Our Fellows

First Year

Jeremy Chimene-Weiss, MD

I grew up in Cambridge, Massachusetts and spent my undergraduate years at Bowdoin College in Brunswick, Maine. I returned to the Boston-area to work as a research assistant at Joslin Diabetes Center, before starting medical school at Boston University, where I remained for internal medicine residency. I am very excited to be at Dartmouth Hitchcock Medical Center for GI fellowship, where I’m exploring another part of New England while training alongside a talented group of clinicians and educators. Within GI, I have particular interests in hepatology and medical education, but the list keeps growing. Outside of medicine, I love playing soccer, seeking out the best ice cream shops, watching Jeopardy, and traveling around New England with my fiancée and our dog, Pepita (who also loves the upper valley and all it has to offer).

Joshua Kirschenbaum, MD

I’m originally from Mountain Lakes, New Jersey, a small suburb about an hour west of New York City. Between college at Brown, medical school at NYU, and IM residency at Tufts, I have spent my time since high school bouncing back and forth between New England and the Tristate area. I felt extremely lucky to match at Dartmouth where the sense of camaraderie among the GI faculty and their passion for teaching was extremely tangible even from afar on my virtual interview day. Within GI, the research I have worked on has focused primarily on demographic trends in and quantification of adherence to colorectal cancer screening recommendations, and I see myself most likely being interested in general GI or IBD at the end of fellowship. Outside the hospital you can usually find me on the nearest tennis court, at a local bar trivia night, or at home driving my wife nuts practicing the saxophone or ukulele at an unreasonably late hour.

Second Year

Robert Hashimoto, MD

I grew up near Seattle, Washington and spent my early years hiking around the Pacific Northwest. I attended the University of Washington for undergrad and was thrilled to subsequently join the team at Micron Technology in Boise, Idaho as a photolithography engineer in Research and Development and later as a Lead Engineer. Incentivized by scholarships and family ties, I moved across the country to San Antonio for medical school and pursued residency at Baylor in Houston, Texas. I then interviewed across the country for GI fellowship expecting to return to one of my alma maters in Texas or Seattle but immediately grew enchanted by the congeniality of the attendings and fellows at Dartmouth Hitchcock Medical Center. We made a leap of faith and moved Dartmouth Hitchcock Medical Center to #1 on the rank list and we have never looked back; our faith has been rewarded in every way.

Katherine Webber, MD

I was raised in Newton, Massachusetts and spent many weekends coming up to our family’s ski house at Okemo Mountain, where I learned how to ski and snowboard. I then spent 8 years in New Orleans, where I completed both undergraduate and medical school at Tulane University, spending my free time immersed in jazz music, crawfish and Mardi Gras parades. I’ve slowly made my way back up north, starting with Vanderbilt for internal medicine residency and now Dartmouth for fellowship! I’m thrilled to be part of this amazing group of GI providers and am particularly interested in immune mediated GI disease such as IBD, celiac, EoE, autoimmune hepatitis and PSC. Outside of work, I spend most of my time with my husband, newborn baby, and pet corgi. I enjoy playing tennis, hiking, snowboarding, going to the beach on cape cod and Broadway musicals!

Third Year

Megan Hennessey, MD

I grew up in Chelmsford Massachusetts and have spent most my life in New England, aside from the 4 years I lived in DC when I was in medical school at George Washington University. I completed my internal medicine residency at Dartmouth and was won over by the collegial atmosphere at the hospital and the natural beauty of the upper valley, and was thrilled to be able to stay for GI fellowship. I’m planning on pursuing general GI with areas of interest in immune mediated conditions and medical education. Outside of the hospital I enjoy growing flowers and vegetables in our garden, cooking, skiing with my husband, hitting the local trails, and exploring the upper valley to find the best secret swimming spots.

Jamie Horrigan, MD

I grew up in Hopkinton, Massachusetts where the Boston Marathon starts. I then moved to New York as part of the Siena College/Albany Medical College early assurance medical program which focused on service, the humanities, and ethics to create more compassionate physicians. During my fourth year of medical school, I did an away rotation at Dartmouth Hitchcock Medical Center in GI and absolutely loved the people, the area, and the beautiful hospital. It was an easy decision to rank Dartmouth Hitchcock Medical Center #1 for residency. I then stayed on for a chief year and was thrilled to match into GI fellowship here. Within GI, my interests are in inflammatory bowel disease (IBD). Outside of medicine, I enjoy anything water related in the summer, especially waterskiing and paddle boarding, downhill skiing in the winter, trying new recipes, and going for long walks. My husband and I live in Lebanon with our 2 cats, Leo and Luna.
