Dr. Seth Felder is a board-certified colorectal surgical oncologist dedicated to the advanced treatment of all colorectal cancers, including colon, rectal, and anal cancers. Practicing in Tampa, Florida, Dr. Felder is a leading expert sought out by patients across the Tampa Bay region and the entire state of Florida for expert diagnosis, complex surgical intervention, and second opinions. He is committed to providing compassionate, leading-edge care for those facing a colorectal cancer diagnosis.

His surgical expertise is highly specialized, encompassing the full range of complex colorectal resections, including colectomy, low anterior resection, abdominoperineal resection, and pelvic exenteration. Dr. Felder emphasizes minimally invasive techniques, frequently utilizing robotic-assisted surgery to enhance precision, minimize patient recovery time, and preserve function. He routinely performs a high volume of these procedures, ensuring patients benefit from his extensive experience in achieving the best possible outcomes and quality of life. 

At Moffitt, Dr. Felder holds key leadership roles that benefit all his patients. He serves as the Section Chief of Rectal Cancer and the Director of the Rectal Cancer Multidisciplinary Tumor Board. This is a vital component of his practice; every patient’s case is reviewed by a subspecialty-trained GI team of experts, including medical oncologists, radiation oncologists, radiologists, and pathologists, to formulate a truly personalized treatment plan. This collaborative approach ensures comprehensive and integrated care from diagnosis through recovery for all forms of colorectal disease.

As a well-respected leader in his field, Dr. Felder drives clinical advancements through research, serving as a principal investigator for clinical trials, such as an important study focusing on MRI-guided adaptive radiation for locally advanced rectal cancer.  He has co-authored national guidelines for major surgical and oncology organizations (NCCN, ASCRS, ASTRO) and is recognized for his clinical excellence, including being honored as a Tampa Magazine Top Doctor in Colon and Rectal Surgery (2022–2025). Dr. Felder completed his advanced colorectal surgical oncology training at Memorial Sloan Kettering Cancer Center, following a colorectal surgery fellowship at the University of Minnesota and a general surgery residency at Cedars-Sinai Medical Center.

Dr. Felder is currently accepting patients.  Patients can be seen within a week for surgical consultation.  No referral is needed.
