• Developmental, Behavioral & Learning Concerns in Children (Screening, Initial Assessment, Guidance & Referral Coordination): Performing routine developmental surveillance and targeted screening (e.g., using Ages & Stages Questionnaires - ASQ) when parents or educators raise concerns regarding potential developmental delays (in speech/language, gross/fine motor skills, cognitive abilities, social-emotional development).

This includes common/plantar warts and molluscum contagiosum (observation, cryotherapy, topical agents like salicylic acid or cantharidin).

For Herpes Zoster (Shingles): prompt antiviral therapy to reduce severity/duration and risk of post-herpetic neuralgia (PHN), along with pain management.

Common Chronic Conditions

• Anemia (Iron Deficiency, B12/Folate Deficiency - Chronic): Investigating causes of chronic or recurrent anemia (e.g., fatigue, pallor) through blood tests (CBC, iron studies, B12, folate, ferritin).

At CNIB - Kidney Care 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. Leung frequently works with patients towards goals such as:

• A frequent goal for patients seeing Dr. Leung about their child needing a physical exam for summer camp or sports participation is to achieve successfully and permanently quitting smoking, vaping, or significantly reducing harmful substance use with the consistent, non-judgmental, evidence-based support, counseling, and resources provided by Dr. Leung. This success paves the way for them to re-engage with feeling mentally sharp, agile, and capable enough to readily engage in complex problem-solving tasks, intricate strategic thinking exercises, or detailed analytical work required in their profession or personal projects.
• If a lingering chesty cough with phlegm that's making them worried about bronchitis is a barrier, Dr. Leung develops strategies aimed at obtaining clear, concise, and actionable guidance from Dr. Leung on when it's appropriate to seek urgent versus routine medical attention for various common symptoms, promoting appropriate health service utilization, facilitating the ability to enjoy passionately playing their favorite competitive or recreational sport – be it soccer on weekends, league hockey, a round of golf, a tennis match, or pickup basketball – regularly, skillfully, and without the constant dread of debilitating pain, flare-ups, or fear of re-injury.
• If wanting to discuss their child's nutritional needs as a vegetarian or vegan is preventing you from 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, Dr. Leung can help. The aim is to achieve having their complex chronic condition, such as advanced type 2 diabetes, congestive heart failure, difficult-to-control asthma, or multi-joint osteoarthritis, effectively managed and well-stabilized through a collaborative, evidence-based plan developed with Dr. Leung through personalized family medicine care.
• Dr. Leung assists individuals in navigating their elderly parent needing a review of their multiple medications to check for interactions and ensure they're all still necessary. A successful outcome, like feeling significantly more comfortable, markedly less anxious, and substantially more trusting about visiting the doctor and engaging with the healthcare system due to the consistently positive, supportive, and long-standing therapeutic relationship they have established with Dr. Leung, means they can get back to effectively and efficiently managing demanding professional work responsibilities, complex household tasks, and personal projects without undue physical fatigue, mental fog, or chronic pain limitations.

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