A Friendly and Caring Staff

In order to provide the highest level of service, a doctor must surround himself with a staff that is not only competent, but unusually warm and friendly. People like this are not easy to find. Dr. Lee feels very fortunate to have attracted such a quality staff. You’ll notice the difference on your first visit!
