  This Snowmass21 Contributed Paper addresses the structural changes that need
to occur in the many groups and organizations that intersect with the US
particle physics community to enable impactful public engagement to flourish.
The impetus for these changes should come from the particle physics community,
which should acknowledge the importance of public engagement and act on the
recommendations in this Snowmass contributed paper. Scientists have expressed
frustration at the barriers, penalties and lack of support that discourage them
from participating in public engagement. In this paper, we provide many ways to
create a supportive, enabling atmosphere for public engagement among
physicists.
