story
Going above and beyond her
normal job responsibilities,
Santina has helped collect pro-
duction data for new columns,
closely inspects columns dur-
ing various steps of production
and has developed a system of
identifying problems in “wax-
phase” columns. Because of
her keen attention to detail,
we have resolved several
persistent problemswithwax-
phase columns.
