About UMass: After finishing residency in Boston, I was looking for a clinic where I could provide quality, full spectrum care, including maternity care and osteopathic treatment, for families. Barre Family Health Center has a long history of dedication to the surrounding communities while also having the benefit of being a part of the UMass system allowing patients access to continuity and specialty care. I also very much enjoy clinical teaching and sharing the knowledge I have learned with the next generation of physicians. I feel very grateful for the opportunity to become a part of the Barre team and work with such a caring group of staff and providers.
Personal Facts: My training has taken me from coast to coast, from Boston to Colorado back to Boston and finally home to central Mass. I could not be more excited to return and provide care to the communities I grew up close to! Outside of work, I spend most time with family and friends. I enjoy the outdoors and am always trying to fit in as much skiing, paddleboarding, and hiking as possible!

About UMass: Our health centers are the strength of our program. Located in the community rather than in the hospital, our residents enjoy an opportunity to be a genuine community family physician while experiencing the excellent training offered in a major university medical center. 
About Choosing Family Medicine: I grew up with a general practitioner providing care to my family and was impressed with the way in which he was able to make it all seem like it would turn out all right. Meeting a community need as he did became my ambition and I felt I could only do that in Family Medicine. While the science of medicine is interesting, the relationship with patients is what I enjoy.

About UMass:  As a UMass Chan “lifer” (I did my undergrad, medical school, and residency all within the UMass Chan system), I have come to appreciate all that UMass Chan has to offer. The residency program is the perfect blend of high-quality training with amazing support for the residents. There is so much opportunity for learning and growth; when the time came to look for a full-time position, I realized that UMass Chan was the best place to pursue my goals of being an academic full-spectrum family doctor in Massachusetts.

About UMass: BFHC in my mind defines family medicine as you take care of people from birth to death, as well as provide urgent care, and OB care. You can't get more complete than that. It’s a wonderful place to work. It can get pretty busy, but it never loses its small town charm.
Personal Facts: I enjoy cutting people’s hair, and cooking, but not at the same time! (That would be a fire hazard.)

About UMass: I think UMass Chan offers extraordinary quality in academic, clinical, and research efforts – all with primary care as a core value.
