening to and caring for patients of all different races, religions, sexual orientations, and backgrounds. Dr. Fathalizadeh is rated as an Experienced provider by MediFind in the treatment of Gastroparesis. Her top areas of expertise are Hernia, Gastroparesis, Ogilvie Syndrome, Ileostomy, and Gastrectomy.

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 Gastroparesis. His top areas of expertise are Hernia, Umbilical Hernia, Obesity, Gastric Bypass, and Endoscopy.
