Modern medicine relies on teamwork between many kinds of doctors — from family physicians to highly specialized consultants.
Understanding the different types of medical doctors helps patients know where to start, who to see, and how the healthcare system works.
In Canada, the first and most important contact is almost always a family doctor, also known as a primary care physician (PCP).
Family physicians like Dr. Helen Dion at Imagine Health Medical Clinics – Calgary Capitol Hill guide patients through all stages of care — from initial assessment to referrals and long-term follow-up.
