About Me

The best part of my job is getting to know my patients in order to care for them better. The disease process is what we have to manage, but knowing the patient well enables us to approach the process together as a team. Not every medical problem has the same answer for each person and knowing the person gets us to the right answer. I really enjoy caring for my patients and love the relationship we have developed over the years.
