Pediatricians at Jackson Pediatrics are on the clinical faculty of the University of Washington School of Medicine.  We host medical students at six week intervals through the WWAMI program.  Medical students are always directly supervised by our doctors, who always see every patient who comes in to the office.  It is always your choice whether to allow a medical student to see your child, but we appreciate your participation in our educational efforts.  WWAMI is a Washington, Wyoming, Alaska, Montana, and Idaho cooperative program to help train students from western states without their own medical schools, aiming to return physicians to those rural states.
