• Most of the actions and possible approaches outlined above require an expansion of existing programs or the
creation of new programs and infrastructure. As such, they will require additional staff time/FTE and funding.
While we have been successful in receiving one grant so far, and are pursuing financial support via additional
grants and partnerships with likeminded organizations to augment our ‘in-house’ capabilities, we will not be
able to implement the scale of change desired in the timeframe allotted without new streams of capital, some of
which will be necessary seed funding and others that will be needed mid- and long-term.
