Overview
Philosophy of care | Effective medical care begins with a deep understanding of each patient’s circumstances and needs. The physician-patient relationship is foundational and must be a two-way dialogue built on trust and respect. I prioritize learning what truly matters to you and your family. I offer treatment recommendations and options that align with your values, preferences and goals. While my clinical focus is on blood disorders and blood cancers, listening carefully and tailoring care to patients is the heart of everything I do. I provide guidance and recommendations, but the decisions ultimately belong to you, the patient. I strongly believe in a team-based approach, where collaboration and communication yield the best outcomes. | Why I entered medicine | When I started college, medicine was the farthest thing from my mind; I was an economics major and took the MCAT on a whim. To my surprise, I scored far better than expected for someone without a science background, and that led me to medical school. Looking back, I can’t imagine doing anything else. Medicine – and caring for patients – has become my true passion. My path into the field was unconventional but led me exactly where I was meant to be. Practicing hematology and oncology isn’t just a career for me – it’s the only thing I can see myself doing. | Community involvement | As a part of cancer center leadership, I participate in local events and charities for patients with cancer and blood diseases, including speaking to the leukemia/lymphoma society. I am particularly fond of events centered around running for cancer charities. | Personal interests | Running is a personal passion of mine – second only to medicine and my family.
