    • Dr. Tierney is a diplomate of the American Board of Internal Medicine. The first in her family to pursue medicine, Dr. Tierney graduated from William Carey University College of Osteopathic Medicine in Hattiesburg, Mississippi in 2018. She completed her residency at the University of Mississippi Internal Medicine program in Jackson, Mississippi in 2021. She has both inpatient and outpatient experience. She is very passionate about outpatient medicine, which allows her to truly connect with patients and their families to discuss and achieve mutual healthcare goals. She is a strong advocate for evidenced based medicine. She has 5 years’ experience and her strengths include managing geriatric and medically complex patients such as those with COPD, heart failure, asthma, hypertension, and diabetes as well as conducting annual exams and transitional care management visits.

      Outside of medicine, her favorite football team is the University of Georgia Bulldogs (her undergraduate alum) and her favorite TV show is The Great British Bake-Off (she bakes a decent macron).
