Can I book an appointment directly or do I absolutely need a referral?

A referral from your family physician or another medical specialist is required to see Dr. Lee.

What is involved in a Comprehensive Geriatric Assessment (CGA)?

A CGA is a detailed evaluation specifically designed for older adults. It goes beyond standard medical checks to assess multiple domains including: medical conditions, medication review (polypharmacy), functional status (ability to perform daily tasks), mobility and fall risk, cognitive health (memory and thinking), mood (screening for depression/anxiety), nutrition, and social support systems. Dr. Lee uses this holistic approach to develop a personalized care plan.
