About Me

Joined MetroHealth: 2025
Academic Affiliations: Clinical Professor, Case Western Reserve University School of Medicine

I’m a hematologist and medical oncologist at MetroHealth, where I specialize in treating cancer and blood disorders. I was drawn to medicine—and especially to cellular therapy—because I wanted to be part of a field that’s constantly evolving. The ability to use cutting-edge science and technology to improve lives is what inspires me every day.

I completed my medical training at Temple University and went on to complete my residency and fellowship in Internal Medicine, Hematology, and Oncology at the University of Maryland and the University of Washington. These experiences shaped my approach to care: evidence-based, compassionate, and always centered around each patient’s unique goals and values.

I also serve as a Clinical Professor at Case Western Reserve University School of Medicine, where I’m proud to help train the next generation of physicians. Whether we’re discussing treatment options or navigating uncertainty together, my goal is to make sure you feel heard, supported, and empowered throughout your care journey.
