Dr. Marcos Bettolli completed his medical studies and earned his Medicinae Doctor degree at the Catholic University of Cordoba, Argentina. He completed his residency in Pediatric Surgery at the Hospital Infantil de la Municipalidad de Cordoba, and obtained his degree of Pediatric Surgeon at the National University of Cordoba, Argentina. In 2004, Dr. Bettolli arrived in Canada as the Clinical Research Fellow with the Children’s Hospital of Eastern Ontario (CHEO) with a scholarship granted from the University of Ottawa.

The focus of his research is in basic science - gastrointestinal dysmotility and Minimally Invasive Surgery (MIS). During his Fellowship of 3 years, he developed two advanced immunostaining histopathology procedures for post-operative and intraoperative assessment of Hirschsprung’s Disease pathology. He was then recruited as Assistant Professor at CHEO.

His career focuses are centered on MIS, chest wall deformities, and teaching. Today, CHEO is recognized as having one of the strongest MIS Pediatric Surgery Programs across Canada and is a referral center for chest wall deformities. In 2012, Dr. Bettolli introduced Bracing Therapy, a non-operative treatment for Pectus Carinatum, to CHEO and the Ottawa region. In the same year, Dr. Bettolli became one of the pioneers in non-invasive correction for Pectus Excavatum. By introducing and prescribing the Eckhart Klobe vacuum bell, Dr. Bettolli has brought CHEO to the forefront as a leader with this alternative treatment.

In 2010, Dr. Bettolli became the educational leader for the Pediatric Surgery undergraduate program at the University of Ottawa. As the educational leader, he is involved in teaching, development, and organization of the Undergraduate Pediatric Surgery curriculum at all levels.

In 2014, he was promoted to Associate Professor at the University of Ottawa and earned his distinction as a Fellow of the Royal College of Surgeons of Canada (FRCSC).
