At GMF Clinique médicale Saint-Laurent, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr Grenier frequently works with patients towards goals such as:

• Many seek Dr Grenier's help for their child having a sudden high fever, being very irritable, and not acting like themselves. The collaborative goal is having a clear, actionable, and well-understood plan, along with readily available support from Dr Grenier, for effectively managing an acute flare-up of a chronic condition like Inflammatory Bowel Disease (IBD), Chronic Migraine, or Rheumatoid Arthritis (often in co-management with specialists), allowing a return to valued activities like making consistently informed, conscious, and positive decisions about their daily diet, overall nutrition, optimal hydration, and mindful eating habits for sustained energy and peak physical health.
• It's rewarding for Dr Grenier to see patients with a lingering chesty cough with phlegm that's making them worried about bronchitis achieve receiving a clear, understandable, and timely diagnosis for their persistent health concern, finally bringing peace of mind and a concrete path forward for treatment or management under Dr Grenier's care and return to important activities like confidently and independently taking various modes of public transportation (bus, train, subway) when needed for commuting or leisure, without excessive physical difficulty, navigation challenges, or heightened anxiety about accessibility or safety.

Your personalized healthcare plan, developed in discussion with Dr Grenier, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives. He believes in empowering patients with the knowledge and support needed to take an active role in their health journey.

What exactly is a family doctor (Médecin de famille) and what is their role?

A family doctor, often called a general practitioner (GP), is a medical doctor specializing in comprehensive primary healthcare for individuals and families across all ages and life stages. They serve as your first point of contact for most health concerns, offering preventative care (like check-ups, immunizations, and health screenings), diagnosing and treating acute illnesses (such as infections or minor injuries), managing chronic conditions (like diabetes, hypertension, or asthma), providing mental health support, and coordinating your care by referring you to specialists when necessary. A key aspect of their role is building long-term relationships with patients to promote overall health and well-being.

How can I find a family doctor (Médecin de famille) in QC who is accepting new patients?

Finding a family doctor in Quebec who is accepting new patients can be challenging, but there are resources to help. The Collège des médecins du Québec (CMQ) website often has a "Find a Doctor" tool or list. You can also use the Guichet d'accès à un médecin de famille (GAMF). Asking friends, family, or colleagues for recommendations is also helpful. Contacting local community health centres or clinics directly to inquire about their new patient policies is another strategy. It may take time and persistence to secure a family doctor.

Is seeing a family doctor (Médecin de famille) covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary visits to a family doctor are typically covered by the Régie de l'assurance maladie du Québec (RAMQ) for eligible residents with a valid provincial health card. However, some services, such as cosmetic procedures, most travel medicine consultations, sick notes for work/school, insurance forms, and driver's medicals, may not be covered and might have an associated fee. Please confirm with GMF Clinique médicale Saint-Laurent if you have questions about specific services or potential fees.

Does Dr Grenier at GMF Clinique médicale Saint-Laurent offer virtual (video) or phone appointments?

Yes, Dr Grenier at GMF Clinique médicale Saint-Laurent offers virtual (video) and/or phone appointments for certain types of consultations when clinically appropriate. These can be convenient for discussing some test results, managing stable chronic conditions, prescription renewals for ongoing medications (not controlled substances), or for certain mental health follow-ups. However, many conditions, new problems, or situations requiring a physical examination will still necessitate an in-person visit for accurate assessment and diagnosis. Please discuss with our reception staff or Dr Grenier if a virtual appointment might be suitable for your specific needs. Provincial health plan coverage for virtual visits may vary; please check with GMF Clinique médicale Saint-Laurent regarding any potential fees for uninsured virtual services.

What is 'continuity of care' and why is it important with a family doctor like Dr Grenier?

Continuity of care means having an ongoing relationship with your family doctor, Dr Grenier, and his team over time. It's important because it allows Dr Grenier to get to know you, your health history, your values, and your family context comprehensively. This deep understanding helps Dr Grenier make more informed diagnoses, tailor treatments to your specific needs, coordinate your care more effectively with specialists, and build a trusting therapeutic relationship. Studies show that good continuity of care with a family doctor is linked to better health outcomes, higher patient satisfaction, and more appropriate use of healthcare resources.

Do I need a referral to see a family doctor (Médecin de famille) in QC?

Generally, you do not need a referral to see a family doctor in Quebec if the doctor is accepting new patients. However, finding a family doctor who is accepting new patients can be challenging. Provincial resources, such as the CMQ website or the GAMF, may be helpful in your search. A referral from a family doctor is usually required to see medical specialists.

What does 'preventative care' involve with a family doctor like Dr Grenier?

With Dr Grenier, preventative care means taking proactive steps to maintain your health and prevent future illness. This encompasses services like scheduled immunizations, screenings for diseases you might be at risk for (based on age, family history, etc.), discussions about lifestyle modifications to reduce risks (e.g., related to nutrition, physical activity, substance use), and regular health assessments to monitor your overall status. Dr Grenier works with you to create a personalized prevention plan.
