As an attending physician in the Cancer Center at The Children’s Hospital of Philadelphia, I treat children diagnosed with leukemia and lymphoma. My area of clinical focus includes the care of patients with newly diagnosed and relapsed Hodgkin lymphoma.
As a member of our Leukemia/Lymphoma Steering Committee, I help to ensure that the clinical care of patients with this cancer at Children’s Hospital is consistent, carefully monitored and based upon results of the most current clinical research. My own research includes collaboration with those working on projects related to infections in oncology patients, adolescent and young adult care, psychosocial issues affecting oncology patients and the communication of difficult news.
I was the inpatient medical director for eight years and now am the program director of the Hematology/Oncology Fellowship Program. I have a strong interest in trainee education in addition to the development of innovative ways of teaching various topics in oncology.
Along with our wide range of clinical and laboratory research at Children's Hospital, one of the strongest aspects of our program is the depth of experience and knowledge of our team members. We have a hardworking, motivated, collaborative multidisciplinary group. We are always trying to improve the state of safe, clinical cancer care for our patients and families.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above 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.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
