    Michael Berger, MD (he, him, his)

    Academic Role: PGY-4

    Hello! I took a very circuitous route to both medicine and UMass. I was born and raised in New Jersey and then went to the University of Michigan where I studied Chemical Engineering. After a year with what I thought was my dream job working for a renewable fuel start-up in Colorado, I decided my life’s calling might be something else. I became a licensed EMT and worked as a ski patroller at Loveland Ski Area before beginning medical school at the University of Colorado. After some very early clinical experiences, I knew I wanted to be an Ob-Gyn. I matched and began residency at Hahnemann University Hospital. My life was upended when that hospital announced its sudden closure and my colleagues and I all had to scramble to find new homes. I am forever grateful that UMass “adopted” me. I cannot imagine having landed in a more welcoming or supportive program and I am thrilled to be learning the practice of medicine here.

    Academic Role: PGY-4

    I grew up in the suburbs of Boston. I went to Trinity College in Hartford, CT and then completed a post-baccalaureate program at Boston University. Afterwards, I worked in a neurology research lab at Brigham and Women’s Hospital. I then went to medical school at George Washington University, and now I’m back in the state where it all started. My wife and I love being back in Massachusetts! We like to spend free time with family, exploring new restaurants, and traveling. UMass is a great place to train. My colleagues are not only amazing physicians, but also fun to work with. The faculty are excellent teachers and passionate about their work. It has been an incredible experience so far, and I look forward for more to come!

    Academic Role: PGY-4

    Hello! I'm Caroline and I was born and raised in Georgia. I got a taste of life in New England when I attended college at Tufts University where I majored in Spanish and Community Health. I returned to Georgia for medical school at the Medical College of Georgia, but couldn't stay away for too long! I am passionate about women's health and advocacy and felt that UMass was a place that shared those passions. On my interview at UMass there was a sense of family and camaraderie amongst the residents and faculty that had already made me feel at home here. Since starting residency, this has continued to be true. The faculty, staff, nurses, and my wonderful co-residents are incredibly welcoming and supportive and I could not think of a better place to train. Outside of residency, I enjoy exploring new craft breweries, traveling, photography and eating large amounts of chocolate.

    Academic Role: PGY-4

    I was born and raised in Western Mass. I went to UMass Amherst for college and UMass for medical school, so you could call me a UMass lifer! I studied chemical engineering in college. I loved my time as a medical student at UMass, and found the community to be wonderful, supportive, and so much fun. Therefore, when the time came to decide where to go for my residency, UMass just felt like home. I absolutely love living in Worcester, with its amazing restaurants and fun places to explore. I am thankful to have the most wonderful co-residents and am so excited to have stayed here for residency! My hobbies include cuddling on the couch and watching HGTV with my Bassett Hound, Bruce, playing soccer, and woodworking/DIY projects.

    Academic Role: PGY-4

    I am originally from Maynard, MA but moved to Lancaster, PA for half of my childhood. I came back to MA for undergrad at Wellesley College and stayed on in Boston in a research job for three years after college. I returned to PA to go to medical school at Penn State where I was involved in the Global Health program and in Med Students for Choice. I am thrilled to be back in MA once again for residency at UMass! The program here is very supportive and we have opportunities to explore diverse interests. I love spending time with my coresidents, both in and out of the hospital. Worcester is a great place to live and I look forward to continuing my exploration over the coming years.

    Academic Role: PGY-4

    Hi, I’m Jordan. I grew up in Massachusetts and I first moved to Worcester to study Biology at the College of the Holy Cross (HC). My co-resident Michelle and I both joined Teach for America after graduation from HC. For three years, I taught middle and high school science at LCHS in Itta Bena, Mississippi (go Tigers!). From leading a novel study of Rebecca Skloot’s “The Immortal Life of Henrietta Lacks” to teaching the 7th grade reproductive health class, my passion for medicine always found a way into my classroom. I then went on to complete my medical training at Penn State University, with another co-resident, Elizabeth. We both participated in the Global Health Scholars Program, through which I studied women’s health in Ecuador.  I was so happy to return to Worcester to join of the UMass OB/GYN family!
