Dr. Helen Vasquez, MD

Geriatric Medicine Physician

Dr. Helen Vasquez has practised geriatric medicine for more than twenty years. Her appointments are longer than most, because the questions that matter to an older patient — what the eleven medications on the list are actually doing, whether the stairs are still safe, what the family is worried about — are not questions with quick answers. She works closely with caregivers, and treats them as part of the consultation rather than as an audience to it.
