As an accomplished clinical psychologist registered with the College of Psychologists of Ontario, Dr. Firestone has settled into her true passion over the past 13 years, working exclusively in private practice in her home town of Ottawa. She is a warm and collaborative psychologist who is highly effective at helping people make changes to their lives. Although she works with a variety of mental health issues, she is best known for her treatment of anxiety, mood, and eating disorders. Dr. Firestone loves her work and is motivated to keep up with the latest developments in clinical practice so that she can provide the best possible service to her clients. 

Dr. Firestone has published in scientific journals, received several awards for her research, taught university courses and given various talks over the course of her career. Outside of work, Dr. Firestone keeps busy with plenty of sports, reading, travel and adventure, but mostly by enjoying time with her young family.
