From the Doctor

In 2017 my family moved here to Jacksonville from Dallas, Texas. My husband and our son enjoy going to the beach and staying active with my parents who live in nearby St. Augustine.

My approach to patient care is it to incorporate the whole family in the treatment plan. My ultimate goal in my preventive practice is to empower families to make heart healthy choices today which will lead long healthy lives in the future.
