Dr. Seth Felder is a board-certified colon and rectal surgical oncologist in the Department of Gastrointestinal Oncology at Moffitt Cancer Center and treats diseases of the small intestine, colon, rectum, and anus. He is an Assistant Professor of Surgery and Assistant Professor of Oncologic Sciences at the University of South Florida Morsani College of Medicine. Following his colon and rectal surgery training at the University of Minnesota with international leaders within the field, he pursued additional training at Memorial Sloan Kettering Cancer Center in Advanced Colorectal Surgical Oncology to gain further expertise to best care for patients diagnosed with cancers of the intestine. He understands the fears patients face with his/her diagnosis, specifically regarding the impact it may have on bowel function. He focuses on these important aspects of a patient’s quality of life, and whenever possible, he uses nerve-sparing surgical techniques that can help to preserve anal, bladder, and sexual function. Dr. Felder has significant experience in complex Robotic minimally invasive surgery, providing optimal surgical outcomes and shortened recovery times. He also has expertise in transanal minimally invasive procedures. He works closely with specialists in medical oncology, radiation oncology, radiology, pathology to discuss individual cases at Moffitt’s weekly tumor board conferences, with the goals of providing the most comprehensive care possible for each patient. Dr. Felder has additional expertise in rectal cancer, personalizing each patient’s treatment to maximize both cancer and quality of life outcomes. His research is largely focused on enhancing the degree of rectal tumor response to treatments, allowing some patients to avoid resection of the rectum, and follow a “watch-and-wait” strategy. Dr. Felder’s research has been presented at national meetings and published in medical journals as well as textbook chapters. He is member of the Clinical Guidelines Committee for the American Society of Colon and Rectal Surgery, the National Comprehensive Cancer Network (NCCN) guidelines for Hereditary (Familial/Genetic) Colorectal Cancer, and on the Scientific Advisory Board for FORCE, a resource empowering patients and families facing hereditary cancer.

The Provider Rating is an average of all responses to specific care provider-related
questions from our nationally-recognized
Press Ganey Patient Satisfaction Survey.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
Patients that are treated in outpatient or hospital environments may receive
different surveys, and the volume of responses will vary by question.
Comments are gathered from specific care provider-related questions from our
Patient Satisfaction Survey . The comments are submitted by patients
and reflect their views and opinions. Patients are de-identified for confidentiality and
We post both positive and negative comments from the surveys. We do not post comments
that are libelous, slanderous, profane, irrelevant or otherwise inappropriate or may
risk the privacy of our patients.
A “[…]” in the comments below indicates de-identified patient information or comments that
are unrelated to the patient’s experience with the visit to the provider, such as
comments related to another provider, about the survey itself, or otherwise completely
Not all providers will have a star rating or comments. In order to ensure accuracy of our
ratings, we only display ratings for providers who have a minimum of 30 completed from
the previous 12 months.
Provider Ratings and comments are gathered from our nationally-recognized Press Ganey
Patient Satisfaction Survey. If a provider does not have ratings or comments listed it
can be for several reasons, including:
The provider has not yet received the minimum number of patient satisfaction surveys
to be eligible for display. We require a minimum of 30 surveys before we post
results to ensure that the rating is statistically reliable and a true reflection of
He or she may be a researcher or other type of provider that does not see patients.
The provider practices in a specialty or office that does not use the specified
surveys currently used for these ratings.
