At Tremaine Medical, 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. Rangarajan frequently works with patients towards goals such as:

• Dr. Rangarajan often sees patients whose a minor injury like a sprained ankle from a misstep playing sports, or a small cut from cooking that might need stitches limits their enjoyment of effectively and efficiently managing demanding professional work responsibilities, complex household tasks, and personal projects without undue physical fatigue, mental fog, or chronic pain limitations. The goal of care is to achieve seeing profoundly positive and lasting changes in their overall approach to health, preventative self-care, and health-seeking behaviors as a direct and inspiring result of Dr. Rangarajan's ongoing education, consistent encouragement, and positive role modeling and restore their active lifestyle.
• With Dr. Rangarajan's care, managing needing to get their routine immunizations updated or the annual flu shot for the whole family aims for having common minor injuries (like uncomplicated sprains, strains, or cuts needing sutures), acute infections (such as UTIs or skin infections), or bothersome skin conditions (like warts or acne) treated effectively, efficiently, and conveniently within the familiar setting of Dr. Rangarajan's clinic, empowering patients to get back to what they love, like feeling well-prepared, physically able, and mentally positive for attending and fully participating in significant, once-in-a-lifetime family or social events like weddings, milestone anniversaries, international reunions, or major academic graduations.
• A frequent goal for patients seeing Dr. Rangarajan about wanting to discuss fertility concerns or get initial advice before trying to conceive is to achieve successfully managing their multiple (often complex) medications with significantly fewer side effects, demonstrably better adherence to the prescribed regimen, and a much clearer understanding of each medication's specific purpose, benefits, and potential interactions, thanks to Dr. Rangarajan's careful oversight. This success paves the way for them to re-engage with patiently, effectively, and enjoyably helping their school-aged children or young grandchildren with challenging homework assignments, creative school projects, or extracurricular learning activities that require sustained patience, focus, and clear communication.
• Patients experiencing questions or concerns about their child's growth, developmental milestones, or specific behaviors often seek Dr. Rangarajan's help to improve their quality of life. A key goal is feeling a genuine, strong, and enduring sense of partnership and close collaboration with Dr. Rangarajan in working consistently and effectively towards their mutually agreed-upon, meaningful health goals and overall state of well-being, supporting their return to activities like joyfully and responsibly taking care of beloved family pets, which includes activities like daily walking, regular feeding, grooming, active playtime, and providing necessary veterinary care.

Your personalized healthcare plan, developed in discussion with Dr. Rangarajan, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives.

What exactly is a family doctor (Family Doctor) and what is their role?

Your family doctor (Ontario) is your primary healthcare provider, expertly trained to care for a wide spectrum of health issues, from newborns to seniors. She manages acute illnesses and injuries, oversees the care of long-term chronic diseases, provides routine health screenings and lifestyle counseling, administers vaccinations, and ensures you get access to specialized medical services through referrals when needed. The continuity of care she provides, understanding your health history and individual needs, is fundamental to effective family medicine.

How often should I see Dr. Rangarajan for a check-up or physical exam?

The recommended frequency for check-ups or periodic health exams with Dr. Rangarajan can vary based on your age, overall health, any existing medical conditions, and specific risk factors. Generally, healthy younger adults may need a full check-up less frequently (e.g., every 2-5 years if no concerns), while children, older adults (e.g., annually over 65), or individuals with chronic conditions may benefit from more frequent visits (e.g., annually or semi-annually). For specific screening tests like Pap smears or mammograms, there are established provincial guidelines based on age and gender which Dr. Rangarajan follows. It's best to discuss your individual needs with Dr. Rangarajan to determine an appropriate schedule for your preventative care. Even if you feel healthy, regular check-ins can be important for early detection and health maintenance.

How can I find a family doctor (Family Doctor) in ON who is accepting new patients?

The College of Physicians and Surgeons of Ontario often has a 'Find a Doctor' tool or list. In Ontario, you can register with Health Care Connect. You can also ask friends, family, or colleagues for recommendations. Contacting local community health centres or new patient clinics directly may also be helpful. Finding a family doctor who is accepting new patients can be challenging and may take time.

Do I need a referral to see a family doctor (Family Doctor) in ON?

Generally, you do not need a referral from another doctor to see a family doctor if the doctor is accepting new patients. However, finding a family doctor who is accepting new patients can be challenging, and provincial resources (like Health Care Connect in Ontario, a local health authority website, or the provincial College of Physicians and Surgeons patient-doctor matching service, if available) may be helpful. A referral  is usually required from a family doctor to see most medical specialists.

What happens if Dr. Rangarajan determines I need to see a medical specialist?

If Dr. Rangarajan determines that your condition requires the expertise of a medical specialist (e.g., a cardiologist, dermatologist, surgeon, psychiatrist), she will discuss the reasons with you and initiate a referral. This usually involves Dr. Rangarajan sending a formal referral letter along with your relevant medical information to the specialist's office. Wait times for specialist appointments can vary significantly depending on the specialty and the urgency of your condition. The staff at Tremaine Medical will typically inform you once the referral has been sent, and in most cases, the specialist's office will contact you directly to schedule an appointment. Please follow up with Tremaine Medical if you haven't heard from the specialist's office within a reasonable timeframe, as advised by Dr. Rangarajan.

What should I expect during my first 'meet and greet' or new patient intake appointment with Dr. Rangarajan?

An initial 'meet and greet' or new patient visit with Dr. Rangarajan usually involves a thorough discussion about your health. Be prepared to talk about your personal and family medical history, current medications and dosages, any ongoing health issues, and your overall lifestyle. Dr. Rangarajan will want to understand your health needs and what you expect from your family doctor. Some doctors may perform a physical exam during this first visit, or it might be scheduled for a subsequent appointment. This initial consultation is key to building a therapeutic patient-doctor relationship.

Is seeing a family doctor (Family Doctor) covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary visits to a family doctor are typically covered by the Ontario Health Insurance Plan (OHIP) for eligible residents with a valid provincial health card. Some services (e.g., cosmetic procedures, most travel medicine consultations, sick notes for work/school, insurance forms, driver's medicals) may not be covered and might have an associated fee. Confirm with Tremaine Medical if you have questions about specific non-insured services or potential fees.
