About Me

“The dedication here not only to cancer medicine but also to quality cancer care is a rare gift,” says Dr. Marnee Spierer, a radiation oncologist and Chief of Radiology at City of Hope Phoenix. “I wanted to be part of the effort.”

She began her radiation oncology career as Assistant Professor of Radiation Oncology and Residency Program Director at Montefiore Medical Center/Albert Einstein College of Medicine in New York City.  She spent five years in this academic position and then spent a few years in private practice. She came to City of Hope Phoenix in 2014 and within a year of her arrival, became Medical Director of the Department of Radiation Oncology. In addition to this leadership role, she was appointed Medical Director of Clinical Operations at City of Hope Phoenix.

After receiving her Bachelor of Arts degree at the University of Michigan, Dr. Spierer received her Master of Arts degree in Exercise Physiology followed by her medical degree; both at Columbia University in New York City. She completed her residency in Radiation Oncology at Memorial Sloan Kettering Cancer Center in New York. She recently earned her Master of Business Administration at the University of Michigan, Stephen M. Ross School of Business.

Dr. Spierer has been consistently recognized as an outstanding oncologist and has received numerous awards over the past several years including: Patients' Choice Award, Best Doctors, Compassionate Doctors and Top Oncologists.

Patient reviews
The patient ratings and comments on this page are obtained from an external Press Ganey® outpatient survey provided to all eligible City of Hope patients within one to two weeks of their treatment occurrence. Raw data from the answers to the survey questions about our physicians are calculated by Press Ganey into a one- to five- star rating. In the spirit of transparency, all patient comments are posted as written by the patient, whether they are positive or negative. We only exclude comments if they are deemed to be slanderous or libelous, contain profanity or vulgar language, or do not relate to the patient's experience with the doctor involved.

"Everyone goes above and beyond to make you feel cared for and listened to with all your concerns. [...] I am the person who asks questions just to understand the why of things a little better. I appreciate them explaining things to me to make me feel more comfortable. Sometimes being intubated for 6 hours is a scary thing but I am glad they were able to make me calm down. They made me feel comfortable which you expect from a healthcare provider"

"Amazing provider. The reason I felt comfortable with going through chemo and radiation. I was terrified when I was told I had to start that treatment and have heard negative things about both. She made me feel heard and explained how they truly help and were the best possible avenue to treat my cancer. I am thankful to have had her for my doctor. So much so I even told my mom wait until you meet my other doctor for radiation because she met my OBGYN Oncologist and loved her and I knew she would love Dr. Spierer as well. This rang true as I asked her what she thought as well."
