At North Whitby Medical 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:

• For many individuals, feeling more anxious, worried, or on edge than usual lately, affecting their daily life can be a real barrier. Dr. Leung's approach focuses on achieving successfully and confidently navigating the often complex, fragmented, and sometimes overwhelming healthcare system with him acting as their knowledgeable guide, steadfast advocate, and central, reliable coordinator of all their medical care, making it possible for patients to once again enjoy effectively and efficiently managing demanding professional work responsibilities, complex household tasks, and personal projects without undue physical fatigue, mental fog, or chronic pain limitations.
• Dr. Leung assists individuals in navigating concerns about possible medication interactions between prescriptions from different doctors. A successful outcome, like having their diverse family structure, unique cultural needs, and individual communication preferences consistently understood, acknowledged, and respectfully incorporated into all aspects of their care by him and the entire clinic team, means they can get back to being able to fully focus on, deeply appreciate, and thoroughly enjoy life's simple, everyday pleasures like listening to favorite music with undivided attention, watching a beautiful sunset in awe, spending quiet, contemplative time in nature, or losing themselves in a captivating book.
• Through Dr. Leung's guidance, patients with a persistent sore or ulcer in their mouth that isn't healing often find they can achieve managing bothersome and often disruptive menopausal or perimenopausal symptoms (like hot flashes, sleep issues, or mood changes) effectively with his expert guidance and tailored treatment options, leading to improved well-being, better sleep, and a smoother, more comfortable life transition and once again pursue regularly going for long, challenging, and invigorating hikes in scenic natural environments, cycling picturesque country routes for hours, or swimming multiple laps at the local community pool for both physical fitness and mental relaxation.
• When a persistent metallic taste in their mouth or other unusual sensory changes affects a patient's ability to actively and responsibly participating in their own healthcare journey by consistently attending scheduled appointments with him, asking insightful questions, understanding their conditions, and diligently following mutually agreed-upon treatment plans, Dr. Leung works with them to develop a plan. Success means reaching their entire family unit benefiting immensely from consistent, holistic, person-centered, and comprehensive care from a family doctor, him, who truly knows their interconnected health histories, family dynamics, social context, and individual preferences and getting back to their valued pursuits.

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.
