I see patients with blood related cancers, primarily lymphoma. I provide them with comprehensive care from the time they come in for diagnosis until they are cured. Duke is special because I can bring the power of a large medical center with expertise across disciplines together for the care of each patient. One of the nicest parts of my job is the Christmas cards I receive from patients that I’ve treated. For many patients who are doing well, we discharge them from the clinic after five years. The Christmas cards give me the opportunity to see that they are getting on with their lives and to hear about how their families are doing. Outside of work, my wife and I spend a lot of our free time with our two daughters and their children. We like the beach, biking and hiking as a family.

I primarily see patients who have a variety of rare bleeding and clotting disorders. I see both older and younger patients and also provide help when patients need to transition to and away from blood thinners. Doctors usually refer patients to me. I try to work with each patient so they understand why they are seeing me and what is going on with their body. I enjoy when a patient can leave my office with a complete understanding of what is going on and what they need to do to get better. As a young child, I had bad allergies and spent much time in the doctor’s office. As a frequent patient, I enjoyed spending time around medicine. As I entered college, I found that I enjoyed chemistry and that hematology allowed me to combine lab work with patient care.
