Get to Know Me

I am a board-certified radiation oncologist specializing in the treatment of metastatic cancers of the spine, brain, and other areas, as well as primary genitourinary cancers, such as prostate, bladder, and testicular cancers.

To manage spine metastases, I work in close collaboration with an excellent team of neurosurgeons, interventional radiologists, physiatrists, medical physicists, nurses, and radiation therapists. Together, we ensure that each patient has a carefully constructed treatment plan designed to best serve their particular needs. When using radiation to treat cancer in the spine, prostate, and other sites, we use advanced techniques such as intensity-modulated radiotherapy (IMRT), image-guided radiotherapy (IGRT), and stereotactic body radiotherapy (SBRT)  to deliver the dose of radiation as precisely as possible.

When I see patients in the clinic, I understand that our meeting often comes at a very vulnerable time. Listening to my patients and tailoring the disease management plan to their individual concerns and care goals is critical. It is also a top priority of mine to clearly convey the reasons behind our recommendations and adjust as needed to accommodate special circumstances. Our whole team is geared toward making the treatment experience as seamless as possible.

I am involved in cancer clinical trials and have a particular interest in using molecular biomarkers to detect cancer and guide treatment across the continuum of cancer care. Outside of the office, I enjoy walks with my family and our dog, tending to our houseplants, and making ice cream. I am always looking for new podcast recommendations.
