Why Geriatrics? Geriatrics focuses on the whole person and meets each patient where they are which is how all medicine should be practiced.

Bio

Why geriatrics?: I love the diversity of geriatrics, and how chronological age often tells you so little about a person's functional status and reality.

And I love learning from the lived-experiences, wisdom, and resilience of my older adult patients.
