Darci Blanchard
Program Coordinator

I live on top of a mountain in beautiful Vermont with my husband and three children. We designed and built our house four years ago, and continue to work on it today! Except for leaving for college, I have been in Vermont/New Hampshire for my whole life. Outside of work I enjoy camping, trips to the beach, photography, interior decorating, reading a good book, and seasonal favorites such as apple picking.

Jesse Davis
Program Coordinator

I grew up in New Hampshire and Vermont and, with the exception of college, have lived in Vermont since 1994. I’m blessed to call the Upper Valley home and enjoy the numerous opportunities for recreation, the arts and close knit communities that make up who we are. 

I enjoy supporting our Internal Medicine residents and helping them take on the challenges and opportunities of their residency at DHMC as they advance in the next chapters of their careers. I’m excited to see them grow as professional providers and in relationships that are formed through this extraordinary experience. 

When I’m not supporting our residents and staff, I am taking my dog for walks along the White River, diving into my love of aviation and space history, going to baseball games, gardening with my wife in the summer or being cozy near the wood stove in the winter.

Brianna "Bri" Eastman
Program Coordinator

I grew up in New York but moved to New Hampshire in high school and have lived all around the state since, from the Seacoast to Central NH to the White Mountains. I currently live up north in the White Mountains with my husband, our three-year old son and our two dogs.  We are in the process of closing on our dream home in Merrimack County which has beautiful views of Ragged Mountain. When I’m not working, you can usually find me riding my horse, relaxing with my husband and son, or exploring my love for all things aviation; which luckily enough, my son and husband also have!
