“I enjoy the supportive, smiling and positive energy at CTCA,” says Renee Pieroth, clinical oncology dietitian at Cancer Treatment Centers of America® (CTCA) in Philadelphia.

Pieroth joined CTCA® in October 2012. In her role, she assesses patients’ nutritional status and provides individualized nutrition therapy to help patients maintain their health during cancer treatment. She says she appreciates the patient-focused model at CTCA: “CTCA practices integrative care and supports the important role nutrition plays in overall quality of life and treatment.”

Prior to joining CTCA, Pieroth was a clinical dietitian at Riverview Medical Center in Red Bank, New Jersey. There, she formulated nutrition care plans and provided nutrition education and counseling. Before then, she was a registered dietitian and group exercise instructor at Somerset Valley YMCA and Powerhouse Gym in Hillsborough, New Jersey.

Pieroth earned a bachelor’s degree from the Allied Health-Coordinated Dietetics Program at the University of Connecticut, where she graduated magna cum laude. During her undergraduate career, she studied abroad at The Institute at Palazzo Rucellai in Florence, Italy. Following school, she completed an Understanding Oncology course at the University of California, San Diego Extension, which fueled her interest to learn about oncology nutrition.

In addition to providing care to patients, Pieroth helps promote wellness within her community. She is passionate about plant-based meals and helping sustain the environment. She believes nutrition, exercise, and mindfulness are essential for overall well-being.

Patient ratings
Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy at our comprehensive care and research centers. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
