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.

My goal is not only to provide exceptional medical expertise, but also to support and empower patients, fostering collaboration that prioritizes physical and emotional well-being. | Why I entered medicine | I chose a medical career with a specific focus on cancer care because it offered me the opportunity to seamlessly merge the dynamic advancements in cancer biology with the profound personal connections essential for understanding and supporting my patients. The ever-evolving science of cancer has fascinated me, driving my commitment to staying at the forefront of breakthroughs and innovations. However, it is the deeply personal nature of medicine that truly inspires me – the privilege of learning about my patients, understanding their unique stories and collaborating with them as they heal. This dual passion for scientific progress and compassionate patient care motivates me. | Community involvement | I contribute to public education with the presentation, detection and treatment of lung cancers.

Philosophy of care | Every patient, every time. I treat every patient as I would a beloved family member. It’s what patients expect and deserve: my best anytime and every time. | Why I entered medicine | I studied science in college and was on an internship with a large company when a co-worker got sick.
