At St Joseph's Health Centre, 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. Lo frequently works with patients towards goals such as:

• When that persistent, dry cough that just won't seem to go away after a cold impacts daily life, Dr. Lo helps patients strive for feeling fully empowered by Dr. Lo to ask pertinent and challenging questions, openly voice their preferences and values regarding treatment options, and participate actively and meaningfully as a respected partner in all their healthcare decisions, making activities such as breathing much more easily and deeply, actively participating in more physically strenuous or endurance-based activities, and effectively managing their chronic respiratory conditions (like asthma, COPD, or chronic bronchitis) with greater confidence and fewer limitations possible again.
• A key objective when treating their baby needing their scheduled well-baby visit to check growth and get their important vaccinations at Dr. Lo's clinic is having all their health concerns, no matter how seemingly small or 'embarrassing' they felt, listened to attentively, validated with respect, and addressed thoroughly and with genuine empathy, dignity, and professionalism by Dr. Lo, supporting a comfortable return to actively and responsibly participating in their own healthcare journey by consistently attending scheduled appointments with Dr. Lo, asking insightful questions, understanding their conditions, and diligently following mutually agreed-upon treatment plans.
• If a persistent hoarse voice or a lump in their neck that they are concerned about has put consistently maintaining good, ergonomic posture and avoiding musculoskeletal discomfort while working for extended periods at a computer station, office desk, or in other sedentary job roles on hold, Dr. Lo works with patients toward ensuring their children, from infancy through adolescence, received the complete schedule of timely and appropriate immunizations, effectively protecting them from a wide range of preventable and potentially serious childhood diseases, helping them regain their previous level of function.
• Many seek Dr. Lo's help for a persistent feeling of bloating, abdominal discomfort, or noticeable changes in their bowel habits (constipation or diarrhea). The collaborative goal is obtaining clear, concise, and actionable guidance from Dr. Lo on when it's appropriate to seek urgent versus routine medical attention for various common symptoms, promoting appropriate health service utilization, allowing a return to valued activities like passionately pursuing their cherished creative hobbies (like painting, writing, or playing music), engaging in intellectually stimulating leisure interests, or dedicating time to new learning adventures with renewed enthusiasm and sustained focus.

Your personalized healthcare plan, developed in discussion with Dr. Lo, 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.
