The only no-show at the annual Community Day health fair on Sunday was the LifeFlight helicopter. Mechanical problems kept the aircraft grounded in the morning, then when it was ready to show its stuff to the thousands in attendance, an emergency call came. No matter. The rest of day went off without a hitch.

“I heard there were a lot more people here than last year -- each year it’s growing,” said Sue Nikaido, marketing coordinator with Stanford Hospital & Clinics and health fair organizer with Nancy Sanchez of Packard Children’s Hospital. Departments throughout the medical school and both hospitals were on hand demonstrating everything from robotic surgical tools to bedmaking.
