Clinical oncology dietitian Rachel Winston says she was attracted to join Cancer Treatment Centers of America® (CTCA) because CTCA recognizes the importance of nutrition in cancer care. Winston also believes the multidisciplinary, comprehensive approach to care is what sets CTCA apart.

“At CTCA, I work with a multidisciplinary team of professionals dedicated to helping patients and their caregivers,” says Winston, a Certified Specialist in Oncology Nutrition.

Winston began her undergraduate studies at the University of Arizona in Tucson, where she obtained a bachelor’s degree in family studies and human development. She continued her education at Arizona State University in Mesa, where she obtained a bachelor’s degree in dietetics. She completed a master’s degree in clinical nutrition at Rush University in Chicago, with coursework that included an 18-month dietetic internship at the university’s medical center.

In June 2013, Winston joined CTCA at Western Regional Medical Center, where she works with medical oncologists, naturopathic physicians, gastroenterologists and nursing staff, among other healthcare professionals. She assesses and closely monitors the nutrition needs of inpatients and outpatients. Winston provides nutrition-focused education and counseling to cancer patients and assists with addressing nutrition needs, including the coordination of intravenous and feeding tube support, when necessary.
