Stephanie Johnston joined Cancer Treatment Centers of America® (CTCA) at the Outpatient Care Center in North Phoenix, Arizona, in February 2018. As a Nurse Practitioner, she helps oversee care for patients with all cancer types and stages.

At CTCA®, Johnston is part of a multidisciplinary team focused on managing individualized treatment plans for cancer patients. She is responsible for continuity of care, ensuring accurate diagnosis, personalized treatment, symptom management and survivorship. Johnston also educates her patients and takes time to answer any questions, so that they understand their cancer and treatment options.

“My goal at CTCA is to provide all my patients quality care, personalized to meet their specific needs and goals,” says Johnston. “Throughout treatment, I help my patients experience a positive quality of life by proactively monitoring and quickly addressing side effects they may experience along the way.”

Johnston graduated from Walla Walla University in College Place, Washington, with a Bachelor of Science degree in nursing. She graduated with a Master of Science degree in nursing from Grand Canyon University in Phoenix, Arizona. Johnston has worked in various hospital and clinic settings prior to joining CTCA. She is a member of several professional organizations, including the Advanced Practitioner Society for Hematology and Oncology and Oncology Nursing Society.

Outside of CTCA, Johnston enjoys spending time with her husband, twins and two dogs. She also likes reading, going to the movies and dining out.

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.
