Dr. David Eckel has been described as the doctor in the Norman Rockwell painting. His emergency care clinic at 6121 NW First Place behind The Oaks Mall is indeed a bit like stepping back in time: Patients' files are lined up in alphabetical order and color-coded like books in a library. There is only one piece of paperwork to fill out, and it's about as minimalist as modern medicine gets: you write your name and address, date of birth and your employer.
