About Me

I’ve been interested in pursuing a career in medicine since I was a child. As I continued through my medical training, I was able to see the incredible impact an oncologist has on patients throughout their treatment. I was specifically drawn to patients with cancer and the unique challenges they face. I am fortunate to be working in a field where continued research has allowed us to offer people new treatments with fewer side effects.

My main focus is genitourinary oncology, which includes prostate cancer, kidney cancer, bladder cancer, and testicular cancer. I also see patients with other types of malignancies, as well as benign hematology. Additionally, I perform bone marrow biopsies.

We have a very comprehensive team that focuses on the unique characteristics of each patient. My team and I work closely with urologists and radiation oncologists to develop a treatment plan that takes into account the particular needs of each patient to produce the best possible outcomes.

Each patient is so much more than a diagnosis. All of my patients are treated as individuals who are active members of their treatment plans. My team and I follow patients closely through every aspect of their journey.
