The Patient Satisfaction Rating is an average of all responses to the care provider related questions shown below from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
Comments are submitted by patients and reflect their views and opinions. The comments are not endorsed by and do not necessarily reflect the views of Penn Medicine.
I have an academic focus limited to breast cancer. My research interests have been focused on shortening radiation courses by hypofractionation, intensity modulated radiation therapy (IMRT) with concurrent boost, proton beam radiation, and cardiac effects of radiation therapy/techniques to reduce cardiac dose in breast cancer. I have published over 90 peer-reviewed manuscripts, review articles and book chapters about breast cancer, radiation for early and advanced stage disease, radiation for intact breast and post-mastectomy indications, and radiation therapy techniques and side effects. I am co-chair of the Radiation Oncology breast committee with responsibility for the written board examination for the American Board of Radiology. I am a member of the NRG breast cancer committee local-regional subcommittee.
