About Me
I am a medical oncologist who focuses on bone and soft tissue cancers called sarcomas. I love spending time with my patients. They often have a sense of awareness about their condition that’s truly unique and rewarding. I partner with each patient so they know the full set of options available for treatment and can make an informed decision about the approach that is best for them. I’ve wanted to pursue medicine for as long as I can remember. I find cancer fascinating because of its ability to evade the immune system. The body fails to recognize cancer as being foreign. When I am not at work, I love spending time with my family and enjoy long distance running.

Ratings and Reviews
The ratings and reviews are based on patient responses to the overall provider rating question from the survey. The question reads: “Using any number from 0 to 10, where 0 is the worst provider possible and 10 is the best provider possible, what number would you use to rate this provider?” Responses are converted to a 5-point rating system and applied consistently to all providers. Learn more about our survey process. Patients who see some types of providers receive a different version of the patient satisfaction survey. Those results are not available on DukeHealth.org.

Clinical Focus and Research
I am actively involved in a number of clinically-oriented research projects, including investigator-initiated as well as pharmaceutically-supported clinical trials. I also collaborate with our basic science colleagues to translate laboratory discoveries to the clinic. I serve on the clinical trial committee for SARC, a national collaborative of institutions with sarcoma expertise that is focused on making clinical trials available to patients.

Dr. Reidel is thoughtful and compassionate, but also efficient and mindful of my time. I drive 3.5 hours each way to see him, and he is always on time, allowing me to get back home sooner. He answers every question and is excellent at explaining the plan of care. He sets the standard for good care.
Dr. Riedel and his team were exceptional in every aspect of my care and treatment.
Dr. Richard Riedel was excellent. He was a great listener and he explained things patiently so my husband and I could understand. I am happy to include Dr. Riedel as part of my medical team. Everyone we met were professional, kind and compassionate.
Hard to rate someone that was instrumental in helping you to decide a life alternating event so I will just say Dr Riedel will be my Doctor and I will rely on him going forward
I have total trust in my provider. Explanations are thorough and understandable. I appreciate the continuity of care I have been able to experience and feel very confident in the plan we discussed for the near future. He has a very calming "bedside" manner no matter what the purpose of the visit is or the test results that are delivered.
Dr. Riedel is caring, dedicated, and thorough
Best care anywhere.
Very thorough discussion of prognosis and treatment and answered all questions I had-
