MD., F.A.A.P.

She worked as an assistant social worker in NYC and as a research assistant for a program on primary care systems and education before entering Harvard Medical School. She completed her training at Massachusetts General Hospital for Children because it had the breadth of patient complexity of a larger hospital with individualized attention & flexibility of a smaller program that allowed her to focus on primary care. She is very excited about the opportunity that pediatricians have to support families in building healthy routines and habits that will launch children into a healthy adulthood.  Dr. Brubaker & her husband used to enjoy traveling and are now becoming more acquainted with New England!  In her free time, she enjoys reading, hiking and trying to train her stubborn puppy Willow.
