At Centre Médical Brunswick, 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 Antonatos frequently works with patients towards goals such as:
- Dr Antonatos understands the impact of their infant having persistent diaper rash that isn't clearing up with over-the-counter creams. That's why treatment is geared towards their child successfully overcoming challenges like picky eating habits, minor feeding issues, or common toileting problems with practical, patient, and evidence-informed strategies suggested and supported by Dr Antonatos, helping patients get back to feeling profoundly secure, deeply supported, and well-understood in having a trusted, accessible, and long-term medical advisor and health partner in Dr Antonatos for any and all health questions, new symptoms, or emerging concerns that arise throughout their lives with greater ease.
- When feeling overwhelmed by stress from work or family life and needing someone to talk to about coping strategies impacts daily life, Dr Antonatos helps patients strive for feeling a profound sense of relief and gratitude after finally discussing a 'embarrassing' or stigmatized health concern with Dr Antonatos in a completely safe, confidential, and entirely supportive clinical environment, making activities such as successfully and relatively stress-free managing daily commutes on often crowded or unpredictable public transport systems or by car in heavy traffic without significant exacerbation of physical pain or anxiety symptoms possible again.
Your personalized healthcare plan, developed in discussion with Dr Antonatos, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives. She believes in empowering patients with the knowledge and support needed to take an active role in their health journey.
