Dr. Marc Warmuth is board certified in medical oncology and hematology and practices at our St. Augustine location. He has a special interest in the quality of life aspect of cancer care. Dr. Warmuth says it is possible to treat cancer while maintaining and oftentimes improving a person’s quality of life. “In recent years, a shift away from traditional chemotherapy to targeted and immune therapies has resulted in the ability to treat cancer with far fewer side effects.”  

Dr. Warmuth especially enjoys taking care of patients over time and developing relationships with them and their families. “When I meet a patient for the first time, I like to learn about them as a person — where are they from, what do they do for a living, their hobbies, what family members or other caregivers are involved. This helps me formulate an individual treatment plan that accommodates and supports their lifestyle and treatment expectations,” he says. “I am always inspired by those patients who beat the odds through their sheer determination and the enduring support of their family,” he adds.

Having decided to become a doctor as a young teenager, the Texas native studied medicine at the University of Texas School of Medicine in Houston and completed his internship, residency, and fellowship at Duke University in Durham, North Carolina. At Cancer Specialists of North Florida, Dr. Warmuth feels fortunate to work with a group of dedicated professionals.

“Each member of the team keeps up to date on the latest advances and research in oncology. Ideas are shared in a friendly work environment. Our group has the philosophy that every patient should be treated as an individual.”  

Dr. Warmuth and his wife, Ainsley, have two sons, Robert and Connor. The self-proclaimed family of pet lovers has two standard poodles. “When I am not working, I enjoy running, boating, fishing, and spending time with my family,” he says.
