Dr. Mariella Ferreyra

MD, CCFP, MSc - Medical Director & Physician

Dr. Ferreyra had a unique beginning to her career in medicine in Peru as an emergency response physician with the fire department, as well as providing care in Internal Medicine, Paediatrics, Surgery, and Gynaecology-Obstetrics wards at a hospital in San Pablo. She then returned to Canada to complete a Masters in Epidemiology where her thesis was based on immigrant health and health care experience. This provided her valuable insight into various health care needs in immigrant populations and how to best address them in her practice.

Dr. Ferreyra completed her Family Medicine Residency at the University of Ottawa. She has been involved in clinical healthcare research at both Toronto Western Hospital and the University of Ottawa. For the past five years Dr. Ferreyra has been a family physician at One Healthcare Center in Ajax, Ontario. She loves to encourage patients to adopt healthy lifestyles to improve their overall quality of life. This can involve reshaping work-life balance, or looking after ourselves the way look after the ones we love.

Dr. Ferreyra believes that the “one-size-fits-all” approach rarely helps to achieve this and she aims to identify tailored solutions to help patients live their lives to the fullest.
