Class of 2024

	Gassan Kassim, M.D.  Internal Medicine Residency location: Icahn School of Medicine at Mount Sinai, New York, New York "My GI fellowship at Mayo Clinic has been an amazing experience so far. As I was going through my interview season, it became obvious to me that here at Mayo, everyone takes a genuine and personal interest in your education, your well-being, your academic endeavors, and your career. The program is built on the foundation of mutual respect and is focused on meeting the individual and unique needs of every fellow. Furthermore, this program has been able to create the perfect environment that allows fellows to let their guards down, feel comfortable, and, in turn, focus on patient care and, in parallel, master their clinical and endoscopic skills. Furthermore, the program offers mentorship in every sub-discipline in GI, and all the faculty are just a friendly conversation away. Completing a fellowship here will provide you with a unique set of skills and with lifelong relationships that will help you become the best GI physician you can be."
	Kevork Khadarian, M.D. Internal Medicine Residency location:  Los Angeles General Medical Center and University of Southern California, Los Angeles, California "I chose to pursue gastroenterology and hepatology training at Mayo Clinic given the program's commitment to providing excellent patient care by incorporating the latest research and state-of-the-art technologies. This is evident across any subdivision within the department, which is led by renowned faculty who also provide invaluable mentorship every step of the way. Additionally, living in Phoenix, Arizona, provides innumerable opportunities to explore the beautiful outdoors year-round when out of the office, which was very important to me."
	Anna Silverman, M.D. Internal Medicine Residency location: University of California San Diego  "I chose Mayo Clinic because of its commitment to the three shields of medicine—teaching, research, and patient care. I knew I was interested in IBD; however, I was looking for a phenomenal foundational education in the entire breadth of GI. I was immediately impressed by the strength of the faculty in every subspecialty within GI. My experience at Mayo Clinic has been unparalleled and I love the environment we are able to learn and grow in here. The cherry on top is living in such a phenomenal city where life outside of work is just as wonderful as life at the hospital."

Class of 2025

	Margaret Liu, M.D. Internal Medicine Residency location: Dartmouth-Hitchcock Medical Center, Lebanon, New Hampshire "I chose Mayo Clinic for my fellowship because of the stellar patient-centered clinical training, breadth of GI pathology, innumerable research opportunities and areas of collaboration with experts within every subspecialty of GI, opportunities for early career building, and the amazing and supportive gastroenterology and hepatology team I get to work with every day."
	Sean Sileno, M.D. Internal Medicine Residency location: Mayo Clinic in Jacksonville, Florida "I chose Mayo Clinic for many reasons. For me, it started with the people. Prior to the application process, I was urged to apply here due to the reputation of the program, the success of previous residents from my residency program that had matched there, and its faculty. Once I got to my interview, I felt that the program was extraordinarily supportive and the goals for the fellows were in line with my personal goals. At my interviews, the faculty and chief fellows all made me feel comfortable and it was obvious that the program had a great culture that I felt that I would fit in with."
	Jaclyn Tuck, M.B., B.Ch., M.A. Internal Medicine Residency location: Mayo Clinic in Phoenix, Arizona "I completed my residency here at Mayo Clinic, and from my first rotation with the GI division, I knew I wanted to stay here for fellowship. Between the collegiality among the fellows and staff, mentorship from world-class attendings, and exposure to a wide array of pathology, I knew Mayo Clinic would equip me with the skills I need to flourish in the field of gastroenterology. I feel so honored to train here and be part of the GI family. In addition, the vast expansion of Phoenix and its surrounding cities, has added to an already social and adventurous place to live."
