Alison Gilliland

The nursing dream started for me as a young child, as I always wanted to help people. I started working as a nurse’s aide in 1997 at Dartmouth Hitchcock Medical Center where I worked for just shy of 25 years. I completed my LPN in 2007 at River Valley Community College and joined the IV team at Dartmouth Hitchcock for 15 years. I completed my RN at Vermont Technical College in 2017, Bachelor’s degree in 2020 and Master’s Degree in Education in 2023 both at Franklin Pierce University. I started at Mountain Ridge in November of 2021, in hopes to expand my career in the Nursing education role. In April of 2024, I became the Director of Nursing.

Besides being educationally focused, I have been married for 34 years. I have three young adult children. When not working, I can be found outside enjoying the warm weather, tending to the numerous farm duties, helping my daughters with their horses, and my son with his tinkering on engines.
