Dr. Carlos Marois is an experienced urologist based in Quebec and the founder of Les Cliniques Marois, a network of private urology clinics serving the South Shore (St-Hubert), Laval, and Quebec City.

Board‑certified since 1998, he transitioned exclusively to private practice in 2017 after nearly two decades in major hospital centres, including 17 years as Head of Urology at Hôpital de Verdun. Dr. Marois is a pioneer in minimally invasive and endoscopic urologic surgery. His experience spans advanced open surgery, laser procedures, endoscopic interventions, and specialized male and female incontinence surgeries, including urinary artificial sphincters.
