Treatment Philosophy

I am a medical oncologist specializing in the treatment of genitourinary cancers.  As a medical oncologist, I work with patients at all phases of malignant disease, which allows me the opportunity to join patients and families on a journey that can be at times both exhilarating and exhausting.  I understand that the patient-oncologist relationship is a unique partnership and one that I take seriously.  The journey of cancer provides access to moments in life that can be emotionally challenging for all parties, and I view my role as one ultimately about providing information and guidance to help navigate the path in the way best suited to each patient.

I find genitourinary oncology to be a particularly satisfying and exciting field within medical oncology.  It includes a diverse group of patients and a variety of different disease with their own unique opportunities and challenges.  It is an area involved in a great deal of research, which has afforded new treatment options for patients, and allows me to be involved in helping patients live longer, live better, and in some instances, even help cure them of their disease.    

Fortunately, at Fox Chase Cancer Center, our faculty and staff are dedicated and united towards one goal – optimally treating patients with cancer.  I completed my oncology training at Fox Chase and was fortunate to be able to continue as an attending physician at this world-class institution.  As part of Fox Chase, our patients have access to the cutting edge of clinical oncology, including the ability to have access to exciting new drugs as part of clinical trials.  Medical oncology is a rapidly evolving world, with new treatments and possibilities continually being made available to improve patient outcomes, and Fox Chase strives to remain at the forefront of those changes.

Bladder Cancer

"In 2018 I was diagnosed with muscle invasive bladder cancer, which seemed like it would end my diving, but also provided me a new way to give back."

Prostate Cancer

I have always been proactive about my health and started having annual prostate exams when I turned 50 in 2007. My first report was great and showed that my PSA level was undetectable.
