Personal Statement

Our Lymphoma group has been at the forefront in the development of targeted therapies for CLL and other lymphoid malignancies. We strive to bring effective therapeutics to patients, years before they are widely available. I am fortunate to practice oncology in such an exciting era with rapidly improving diagnostic and therapeutic options. I seek to incorporate the latest breakthroughs and technology in providing care to my patients. Comprehensive in my approach, I am driven to understand the underlying biology of the disease, individualizing each patient’s treatment plan. I offer patients a unique experience, with compassion for the patient and their family. With a large portfolio of clinical trials, our group offers ample opportunities for patients to participate in clinical research. Our hospital system is award winning and provides access to world-class consultants for all medical conditions. It will be a privilege to care for you or your family member.
