Dr. Kahn is an enthusiastic and committed physician.

His experience has refined his ability to make decisive choices in the face of complex cancer care. He also establishes deep bonds with his patients, grounded in compassion and empathy. He thrives on the demanding nature of the profession in terms of learning and updating his knowledge base as the field constantly evolves. Importantly, radiation oncology is a field in which he feels endlessly honored and humbled to work.

He also has comprehensive training in clinical trial enrollment to national cooperative group protocols. He enjoys discussing potential clinical trials with patients, if it is in line with their wishes.
