To ensure the accuracy of our patient satisfaction scores, we require that providers who see patients receive
a minimum number of completed patient-submitted surveys before their reviews are listed on their profiles.
Star ratings on this site are collected on a rolling basis from the previous 12 months.
Additionally, some of the physicians listed on our site do not see patients directly, and therefore, do not receive
evaluation and ratings from patients.
Adult malignant and benign tumors of the central nervous system
It has been my long-term ambition to treat patients suffering from cancer. Even before medical school, I had been a member of a cancer research team at Mount Sinai Hospital in New York City where I had the opportunity to contribute to several scientific publications on the subject of breast cancer. As a medical student at St. George’s University School of Medicine I pursued this interest by taking a number of electives in the field. I chose to specialize in radiation oncology because it affords me the opportunity to interact directly with patients on a daily basis and to participate in clinical research programs designed to explore new treatment modalities.
After my internship at Upstate Medical University in NY, I trained in radiation oncology at Johns Hopkins Hospital and obtained broad experience in all subspecialty areas of radiation oncology. In my final year I was appointed as Chief Resident.
Following completion of my residency I received an appointment as attending physician at Brigham and Women’s Hospital/Dana Farber Cancer Institute and was on faculty at Harvard Medical School. I specialized in the treatment of brain tumors and in 2007 was appointed Chief of Adult Tumors of the Central Nervous System Tumors and Radiosurgery.
I have extensive experience with several technologies used in treating cancer patients including stereotactic radiosurgery, hypo-fractionation, volumetric arc therapy and intensity modulated radiotherapy. My research activities are primarily involved in seeking to improve outcomes for patients, and has been presented at national and international meetings, won grants, and been selected for plenary sessions. (see publications).
In 2012 I joined the Department of Radiation Oncology at Fox Chase Cancer Center as attending physician and Associate Professor. I will continue to be involved in the treatment of patients with cancer and also contribute to the development of the brain tumor service. My clinical research activities will, as in the past, focus on developing and assessing new treatment protocols that will provide better outcomes for patients.
As a member of several national and international professional organizations I regularly avail of the opportunity to share and exchange expertise with other specialists in the field. This allows me to continue giving my patients the best in current care.
My treatment philosophy is patient-centered. I believe that patients should be integrally involved in decision making at all stages of their treatment programs. It is my belief that a strong relationship with each patient is central to selecting the best treatment program for his or her clinical needs. Patient confidence is something that I prize highly and constantly strive to attain. Community outreach is also important to me and I regularly contribute to education programs and symposiums organized for the benefit of patients and their families to update them on specific topics pertaining to patient treatment and management.
Finally, it is a great pleasure to me to contribute to the future development of the field of Radiation Oncology through participation in the training programs at Fox Chase Cancer Center for younger colleagues, students, residents and fellows.

I am 40 years old and currently live in Mechanicsburg, Pennsylvania. Although I work as a case manager for an insurance company now, I was previously employed as a full-time nurse. I have always been a busy person with plenty on my plate, so when I started feeling tired and losing weight, I thought it was caused by the stress of my daily routine.
It wasn’t until July 2017 that I couldn’t ignore my symptoms any longer. When I developed a migraine and felt a tremor in my arm and eye, I knew I was about to lose consciousness. I immediately called 911.
Sometimes I think that my timing was just incredible. If I had been diagnosed with cancer a few years earlier, my prognosis would have looked much different than it does today—especially if I had not gone to Fox Chase!
