Additional Areas of Focus
Dr. Friedman has provided the following conditions as areas of focus. Please note that we may not have enough data to validate their experience in some of these conditions.
Clinical Research
Clinical research consists of overseeing clinical studies of patients undergoing new treatments and therapies, and publishing articles in peer reviewed medical journals. Providers who actively participate in clinical research are generally at the forefront of the fields and aware of the most up-to-date advances in treatments for their patients.
Duke Cancer Center
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. Dr. Riedel is rated as an Elite provider by MediFind in the treatment of Desmoid Tumor. His top areas of expertise are Adult Soft Tissue Sarcoma, Liposarcoma, Desmoid Tumor, and Angiosarcoma.
Duke Cancer Center
I became an orthopaedic surgeon because I enjoy the mechanical nature of how joints, bones and muscles work together. I chose to focus on treating children because it provides me with an opportunity to make a difference in their health now, and for the rest of their lives. As I’ve entered the later stages of my career, I have had the privilege of seeing patients who I treated come back to me as adults seeking treatment for their own children. I find it very fulfilling to see how the treatments I gave the parent helped them become a healthy, fully functional adult. I believe that being a good doctor means treating the “whole” patient, rather than focusing only on individual parts of the body. I enjoy working with my patients to make sure they are getting all the treatments they need to get and stay well. In my spare time I enjoy photography, hiking and backpacking.
