Personal Statement

I specialize in the surgical treatment of esophageal and gastrointestinal disorders including GERD, achalasia, esophageal cancer, and gastric cancer. I have advanced training in minimally invasive laparoscopic and robotic surgery. I also perform many general surgery procedures including cholecystectomy (gallbladder removal) and hernia repair (hiatal, inguinal, paraesophageal and ventral).
