Ashley Rambo, MSN, RN, BC-AGACNP, CCRN

Nurse Practitioner

From a young age, I was driven by a desire to help and care for others. My fascination with all things scientific fueled my curiosity about how the world works. A pivotal influence in my early years was my best friend’s father, a physician, who introduced me to the world of medicine.

Despite financial challenges, I pursued my education and became a Registered Nurse. My journey didn’t stop there; I continued my studies and achieved certification as an Acute Care Adult Gerontology Nurse Practitioner. Over the past decade, I have worked as a nurse practitioner in a hospital setting, gaining invaluable experience. However, I soon realized that my true passion lay not just in treating patients, but in preventing hospitalizations.

This year, I was thrilled to join Dr. Boster’s team, where I can contribute to proactive and preventative care. Having collaborated with Dr. Boster previously, I am well aware of his dedication to his patients. The Boster Center for Multiple Sclerosis embodies the kind of patient-centered, preventative work that I am passionate about, and I am excited to be part of such an esteemed group.

I have always know I wanted to be involved in the medical field. Early in my career I worked in the Emergency room and as a Paramedic. I moved into the ICU and spent several years working in the Columbus area as both a bedside nurse and staff educator. After finishing my Masters degree I completed a fellowship in Urgent Care Medicine.

My mom was diagnosed with progressive MS in the early 2000’s. Watching both her challenges and strength while navigating this disease has provided me with a unique view into the effects of this disease. I am excited to be a part of the once going research and care of individuals like her.
