I seek to provide compassionate care to each person and their family.
Aaron Y. Mochizuki, DO



As a pediatric neuro-oncologist, I treat patients with brain tumors as well as other solid tumors. I seek to provide compassionate care to each person and their family.

The awe-inspiring children going through the most challenging circumstances and their incredible families who support them inspired me to pursue my career.

My research examines how brain tumor immune-cell populations change with therapy and how those changes can predict treatment response.

In my free time, I enjoy running, hiking and snowboarding.
