Current Fellow

John Konen, MD

John Konen is the current Colon and Rectal Surgery Fellow at the University of Massachusetts. He grew up in Grosse Pointe, Michigan and completed his Bachelor of Science in Neuroscience at the University of Michigan, followed by his MD from Michigan State University. He then moved to Vermont to complete his general surgery residency at the University of Vermont Medical Center (UVMMC). During his surgical residency, he conducted research with Dr. Gary Mawe in the department of Neurological Sciences and was awarded the Young Investigator Award by the International Federation of Neurogastroenterology and Motility for his work on colonic motility and luminally acting 5-HT4 receptor agonists. He also conducted research on organ preservation in rectal cancer, and a funded prospective trial in carbohydrate loading enhanced recovery in colorectal surgery patients. He was the recipient of the 2021 Alpha Omega Alpha Honors Society Housestaff Award during his time at the University of Vermont. In his free time, John enjoys hiking, biking, camping, playing music, and spending time with his friends and family. John is a board-eligible general surgeon who is excited to continue his training at UMass to become a colon and rectal surgeon.
