Executive Board

President


Michael Koo

Hi everyone, my name is Michael Koo, and I’m proud to serve as your student body president this year. I’m an MD-MBA student in my final year of the program, applying for anesthesiology in the 2025 match. I was born in Seoul, South Korea, and moved to Maryland near Baltimore when I was 4, spending the next 20 years of my life there before coming to Dartmouth for medical school. I majored in Biomedical Engineering and Applied Math/Statistics with a minor in Africana Studies at Johns Hopkins University, graduating in 2018. At Geisel, I served as the former treasurer for two years, as a peer tutor, and at the community vaccine clinic. I have a passion for improving healthcare systems and access, having worked at Operator (formerly Atana) during my gap years to help automate patient billing negotiations, and at Welbe Health this summer to help launch PACE centers, a value-based care program that assists high-risk seniors in society. I love cooking and worked at Ekiben in Baltimore, the best restaurant in the world. Catch me outside of school playing pickup basketball.

 

Vice President


Michelle Dong

Hi everyone, I’m Michelle! I grew up outside of Toronto, Canada, and graduated from Western University in 2018. Before coming to Geisel, I earned my master’s in immunology from Harvard and worked as a clinical research coordinator in Boston. I previously served on student government as Chair of Wellness for 2 years, and it's an honor and a privilege to take on this new role as Vice President! When I'm not in the hospital, you'll find me watching Love Island with my roommates, going to concerts, tending to my houseplants, convincing my friends to come to Barry’s Bootcamp classes with me, and tackling my ever-growing list of to-be-read books on Goodreads. I look forward to connecting with everyone during my 4th and final year in student government and continuing our great work in making Geisel a great place to learn and grow!

Co-Chairs of Professional Development


Derek Colaizzo

Hello everyone! My name is Derek Colaizzo and I was born, raised and am very proud to be from New Jersey! I graduated from Princeton University in 2017 with a degree in History of Science, where I did my senior thesis on the history of chili pepper in western medicine. During undergrad, I walked on the varsity swim team, played saxophone in the music program, and was involved in the Big Sibs program. I decided to think about going into medicine following a shadowing program in Portugal I did prior to my senior year. Following graduation, I recorded an EP with my band, interned at a clinical research testing site, and was a beach lifeguard and bartender. Then I applied to a post bacc program at Columbia, which I completed last year. During the past year, I worked on a spinal surgery research team at the Hospital for Special Surgery and on a Chronic Kidney Disease study at the University of Pennsylvania. My interests in medicine are in orthopedics, pain management, health policy, and medical education. For hobbies, I love to play/listen to music (I play sax and guitar), cook, surf and watch sports. I am really excited to get involved with student groups and explore the surrounding nature. Looking forward to meeting you all.


Ian Lichtenstein

Hi y’all, my name is Ian Lichtenstein, and I am currently in my fourth year at Geisel. I grew up in the seacoast area of New Hampshire, went on to the University of New Hampshire, and then took a few years to do some research before coming to school in the Upper Valley. Since being at Geisel, I’ve loved being able to tutor and take part in initiatives to help others achieve their educational, professional, and career goals via the near peer shadowing program, the peer advising program, and the Big Sib Little Sib programs. I’m thrilled to serve as the Co-Chair of Professional Development with Derek to help grow these programs and develop new ways to help my colleagues reach their goals. Outside of Geisel, I love getting outside, exploring diners and odd places around the upper valley, and talking about how awesome the Norwich Inn is!
