What drew you to Mayo Clinic?

"The culture of Mayo was a big draw for me. There is a genuine commitment to the guiding ethos: 'The needs of the patient come first.' Excellence is the standard for patient care. Education and research are also highly prioritized. Collegiality is the norm, and people are generous in sharing their expertise for patient care and research collaborations. Additionally, as an aspiring physician-scientist, I was looking for a training program with a strong residency program, fellowship program, and research environment. Mayo Clinic checked all those boxes for me."

What aspects of Mayo Clinic’s fellowship program do you feel are unique?

"Each fellow has an individual patient panel, scheduled one half-day a week as our Continuity Clinic. Over the past two years, I have crafted a panel of patients with both hematologic and oncologic malignancies, as well as some benign heme disorders. This panel is built through new patient oncology and hematology clinics, as well as new patients we inherit through our hospital months."
