About Johan Nordenstam
I am a colorectal surgeon in the University of Florida Department of Surgery. My clinical interests surround treating anorectal physiology and the treatment of colorectal diseases such as colon cancer and rectal cancer. My expertise is in ulcerative colitis, Chron’s disease, colorectal cancer, hemorrhoids, colonoscopy, rectal prolapse and fecal incontinence.
I received my medical degree from the Karolinska Institute in Stockholm, Sweeden. I completed my residency in colon and rectal surgery at the University of Minnesota, where I remained to complete an accredited fellowship in colon and rectal surgery and minimally invasive colorectal surgery. During my residency and fellowships, I was a research fellow at the University of Minnesota Division of Colon and Rectal Surgery.
I earned multiple national awards and accolades over the years, including the Roy A. Taylor Distinguished Alumnus of the Year Award from the University of North Carolina Asheville in 2021 and an Award of Appreciation from the University of Illinois Chicago in 2017. I am a member of the American Society of Colon and Rectal Surgeons and the Society of American Gastrointestinal and Endoscopic Surgeons.
