Dr Tung Tran
Dr Tung Tran

Dr. Tung Tran is a general surgeon and specialist in bariatric, laparoscopic and upper gastrointestinal surgery. He received his medical degree from McGill University, where he also completed a master’s in epidemiology.

He did an additional fellowship year in laparoscopic and bariatric surgery at Penn State Hershey Medical Center in Pennsylvania before starting his career in bariatric surgery at Medstar Washington Hospital Center in Washington. He returned to Quebec, at the Hôpital de la Cité-de-la-Santé in Laval, in 2016.

“I decided to specialize in bariatric surgery because this surgery has a big impact on patients’ quality of life. Each person has different goals, whether to regain their quality of life or mobility, stop taking medication, or watch their grandchildren grow up. My job is to properly communicate information about their options and work with patients to help them achieve their goals. Patients are extremely grateful to have bariatric surgery.”
