Ashton Kelley, MSN, APRN, FNP-C
I was born and raised in a small town in Northeast Arkansas; however, my family and I have spent the last four years in central North Carolina. My husband and I relocated to Columbia in the Fall of 2021 for my husband’s career and we are loving being back closer to family and exploring all Missouri has to offer. We have 2 small children, Noah and Caroline, that keep us on our toes!
I attended Arkansas State University for both my Bachelors and Master’s degree and I have almost 10 years of nursing experience as both an RN and a NP. I absolutely LOVE being a nurse! In the past, I have worked in the cardiovascular intensive care unit as an RN and, for the last 4 years, as a Cardiology Nurse Practitioner. Although I have spent the better part of the last decade in Cardiology, I am excited to jump into the asthma and allergy field and care for patients with different challenges. It is my goal to treat every single patient as I would want myself or my family treated and I love working with patients to make them feel better! My hobbies include traveling, hiking, reading, and being with friends and family.
