Our goal on your first visit
During your first visit with us, you will meet our staff, complete a few brief forms and, of course, meet your doctor. As family physicians, we will try to solve your current medical problem and detect or prevent other health problems. We hope to make the first visit not just an opportunity to deal with any medical concerns you may have but also a time to get acquainted with you.
