About me

Dr. Trad is a fellowship-trained, board-certified surgeon with more than 25 years’ experience. He specializes in treating conditions that affect the abdominal wall and gastrointestinal tract, including gastroesophageal reflux disease (GERD), hiatal and paraesophageal hernias, gastrointestinal stromal tumors (GIST), gallbladder disease, ventral, incisional, inguinal, and femoral hernias and recurrences.

His areas of special expertise include robotic repair of hiatal hernias, paraesophageal hernias, and totally intrathoracic stomach (a condition related to hiatal hernia where part of the stomach protrudes through a hole into the diaphragm), robotic resection of GISTs, robotic gall bladder removal, robotic repair of ventral, incisional, inguinal, and femoral hernias.

Dr. Trad’s philosophy of care is simple--the best way to care for patients is to care about patients. He believes in providing the highest quality surgical care and only operates when it is truly indicated.

Dr. Trad is an active researcher and has served as principal investigator on numerous trials. He has been widely published in peer-reviewed journals including Surgical Endoscopy, Gastroenterology, and Endoscopy. He also has been an invited lecturer and presented at national and international conferences and meetings.

When he’s not working, Dr. Trad enjoys spending time with his six children, traveling, sailing, and skiing.

Dr. Trad is fluent in English, French, and Arabic.
