Why did I choose to train at Barre? When looking for potential residencies during my fourth year of medical school, I was fortunate to get an opportunity to spend a month at the Barre clinic. I realized that Barre was exactly the type of residency I was looking for. In this program, I could get full-spectrum primary care experience working in a rural clinic with the added benefit of being part of a larger academic institution. Also, the residents and faculty showed the kind of care and compassion for their patients that I hope to be able to provide, and I knew I had a lot more to learn from them.

Hobbies: Hiking with my dog Rooster, a Corgi mix, and listening to history podcasts.
Fun Facts: I'm originally from Ukraine and moved to the United States before my ninth birthday, and I'm still fluent in Ukrainian.

West Virginia University School of Medicine
Graduate:  MPH in Occupational and Environmental Health at West Virginia University
West Virginia University

Hometown: Fairmont, West Virginia 
Family Medicine interests: Women's health, preventive medicine and outpatient care
Why did I choose to train at Barre?  My husband and I wanted to explore somewhere that wasn't West Virginia, considering we had lived there our whole lives. UMass Chan seemed like a great choice because it is close to some of our family in Boston and offers a culturally diverse patient population. I chose Barre specifically because it extends an exceptional combination of rural health training in the clinic setting along with the training and resources provided by a large university health system.
Hobbies: hiking and spending time outdoors, tennis, reading, checking out local breweries, doing pretty much anything with my husband and dog
Fun Facts: I couples matched with my husband Mason (Internal Medicine intern). Mason and I just got married this May in Italy and we have a very sweet 6 year old Newfoundland named Brownie.

Why did I choose to train at Barre? I chose to train at UMass because I wanted to train under supportive faculty at a large academic center with a diverse patient population.

Northeastern University

Hometown: Needham, MA
Family Medicine interests: Full-spectrum primary care, Palliative Care, Narrative Medicine, Osteopathic Manipulative Medicine, Medical Education
Why did I choose to train at Barre? I wanted to return home to New England for my training. UMass stood out to me because of the combination of rigorous academic training and full spectrum primary care that were integrated into the communities in Worcester and Barre. I also felt like the residents, faculty, and administrators were my kind of down-to-earth and genuine people that I would want to spend 3 challenging years training beside. I was particularly interested in Barre because of the chance to learn in both an urban-academic and rural environment and the opportunity to truly "own my patients."
Hobbies: Songwriting and music production, drumming, oil painting, creative writing, spending time with my wife Lucy and our dog Beep!
Fun Facts: I made the music for "Cube Runner," one of the first games released in the Apple app-store. It has been downloaded over 6 million times!

Nicholas Croce, DO

Undergraduate: UMass Lowell
Hometown: Amesbury, MA
Family Medicine Interests:  Osteopathic Manipulative Treatment, Rural Medicine, Obstetrics, Outpatient Procedures, Pediatrics, Teaching
Why Did I Choose to Train at Barre? My goal is to be a small-town, old-school, jack-of-all trades doctor; and the inherent rigors of training at Barre Family Health Center will best prepare me for this.  UMass Chan Family Medicine Residency is jam-packed with compassionate, talented, and humanistic people who will challenge me to be a loving, full-spectrum, patient-first provider.
Hobbies: Family time, Basketball, Fitness and Nutrition, Hiking, Woodworking, Home/Auto DIY, Boston Sports
Fun Facts: I am a husband, father, and self-proclaimed old soul who hopes to someday have a baseball team of children!  I come complete with a fully-loaded arsenal of dad-jokes and puns, funky socks, and a seemingly endless loop of year-round Christmas music playing in my head.  I pride myself on making creative, not-quite-Pinterest-worthy cakes for my wife, being the guy who brings homemade gifts to high-end functions, memorizing children’s books with my son, and eating the same breakfast nearly every day for eight years (and counting.)

Medical School: University of Connecticut School of Medicine
Undergraduate: University of Connecticut
Hometown:  Bethel, CT
Family Medicine interests: Rural practice, Integrative Medicine
Why did I choose to train at Barre? When I was looking for a program, I wanted to be able to train with a rigorous full scope rural family medicine program, but I also didn’t want to be far away from my family and friends, and for that Barre was a perfect fit for me. The program has a long history of excellence in training family medicine physicians, with smart and supportive faculty, and the balance of the academic setting and rural care made me believe this program would prepare me to be the best physician I can be.

  Alex Doering, MD, Chief Resident 

Medical School: Geisel School of Medicine at Dartmouth College
Undergraduate: Bowdoin College
Hometown: Windham, Maine
Family Medicine interests: I particularly like geriatrics, palliative care, and addiction psychiatry
Why did I choose to train at Barre? I worked at UMass for two years before medical school, and I love the area. Of the three clinics, Barre allowed me to continue working in a rural clinic setting while still getting more inpatient cultural diversity in Worcester

Undergraduate: Washington and Lee University
Hometown: Lexington, MA
Family Medicine interests: Procedures, inpatient and outpatient care delivery, military and veteran's healthcare.
Why did I choose to train at Barre? I drank the Barre Health Center koolaid during a third-year medical school clerkship rotation, and my FMIS sub-internship in fourth year only further solidified my desire to stay at UMass for residency. Interviewing around the nation and seeing how FM was practiced in different regions, I found Barre to be the best of all worlds with outpatient practice in a rural healthcare setting complete with home visits, as well as rounding on inpatient wards at a large academic university hospital center. In my eyes that was the epitome of what it meant to be a clinician and family physician.
Hobbies: Being a dog dad, gardening, DIY home improvement, and grilling meat. 
Fun Facts: I'm 32 years old! I'm a third generation physician following my father and grandfather, and my sister is also starting her residency at UMass in Pathology.

Hobbies:  Basketball, Golf, Gardening, Hiking, Video games
Fun Facts: I was a back to back county free throw shooting winner in high school, I can cook almost anything in a Crock Pot, I had a rhinoplasty (nose-job) stemming from an inside fastball incident, my family won a toilet at a minor league baseball game (Lowell Spinners)
