About
Who We Are
Horizons Healthcare has been in business since 2006. Our goal is to provide comprehensive care in our Snellville office or the patient’s own living environment. Our nurse practitioners manage acute and chronic medical conditions through comprehensive history taking, physical exams, and the ordering of diagnostic tests and medical treatments. Our nurse practitioners also specialize in geriatric psychiatry, assessing and treating mood disorders, confusion, and behavioral disturbances that often accompany dementia.
What Is a Nurse Practitioner?
A nurse practitioner (NP) is a registered nurse (RN) who has completed advanced coursework and clinical education (a minimum of a master’s degree) in the diagnosis and management of medical conditions, including chronic illnesses. The core philosophy of the NP field is individualized care. Nurse Practitioners focus on patients’ conditions as well as the effects of illness on the lives of the patients and their families. If prescriptions are needed, NPs in the state of Georgia are able to prescribe and manage medications.
Patricia Gray-Smith
APRN BC FNP/ANP
Owner- Horizons Healthcare
Nurse Practitioner Patricia Gray-Smith has over thirty years of nursing experience. She received her Master’s degree in Nursing and her Post Master’s Certificate in Family Health from Stony Brook University of New York. Patricia is certified by AANP (American Academy of Nurse Practitioners). During her time working as a Hospitalist at Beth Israel Hospital in New York, Patricia became aware of the gap in transitional and on-going care when the patients were discharged back home. With that need in mind, Horizons Healthcare was established in 2006. Patricia provides both primary care and geriatric psychiatry to her patients and is committed to caring for the most vulnerable populations. Her passion lies with older adults, especially those with dementia. And as such, her goal is to provide healthcare in the patient’s own familiar setting. Today she serves patients both in our Snellville office and in the community where her patients reside.
