Debra is a passionate nurse practitioner who has been with Catherine’s Health Center for over 19 years now. Debra is drawn to caring for underserved individuals and families with consideration of the community social determinants of health. Debra’s model of care always follows getting to know the patient first, as if you don’t know the patient’s life, you can’t always know if a treatment plan will work for them. In addition to caring for underserved individuals and families, Debra also holds interests in women’s health and care of immigrants, as her father was an immigrant.
