His areas of specialty care include surgery of the esophagus and stomach (including surgery for reflux/heartburn, weight loss, achalasia, hiatal hernias, ulcer disease, gastrointestinal stromal tumors, and gastric cancer), surgery of solid organs (spleen, adrenal glands, thyroid, parathyroid, pancreas, and liver), surgery of the abdominal wall and hernia surgery, including complex abdominal wall reconstruction, and colon surgery and colon cancer. Whenever possible, he uses advanced minimally invasive techniques, including robotic, laparoscopic, and endoscopic (incisionless) approaches.
