Ron Landmann, MD, FACS, FASCRS Biography and Info
Ron G. Landmann, MD, is a world-renowned expert and invited speaker in robotic surgery for colorectal diseases, specializing in the latest minimally invasive techniques for better patient outcomes and sphincter-preservation. He is the foremost leader in colorectal surgery for cancer and IBD in the North Florida and South Georgia region. He previously served as Consultant and Specialty Council Site Director for Colorectal Surgery at Mayo Clinic Florida from 2008-2018. He serves on the executive committee of the National Accreditation Program for Rectal Cancer. He is also chair of the American Society of Colon and Rectal Surgeons (ASCRS) Rectal Cancer Coordinating Committee. Together, the two organizations oversee accreditation programs and set guidelines and parameters for rectal cancer care in the U.S., within the ACS Commission on Cancer and the National Accreditation Program in Rectal Cancer. By combining his extensive training at top medical centers, national leadership, and bedside manner, Dr. Landmann offers personalized and individualized care for:
- Colon and Rectal Cancer
- Ulcerative Colitis and Crohn's Disease
- Familial Adenomatous Polyposis (FAP)
- Hereditary Non-Polyposis Colorectal Cancer (HNPCC)
- Presacral (retrorectal) Lesions
- Sphincter Preservation/Sparing Surgery
- Ileal Pouch Anal Anastomosis (J-pouch surgery) and Transanal Minimally Invasive Surgery (TAMIS)
About Me
My philosophy of care is simple: I treat every patient like a close, family relative. Patients always come first. Each patient is unique and by incorporating their beliefs and perspectives, I can empower them with the appropriate medical knowledge to make the best decisions. A well-informed patient is the best patient and it is my goal to achieve a successful and healthy, disease-free, partnership together.
I lead the Colorectal Surgery division at Baptist MD Anderson Cancer Center. It is my personal belief that all patients deserve the best personalized, individualized, and expert care for their colorectal cancers and inflammatory bowel diseases. By focusing on these conditions at Baptist MD Anderson Cancer Center, we are able to provide the most up-to-date and cutting-edge care you can receive anywhere – right here in Northeast Florida!
I’ve lived in Jacksonville since 2008, and frequently volunteer my time and resources to benefit charities in our local community. My wife and our two sons also enjoy swimming, hiking, boating, biking, and the tremendous sense of community with our neighborhood and friends.
