About me

I believe cancer care begins with listening. My goal is to be a true partner throughout each patient’s medical journey. I take time to explain what is happening, discuss care choices clearly, and talk about what each choice may mean for daily life. Together, we create a plan that reflects the latest science and what matters most to each person. I also welcome family members and caregivers as important partners in care.

Cancer can affect the whole family, and everyone deserves support. I stay current on new treatments and research so I can offer thoughtful care and real hope. For me, it is a priority that each patient feels heard, understands the plan, and feels confident making decisions that match personal goals and values. The relationships I build with patients are at the heart of my work. I want every person in my care to feel seen, supported, and never alone.
