Alison Graf, NP, is a board-certified nurse practitioner with a strong passion for preventive and patient-centered care. She earned her Bachelor of Science in Nursing through Kennesaw State University’s accelerated program in 2019 after first completing her undergraduate studies in biology with a minor in psychology.

Her nursing journey began after the birth of her first child in 2018, when the compassionate care she received from nurses inspired her to pursue the profession herself.

Those experiences fueled her commitment to helping people prevent illness and address the root causes of their symptoms.

In 2023, Alison completed her Master of Science in Nursing at Kennesaw State University and became board-certified by the American Association of Nurse Practitioners. She believes every patient deserves to be heard and supported by a healthcare provider who is fully invested in their well-being.
