Patient Care Philosophy

My goal is to deliver individualized care of the highest quality to each of my patients. I strive to provide care based on state-of-the-art medical science while remaining focused on all aspects of the patient’s experience—physical, emotional, psychological, and spiritual.

I encourage my patients to participate in clinical research trials when it meets their needs. This often allows patients to have access to the newest and most promising treatments before they are widely available.

I welcome all patients and have expertise in treating all types of cancer. I have particular expertise in treating blood cancers (such as lymphoma, myeloma, and leukemia) and breast cancer.
